Control
Code
Converter
Ins tallation Instructions
The
1983
Code Converter, for use with American Dynamics switching systems, enables control
of
a Receiver at a
distant camera site via an
RS-232
communication link.
Two
Code Converters are required per
link:
one Code Converter
is
located
at the switching system end
of
the link and operating in a transmit mode. The other Code Converter
is
located
at the distant site and operating
in
a
receive mode.
A
switch
sets
the operating mode. In the transmit
mode,
Control
Code from the Switched Controller is converted to an
RS-232
signal. In the receive mode, the
RS-232
signals are
converted back
to
Control Code
for
Receivers at the distant camera sites.

INSTALLATION
MOUNTING
RS-232
Connector
The Code Converters are supplied as free
desk
mount standing
units. For rack mounting, use AD21 17 Series Rack Mount kits.
Mount one of the
two
Code Converters
in
a convenient location
near the Switcher/Controller
or,
if used, a Code Distributor.
Mount the second at the distant site near the Receiver
to
be
controlled
to
minimize Control Code wiring. Avoid heat sources
or
poorly
ventilated racks.
The %pin modular phone connector, labeled RS-232, is used on
the code converters for the RS-232 link.
This output can be used on a hardwire system up to 1000 ft.
between units. This output can
also
be used with user supplied
telephone modems
so
that a command can be sent over the
telephone lines.

CONNECTIONS
RS-232 CONNECTOR PINOUTS
The 12-pin
CODE
YO
connector on the rear panel

below. A mating plug is supplied. Connections
for Code Converters at the Switcher/Controller (Receive Control
Code/Transmit RS-232) and those at the distant site (Receive
RS-232Rransmit Control Code) differ.
Code Converter

BAUD RATE
The communication speed of the RS-232 is set at
9600
baud
prior to shipping.
To
change the baud rate:
1. Disconnect the power.
2.
Remove the four screws (two on each side) with a Phillips
head screwdriver.
3.
Remove the top cover and turn the unit
so
that its front
is
facing
you
with the wording orientated in the upright
position.
4.The four possible baud rates (1200, 2400,4800, and
9600)
are
changed
by
moving a plastic jumper used
to
connect
one
of
the
four speed connectors. The four speed connectors are located in
the upper right hand side
of
the unit. The four different baud
rates are printed on the printed circuit
card
next to each possible
connection.

INSTALLATION
SETUP at SwitcherKontroller Site
All controls for the Code Converter are located on the unit's front
panel. The front panel controls determine if the unit receives
Control Code and converts it to RS-232 or receives RS-232 and
converts it
to
Control Code.
This switch should
be
set
to
correspond
to
the selected baud rate.
At
1200 baud
-
4
Receivers may
be
controlled (position
4).
At
2400 baud
-
8 Receivers may
be
controlled (position 8).
At
4800 baud
-
12 Receivers may be controlled (position 12).
At
9600 baud
-
16,
20,
or
24
Receivers may be controlled
(positions 16,
20,
24).
Power
The
unit
is
set
to
a
%oo
baud rate when shipped.
The 1983 Code Converter
is
supplied with an
ON/OFF
switch.
The unit is turned ON by pressing the bottom of the switch
labeled
"1";
and turned
OFF
by
pressing
"0".
Power is supplied
via a pendant cord and plug. Verify that the unit is
off
(power
switch set to
"0")
and connect the pendant cord into the required
power
source.
See
Specifications
in
the back
of
this
manual.
DATA
OdOff
Switch
-
Set this switch to
OFF
initially. This places the
Code Converter off line. See the OPERATION section for
further
information.
Xmit/Rec Switch
-
This switch determines the direction
of
the
RS-232
data
flow.
When this switch is placed in the XMIT
position, it will receive Control Code from a Switcher/Controller
and transmit this
data
as
ASCII characters in RS-232 format.
When placed in the REC position, the Code Converter will
receive the ASCII characters via RS-232, and convert the
data
to
Control
Code
for the receivers.
RECEIVERS CONTROLLED
This switch selects the quantity of Receivers to
be
controlled by
the code converter, working in conjunction with the camera
section.
The position
of
the switch indicates the number
of
Receivers controlled and must correspond to the operational
baud
rate
(see
below).
Note: If the setting of the Receiver Controlled switch
is
greater
than the maximum number allowed by the baud rate, then only
the maximum number will be controlled.
For
example,
if
the
setting on the Receiver Controlled switch
is
set to 16, and the
baud rate is
4800,
then
only
12 Receivers will
be
controlled.
CAMERA
There are
two
switches associated with the CAMERA section of
the front panel. These two switches are BLOCK and START.
These switches are used
to
decide which block of
64
cameras the
control code will
be
used
for
and the starting camera number
of
the block.
Block
-This is a
10
position rotary switch. Positions one through
eight
are
used
to
select the block
of
cameras the code converter is
to be used for. The remaining two positions
of
the rotary are not
used. The selections are as follows:

SETUP At Distant Site (at Receiver)
All
controls
for
the Code Converter
are
located on the unit's front
panel. The front panel controls determine if the unit receives
Control Code and converts it to RS-232 or receives RS-232 and
converts it to Control Code.
XMIT/REC
Switch
-
Set this switch to REC. this places the
code converter in the receive mode.

OPERATION
Power
Switch
Place the unit into operation by depressing the side of the switch,
marked "1". See the Power section
on
page 1 for further
information.
Front Panel Indicators
Four
indicator
lights on the front panels of each code converter
indicate
status
and
operation. See below.
RS-232 OUT
-
This indicator, when lit, indicates data is
being transmitted to the link by the code converter in the XMIT
mode.
Code In
-
In the XMIT mode this light indicates the
presence of proper Control Code commands from the
Switcher/Controller into the code converter.
In
1600,
1650,
and
1700
systems, and from a
1680MG
Generator, the Code In light glows steadily whenever proper
Control Code is present. A flickering light may
be
an indication
that
the
B
and
W
wires of the Control Code line have been
reversed.
In 1995 and 2050 systems, it glows steadily only while proper
Control Code commands are being received from the Switched
Controller.
Code Out
-
In REC mode this light indicates that the proper
Manchester Control Code commands are being sent from the
code converter
to
a Receiver. It lights each time a proper Control
Code command is sent
out.
Control Code Transmission
When connections and setup are complete and the
communication link has been established between the code
converters, the link is ready to transmit Control Code.
To
transmit Control Code
perform
the following steps in order:
1.
Turn
on
both converters by depressing the
"1"
side
of
the
power switches on the left of the front panels.
2.
Move the DATA
ON/OFF
switch to
ON.
It is found
on
the
code converter
at
the Switcher/Conuoller (XMIT mode).
3.
Move the DATA
ON/OFF
Switch
to
ON,
found on the
code
converter at the distant site (REC mode). The RS 232 light will
now flash
on
both code converters when the Control Code
commands for the Receiver at the distant site are sent
from
the
Switcher/Controller. The Code-Out light on the code converter at
the distant site will flicker each time a word is sent to
a
Receiver
at
the site.
RS-232
