Installation and Operating Instructions

This manual describes the installation and operating procedures for the 1641 Series (M-2, S-2) Single-Channel Receiver.

Receivers are designed as the remote control device for operation of a motorized camera Pan/Tilt unit and a motorized camera

lens unit. Since camera sites are often a great distance from the operator’s viewing location, these receivers provide the operator

with positive control of the camera site. Receivers also provide the operator with control of auxiliary devices such as lights,

doors, etc. at the camera site. Receivers are individually coded for each camera site so only the camera under observation will be

controlled by the operator.

DESCRIPTION

The 1641 Series Receivers are used with Matrix Switching

Systems to control pan, tilt, zoom, focus, iris, and auxiliary

functions at a camera site. These Receivers are classified as a

single-channel type since the unit controls only one camera at a

site.

All 1641 Receivers are capable of controlling either standard

rotation or 360 degree rotation Pan/Tilt units. In addition, each

Receiver may be configured by the user to provide no preset,

standard preset, or 360 degree preset capability. To

accomplish 360 degrees of preset callback, the 1641 Receiver

works with pan preset potentiometers which contain two out-

of-phase ramp outputs.

The 1641 Series Receivers also features standard autopan and

electronic autopan that can be programmed for either unlimited

panning action or for a 30-minute timeout.

Receivers obtain control instructions via common code lines

originating from switching system CPUs, the system input

bays, intervening code distribution units, or other units capable

of generating the proper control codes. To enable each

Receiver to identify those control signals intended for it, each

Receiver must be set up at installation to identify the camera

number with which it is to be associated.

Receiver Models

The 1641 Series Receivers are suppied in several models

requiring different control interfaces, pan/tilt currents, and

power sources. Model number coding reflects the

aforementioned variables. In some cases, additional coding

reflects compliance with the requirements of certain regulatory

authorities.

The first letter suffix to the model number designates the

control interface. 1641 “M” models are designed to receive

AD Manchester Control Code generated by American

Dynamics Matrix Switching Systems and accessory Control

Code devices. “S” models are designed to receive RS-232

code from RS-232 control devices.

The “-2” suffix to the model number identifies the Pan/Tilt

current provided by the unit. The “-2” model provides 0.5 to

1.0 amps for the pan motor and 0.5 to 1.0 amps for the tilt

motor, or 2.0 amps total current (diagonals).

The 1641 Receivers can be ordered for 24VAC, 120VAC, or

230VAC input voltage. An “AD” prefix, and the absence of a

suffix, indicates 120 VAC, 50/60 Hz power. An “F” suffix

indicates 24VAC, 50/60 Hz power. An “X” suffix indicates

230 VAC, 50/60 Hz power. A “2F-1” suffix indicates EU

compliance, and indicates the product bears the appropriate

“CE” labeling.

For a complete list of current product codes, see the

Specifications page at the back of this manual.

A NEMA-4 kit Model 1641E KIT is available for outdoor

installation.

FEATURES

Pan/Tilt and Lens Control

As shipped, the 1641 Receiver provides drive outputs at 24

VAC for control of Pan/Tilt motors and 10 VDC output for

lens control. The lens output voltage can be varied from 7 to

12 VDC with a potentiometer located on the side of the unit.

A 12-pin connector on the side of the unit contains all the

connections required for control of the Pan/Tilt and lens.

Note: Certain Pan/Tilt units require alternate voltages other

than those noted in this manual. If necessary, call the

Service Center for information or assistance.

Type -2 Models

Pan Motor 24 VAC 1.0 Amp (see Note )

Tilt Motor 24 VAC 1.0 Amp (see Note )

Iris Motor 8 to 12 VDC .05 Amps

Focus Motor 8 to 12 VDC .05 Amps

Zoom Motor 8 to 12 VDC .05 Amps

Note: The total of all 24 volt Pan/Tilt motor currents and

auxiliaries is not to exceed 2.0 amps for continuous

operation on 1641-2 models.

Auxiliaries

Two form “C” relays are provided for auxiliary use, either for

latching or momentary operation control. The relay contacts

are for use with an external power source not exceeding

24VAC or 30VDC, and a load current not exceeding 1 Amp.

