A typical example of where these modems are used in a PSTN is shown in Figure 1. This network

contains four Bristol Distributed Process Controllers equipped with Bristol 9600 bps - PSTN Modems

operating in a master/slave configuration. During operation, the master controller dials up and

communicates with each slave (remote) at prescribed intervals to send and receive data. The interval of

dialing is a function of the application software that is executed by the master device.

The modem's transmitter output, as measured with 600-ohm termination (typical for telephone lines) is -

10 dBm (Fixed). This qualifies the modem for use with any voice grade PSTN hookup in compliance with

FCC "Loop Start" requirements.

The Bristol 9600 bps - PSTN Modem has been designed to provide the following features:

• Operates on 2-Wire (Loop Start) Switched Networks (PSTN) only.

• CCITT compatibility (see Table 1)

• Compatible with Bell 212A @ 1200 bps (600 baud) and Bell 103J @ 0-300 bps.

• AutoDial/AutoAnswer operation.

• Smart programming based on the Hayes “AT” command set.

• Storage of all parameters in non-volatile memory.

• Standby Mode - Consumes minimal power until activated by phone or DTE.

• MNP Class 2-4, MNP 10 & V.42 Error Correction.

• MNP 5 & V.42 bis Data Compression.

• Data Access Arrangement (DAA) with 1000 Vac Isolation.

• Surge withstand of 100A with 10 x 160μS waveform.

• Bristol 9600 bps PTSN Modems contains up to three factory-configured Configuration Jumpers that

function as follows:

JP1 - Modem Sleep (Power Save) Selection

- Installed = Enable Sleep (Power Save) Mode

- Removed = Disable Power Save Mode

With JP1 installed, the modem’s power will be removed after no activity for 10 seconds. The modem’s

power will be reconnected if pulses are detected at the Ring indicator pin or if activity is detected at

the DTR pin. Note: The modem requires 2-3 seconds after power has been restored before it can

receive AT commands.

JP2 - RTS to CTS Loopback Selection (Field Configurable)

- JP2-1 to JP2-2 = CTS from Modem (Factory Setting)

- JP2-2 to JP2-3 = CTS Connected to RTS

JP3 - LED Enable Selection (Field Configurable)

- Installed = Enable LEDs (Factory Setting)

- Removed = Disable LEDs (Low Power Mode)

• Bristol 9600 bps PSTN Modems contain nine (9) LEDs. When Jumper JP3 has been removed, these

LEDs are disabled. These LEDs function as follows:

TXD (Transmit Data) - CR10 - When lit this LED indicates transmitting activity. Both MARK and

SPACE data (TXD) from the host device (DTE) are sent to the local modem (DCE) at J2-3.

RXD (Receive Data) - CR11 - When lit this LED indicates receiving activity. Both MARK and SPACE

data (RXD) are being sent from the local modem to the host at J2-2.

CI-9600TF Section 1 Introduction / 1-5

RTS (Request to Send) - CR12 - When lit this LED indicates that the host is ready to send data to

the local modem.

CTS (Clear to Send) - CR13 - When lit this LED indicates that the local modem has signaled the host

that it is clear to receive data. CTS is issued in response to an RTS.

DTR (Data Terminal Ready) - CR14 - When lit this LED indicates that the host has activated the

local modem.

DCD (Data Carrier Detect) - CR15 - When lit this LED indicates that the local modem has detected

the presence of a carrier from a remote modem.

DSR (Data Set Ready) - CR16 - When lit this LED indicates that the local modem is ready to send or

receive data to/from the remote modem.

RI (Ring Indicator) - CR17 - When lit this LED indicates that the modem has detected the presence

of a ring on the phone line.

PWR (Power) - CR18 - When lit this LED indicates that power has been supplied to the modem.

Jumper JP3 must be installed to enable all LEDs.

CI-9600TF Section 2 PC Configurable Options / 2-1

Section 2

PC CONFIGURABLE OPTIONS

2.1 PC CONFIGURABLE OPTIONS

All modem configuration parameters and options must be configured via software. Configuration occurs

via an ASCII Terminal (or a PC equipped with Terminal Emulator Soft-ware) and the modem's RS-232

Configuration/Data Port, i.e., the 9-pin D-type Connector J2. Note: Use a standard RS-232 Cable, i.e., Pin

1 to Pin 1, Pin 2 to Pin 2, etc. The RS-232 Configuration/Data Port will not respond to configuration

messages during an active phone connection

Note: The PC/Terminal Emulator must be set for 9600 bps DTE speed while configuring the

modem.

The modem is factory set for use in the product in which it will be installed. This is accomplished by

invoking a stored profile contained in non-volatile memory. If it is desired to switch, modify or simply

observe the current stored profiles, a PC equipped with terminal emulation software such as

HyperTerminal or Procomm, or an ASCII terminal must be connected to the modem's RS-232

configuration port. For all products, the terminal's speed must be set for 9600 bps. The modem will

remember the last DTE speed at which it communicated with the terminal.

To view and verify the active and stored profiles, type AT&V, then press ENTER. The following data

should appear:

ACTIVE PROFILE: (Should match the stored profile below. Other "S" registers may be included)

STORED PROFILE 1: (For 3530-XXX Modems)

B1 E0 L1 M1 N0 Q0 T V1 W0 X4 Y0 &C1 &D0 &G0 &J0 &K0 &Q5 &R1 &S0 &T5 &X0 &Y1 (note: &Y1 in

Active Profile ONLY) S00:001 S02:043 S06:002 S07:050 S08:002 S09:006 S10:014 S11:095 S12:050

S18:000 S36:007 S40:104 S41:192 S46:136 S95:000

If the NVRAM is not installed or is not operational as detected by the NVRAM test, the following message

is displayed: NVRAM FAILED OR NOT INSTALLED.