See Receiver Configuration Setup, page 4, to configure these

relays for latching or momentary operation.

Auto Sense

The 1641 has automatic sensing of pan/tilt and lens servo

voltage direction at initial power up when preset scenes are

enabled. This feature determines the polarity of the connected

reference voltages in order to determine proper motor direction

control. (See page 14, Power-up Auto Sense.)

Preset Scene

The Preset Scene feature allows the operator to select and store

in the Receiver memory a specific camera scene, and to recall

that scene at a later time via keyboard commands. Preselection

of a scene is available only for Pan/Tilt and Lens units with

feedback potentiometers. The pre-selected scenes, also known

as a Programmed Scene, are saved in non-volatile memory for

protection in the event of a power failure.

When controlled by a Matrix Switching System, the 1641

Series Receiver can be programmed for 71 preset scenes for

that camera. (Note: This differs from the American Dynamics'

standard of 72 presets per camera.) Refer to the installation

and operation manuals for the particular Matrix Switching

System for programming procedures. Note that the setting of

position 1 and 2 on DIP Switch S7 (See SETUP, page 4,

determines if preset scenes are enabled for the unit. All units

are shipped from the factory with preset scenes enabled.

Automatic Panning

The 1641 Series Receiver is capable of either Automatic

panning using Presets or Automatic panning using an

auxiliary.

Automatic Panning using Presets

The 1641 Series Receiver is capable of automatic panning

using preset end stops for a Pan/Tilt unit with preset capability.

When initiated by the operator, the automatic camera panning

will operate either continuously or for a 30 minute period,

depending on the Setup option chosen (see DIP Switch S7,

position 6, page 4).

Automatic Panning using an Auxiliary

The 1641 Series Receiver is capable of automatic panning

using an auxiliary relay (Aux 1) for a suitably equipped

Pan/Tilt unit which has internal Autopan capability. The

internal autopan control is provided by changing the Receiver

auxiliary 1 relay from a unpowered relay to a powered relay

with 24 VAC on it (see Setup, Autopan using Auxiliary 1,

page 5).

Note: The total of all 24 volt Pan/Tilt motor currents and

auxiliaries is not to exceed 2.0 amps for continuous

operation, (see notes to Table 1).

FEATURES

INSTALLATION

This installation should be made by a qualified service person

and should conform to all local codes. Safeguards must be

taken to avoid unintentional operation by employees, janitors,

and cleaners working about the premises, by falling objects, by

customers, by building vibration, and by similar causes.

Preparation

There are many switches that must be set up before operation

of this product, as described in SETUP, pages 4 and 5. An

incorrect setting may result in damage to this unit and any

other device(s) connected to it. Check all wiring and cabling

before applying power.

Mounting

Receivers are for indoor use only, except models with an

“

E”

suffix. Indoor models may be surface mounted with any

orientation. Mount Receivers near the cameras to be

controlled to minimize voltage drop in the wiring.

The dimensions of the Receiver housing are: 2" H x 7-1/2" W

x 8-1/2" L, without the mounting ears. See Figure 2 below for

mounting hole dimensions with the mounting ears.

Mount with 1/4-inch bolts appropriate to the type of mounting

surface. For mounting to wood studs, use lag bolts (with a

drilled pilot hole) or wood screws which penetrate the wood

for at least one inch. In concrete, use lead or plastic anchor

expansion bolts with a minimum pull-out rating of 10 pounds.

For steel surfaces, drill four bolt clearance holes and use bolts

with lockwashers and nuts. When mounting to drywall

(gypsum) wallboard, use toggle bolts. Drywall thickness must

be at least 3/8-inch.

Models with an

“

E” suffix are provided with a NEMA 4,

fiberglass reinforced polyester, non-corrosive weatherproof

housing. Mount these units with the hinged side facing to the

left. Follow the instructions for the liquid-tight fittings packed

with the unit.