If different profile data appears, the modem must be re-profiled by issuing the following command string:

AT&F S0=1 &C1 &D0 &K0 %C0 E0\V1 ENTER (Carriage Return)

AT +A8E=,,,0 ENTER

AT&Y1 &W1 ENTER

Note: Power down the modem and then re-apply power to ensure that Stored Profile 1 is placed

into the Active Profile.

If re-profiling was performed the AT&V command should be re-issued to observe and verify the correct

profile data.

The modem will normally (by default) force stored profile 0 to become active on power-up.

The modem should now be ready for use in a PSTN network operating at a maximum line speed of 9600

bps. All modem features, including data compression, error detection, speed buffering and auto-bauding

are enabled. In this configuration, the modem will automatically adjust its line speed to the highest pos-

sible value, based on line quality. The line speed may drop down to 1200 bps, while the 3530XXX

terminal speed is still operating at 9600 bps.

2.2 14.4 Kbps OPERATION

If desired, network performance can be increased somewhat by allowing a maximum modem line speed

of 14.4 Kbps without re-profiling. The master and any or all slave nodes may be modified for this feature.

This includes all Bristol products. Follow steps 1 through 3 below to achieve this capability:

1. Edit each ACCOL load for the master and slave nodes to be modified by increasing the network

port speed to at least 19.2 Kbps (38.4 Kbps maximum).

2. Using a PC running terminal emulation software, i.e., HyperTerminal, Procomm, or an ASCII

terminal connected to the modem’s configuration port, access each modem at the network speed

specified in each load using the AT&V ENTER command.

3. If possible, re-configure the cold start default rate for each slave node, so that cold-downloads via

the PSTN network are possible.

MODEM INSTALLATION & SETUP PROCEDURES

Caution

PC board components can be damaged by electrostatic discharge (ESD) during handling, i.e.,

disassembly, reassembly, and test procedures. Use grounded wrist straps and surface pads when

working near or handling any Bristol Circuit Board. Refer to Bristol supplement manual S14006 for proper

ESD grounding and handling techniques.

3.1 INSTALLATION INSTRUCTIONS

Bristol’s 9600 bps - PSTN Modem is intended for use on the Public Switched Telephone Network (PSTN)

operating in North America as illustrated in Figures 1-1 & 3-26.

Installation of the modem versions is provided as follows:

Section 3.1.1 - 3530-10B, -50B & -15B Modem

Section 3.1.2 - 3530-20B & - 25B Modem

Section 3.1.3 - 3530-45B Modem

Section 3.1.4 - 3530-55B Modem

NOTE:

The final installation step for each 3530-XXX instructs the user to, “configure the 3530-XXX using a PC

equipped with either the Bristol TMS or UOI program.”

9600 bps - PSTN Modems are powered by the 3530-XXX’s Auxiliary Power Output Connector. Units

shipped from the factory, with a modem installed, have the Auxiliary Power Output set ON in the standard

load shipped with the product.

If you want the modem powered continuously, and

• you have since re-downloaded your standard load, -or-

• you are running an ACCOL load other than the standard load shipped from the factory, -or-

• you are installing a modem for a unit which originally shipped without a modem,

then you MUST set the Auxiliary Power Output to ON. This can be accomplished, for standard loads,

using the TeleFlow Menu System (TMS), by setting the Auxiliary Power Output Default to ON via the

Radio Communications Setup Menu (See Section F.8.5). If you are NOT using one of the standard loads,

you must use the SYS_3530 Module in your ACCOL Load to set the Auxiliary Power Default ON/OFF

signal to ON. (This signal is Entry 1 in Parameter List 4 of the SYS_3530 Module, see ‘SYS_3530’

section in the ACCOL II Reference Manual, document# D4044).

3.1.1 Installing a 9600 bps Modem into a 3530-10B, 15B or 50B

3530-XXX modems (associated with TeleFlow -10B, TeleRTU -15B & TeleFlow Corrector -50B) are

mounted on a Modem Mounting Bracket which in turn is installed on a Radio/Modem Mounting (see

Figures 3-1 & 3-2). To install a modem into a 3530-10B/15B or 50B, follow steps 1 through 9 below. Note:

The procedure for installing and configuring a TeleFlow 3530-10B, TeleFlow Corrector -50B or TeleRTU -

15B is covered in Instruction Manual CI-3530-10B, CI-3530-50B or CI-3530-15B respectively.

1. Disconnect power from the 3530-XXX (shut down or place under manual control any critical

processes prior to disconnecting power).

2. Open the Instrument Front Cover. To open the Instrument front Cover, remove the lock, if

present, and turn each of the three captive screws a quarter (1/4) turn counterclockwise.

3-2 / Modem Installation Section 3 CI-9600TF

3. Loosen the four screws that secure the Radio/Modem Mounting Bracket to the Battery Mounting

Bracket. Slide the Radio/Modem Mounting Bracket to the left and remove it.

4. Install the modem onto the Modem Mounting Bracket. Install the Modem Mounting Bracket (with

modem installed) onto the Radio/Modem Mounting Bracket (removed instep 3).

5. Connect the modem's D-type Port (J2), and connectors TB4 to the appropriate TeleFlow CPU

Board Connectors (see Figures 3-2, 3-3, 3-4 & 3-5 and Table 3-1).