SETUP

Camera Number Setup

For 1641M and 1641S models:

A 10-position DIP switch labeled “CAMERA ID” is used to

associate a specific camera number with the Receiver for

individual control by the Matrix Switching System. This

switch, labeled S10 on the main PCB, is located on the side

panel of the 1641 Receiver, near the Pan/Tilt/Lens cable and

the LENS ADJ control (see Figure 1, page 1). Set this DIP

switch to the camera number assigned by the Matrix Switching

System. See the tables in the Appendix for the proper DIP

switch settings for system camera numbers.

Lens Voltage Adjust

The 1641 can be adjusted for a range of camera Lens servo

voltages. The lens output voltage can be varied from 7 to 12

Volts DC with a potentiometer, labeled “LENS ADJ”. This

control is located on the side panel of the 1641, near the

CAMERA ID switches (see Figure 1, page 1).

Receiver Configuration Setup

The 1641 Receiver must be configured for the type of

auxiliaries used, the preset capabilities, and for the type of

control interface. An internal DIP switch located on the main

1641 PCB, labeled S7, is provided to set the Receiver

configuration (Figure 3). See Figures 4, 5, and 6, on pages 6,

7, and 8, for the location of DIP switch S7 on the main PCB.

CONNECTIONS

Code Line Connections for AD Manchester Control Code

(1641M Series)

The 1641M code line connector (J1) is a 3-position terminal,

labeled “W”, “S”, and “B” on the side panel of the unit (see

Figure 1, page 1, and Figure 4, page 6). A mating 3-position

screw-terminal plug is supplied.

Wiring:

Use 18 AWG, shielded, 2-wire cable, Belden 8760 or

equivalent (for plenum, Belden 88760), for 1641M code line

connection. The maximum code line length is 5000 feet.

Connections are made by inserting the appropriate signal wires

into the slots of the mating connector and tightening the hold-

down screws. When all wires have been connected, insert the

mating connector into the code connector on the 1641M.

1. Check the power line to verify that the power is off.

2. Insert and screw down the Black Code wire into the screw

terminal marked B.

3. Insert and screw down the White Code wire into the

screw terminal marked W.

4. Insert and screw down the Shield wire into the screw

terminal marked S.

The 1641M Receiver has a 120-ohm terminating resistor

installed on the Receiver code input line and is designed for a

“Star” connection to a code distribution unit (see Figure 7).

If the 1641M is used in a “Daisy Chain” configuration, the

120-ohm terminating resistor must be removed from all but the

last Receiver (see Figure 8). This termination can be

eliminated by removing Jumper J6 on the Receiver Module

PCB. Refer to Figure 4, page 6, for the location of J6 on the

Receiver Module PCB. A 120-ohm termination must be

provided on the last piece of equipment on the line.

The green LED labeled “CODE” on the 1641 Receiver

illuminates when the unit is receiving valid code. The LED

stays illuminated for 5 seconds after the code is removed. A

flickering Code LED indicates a problem in the transmission

of the code, poor or loose connections, improper termination,

or a defective Receiver.

T + 1 Transmit (XMIT)

Ground symbol 2 Ground (GND)

T - 3 No Connection

R + 4 Receive (RCD)

Ground symbol 5 Ground

R - 6 No Connection

Wiring:

Use 18 AWG, shielded 3-wire cable, Belden 8770 or

equivalent, for RS-232 connection to the 1641S. Connections

are made by inserting the appropriate signal wires into the slots

of the mating connector and tightening the hold-down screws.

For proper RS-232 communications, the EIA Standard DTE

(Data Terminal Equipment) pin designations of each piece of

equipment must be observed. All American Dynamics

equipment, including the 1641S, are configured for DTE

operation. For DTE/DTE connection to the 1641S Receiver:

1. Verify that the power is off.

2. Connect XMIT of the RS-232 device to RCD, pin 4, on

the 1641S connector.

3. Connect RCD of the RS-232 device to XMIT, pin 1, on

the 1641S connector.

4. Connect GND of the RS-232 device to GND, pin 2 or 5,

on the 1641S connector.

RS-232 cable shield connections are made at the connectors

attached to the controller or code distributor only.

See the Appendix for typical RS-232 connections.

For distances of 1000 ft (330 m) or less between the Receiver

and RS-232 devices, a direct connection using RS-232 cable

with mating connectors may be used. For distances over 1000

ft, RS-232 connections require a link using either

asynchronous line drivers over dedicated cables, short-haul

modems over dedicated phone lines, or dial-up modems over

conventional telephone lines.

The green Code LED on the side of the 1641S Receiver is

illuminated when the unit is receiving valid code. If this LED

does not light, a problem in the transmission of the code, a

poor or loose connection, improper termination, or a defective

Receiver may be indicated.

RS-232 Baud Rates

For continuous operation of a Receiver from a switching

system keyboard, the RS-232 communication data rates must

be compatible. The minimum baud rate for communication

between the switching system and the 1641S Receiver depends

on the number of keyboards in use with the switching system.

The following Receiver communication baud rates are

suggested for the number of system keyboards in use:

1 keyboard 1200 Baud

2-3 keyboards 2400 Baud

4-9 keyboards 4800 Baud

over 10 keyboards 9600 Baud

See page 5 for baud rate setup of the 1641S Receiver.

Preposition and Auxiliary Cable

The connection to Pan/Tilt preposition servos and auxiliary

equipment is with a 14-pin connector. This connector, labeled

J21 on the main PCB, is located on the side of the unit opposite

the power cord (see Figures 4, 5, and 6, pages 6, 7, and 8). A

mating 14-position screw-terminal connector plug is provided.

Table 9 lists the Receiver pin designations and provides space

for the installer to record the preposition and auxiliary pinout

designations for the specific installation.

Note: If the Preposition wiring or Preset switches (page 4) are

changed, the unit must be power-reset, see page 14.

When wiring the connector, insert each wire carefully with

approximately 1/4 inch of insulation removed. Screw down

the clamping screw on each pin of the connector.

Auxiliary Wiring:

1. Check the power line to verify that the power is off.

2. Locate the Preposition/Auxiliary connector on the

Receiver.

3. Insert the Hot wire of the auxiliary into the pin location for

the desired Aux (1 or 2) Relay Common.

4. Insert the Return wire of the auxiliary into the pin location

for Aux (1 or 2) Normally Open or Aux (1 or 2) Normally

Closed, depending on the type of use of the auxiliary.

Note: As shipped, Aux 1 is to be used as a looping relay only.

For Auto Pan use, the Aux 1 relay is changed to a powered

relay (see page 5). Insert the Auto Pan wire of the Pan/Tilt

unit into the pin for Aux 1 Normally Open. The ground for

this 24VAC signal is provided by the Pan/Tilt Common pin

on the Pan/Tilt connector, page 12.

Pan/Tilt Preposition Wiring:

1. Check the power line to verify that the power is off.

2. Locate the Preposition/Auxiliary connector on the

Receiver.

3. Insert the Pan (Wiper) wire of the Pan/Tilt unit into the pin

location for Pan 1 Pot.

4. For a 360 degree preset Pan/Tilt unit, insert the second Pan

(Wiper) wire into the pin location for Pan 2 Pot.

Note: Pan 1 and Pan 2 are references only. The Pan (Wiper)

wire of the Pan/Tilt unit can be wired to either Pan Pot pin.

5. Insert the Tilt (Wiper) wire of the Pan/Tilt unit into the pin

location for Tilt Pot.

6. Insert the Focus (Wiper) wire of the Lens unit into the pin

location for Focus Pot.

7. Insert the Zoom (Wiper) wire of the Lens unit into the pin

location for Zoom Pot.

8. Insert the Servo (+) wire of the Pan/Tilt unit into the pin

location for (+) REF.

9. Insert the Servo (-) wire of the Pan/Tilt unit into the pin

location for (-) REF.

Note: (+) REF and (-) REF are voltage direction indicators.

The 1641 has automatic sensing of pan/tilt and lens servo

voltage direction at initial power up to determine the

polarity of the reference voltage connections. (See page 14,

Power up Auto Sense.)

10. For outdoor installations, or where required by local codes,

insert the cable shield wire for each separate cable into the

pin location for Shield.

OPERATION

Powering Up

The 1641 Receiver has a pendant cord for use with a standard

electrical outlet. The power required for each model is

inidicated on the Specifications page at the back of this

manual.

Model ADS1641M-2F-1 is considered to be Class III

equipment as defined in EN60950.

The 24 VAC source for this unit must be provided from SELV.

Use a EN60950 compliant transformer having a SELV output.

The Receiver circuitry includes two transformers: one for the

on-board circuitry, which has a non-replaceable thermal fuse;

and the second for the Pan/Tilt and Auxiliary output, which

has a replaceable fuse. If the replaceable fuse should blow,

check all external wiring. Repeated fuse blowing indicates

improper wiring, defective Pan/Tilt units, or excessive

Auxiliary loads. Use the proper fuse value according to the

1641 model number.

AD (1641M-2/S-2) 250 VAC, 0.7 Amp for 120 VAC

AD (1641M-2X/S-2X) 250 VAC, 0.4 Amp for 230 VAC

AD (1641M-2F/S-2F) 250 VAC, 4 Amp for 24 VAC

AD1641M-2F-1 250 VAC, 4 Amp for 24 VAC

Note: For all units, replace with time delay type fuse.

The green LED labeled “POWER” on the side panel of the

1641 Receiver illuminates when the unit is powered. If this

LED does not light, a poor or loose power connection or a

defective Receiver may be indicated.

The green LED labeled “CODE” on the side of the 1641

Receiver illuminates when the unit is receiving valid code.

The LED stays illuminated for 5 seconds after the code is

removed. If this LED does not light, a problem in the

transmission of the code, a poor or loose connection, improper

termination, or a defective Receiver may be indicated.

Power Reset

When any changes are made to the Pan/Tilt Preposition wiring

or Preset switches, the 1641 must be power-reset. To power-

reset the Receiver, unplug the unit from the power source, wait

for 5 seconds, then plug it back into the power source.

Power Up Auto Sense

If the 1641 is set up for presets (page 4), on initial power up

the unit performs an automatic determination of the reference

voltage sense for the pan/tilt and lens connections. The 1641

commands the camera to pan, tilt, and change iris, zoom, and

focus to determine the polarity of the reference voltage

connections. Following this sequence, the camera is returned

to the scene positioning that existed prior to this sequence.

Autopan Operation

Automatic Panning using Presets

The 1641 Receiver provides automatic panning using preset

end stops for a Pan/Tilt unit with preset capability.

To configure Autopan:

1. Position the camera to the desired start position (first

Autopan end stop).

2. Enter 70, then press SET SHOT on the keyboard.

3. Position the camera to the desired stop position (second

Autopan end stop).

4. Enter 71, then press SET SHOT on the keyboard.

Note: If the preset scene for shot 70 is subsequently changed,

the information for preset shot 71 must be re-entered.

To start Autopan operation:

Enter 72 then press CALL SHOT on the keyboard. The

1641 Receiver uses the positions stored in Set Shots 70 and

71 to determine the Autopan operation.

Note: Preset Shot 72 cannot be used as a preset scene in the

1641; it is reserved for use as the Autopan callup. Preset

Shots 70 and 71 can be used both as Autopan end stops and

as normal preset scenes for callup from the keyboard.

To stop Autopan operation:

If the Autopan operation is set to 30 minutes by the setup

switches (page 4), the camera continues panning between

the two end stops until the 30 minute period elapses.

If set for continuous panning, the camera continues panning

until manually stopped by the operator, either by calling a

preset shot or by using the keyboard pan functions (joystick

or direction buttons).

Automatic Panning using an Auxiliary

The 1641 provides Autopan control for a suitably equipped

Pan/Tilt unit which has internal Autopan capability. This

internal Autopan control is provided by configuring the Aux 1

relay for 24VAC output (see Autopan Setup, page 5).

To activate or start Autopan, set AUX 1 to ON.

To deactivate or stop Autopan, set AUX 1 to OFF.
