* This is the acknowledgement response time used by the older versions of the AD2083. Also note that setting
changes requires cycling of power to the unit.
Alarm Contacts and Dome Type Setup
The S6 DIP switch is used for selecting the number of alarm switch contacts that can be configured for each
dome. This switch also selects the dome type for each of the four groups of connectors. These switch positions
must be set to OFF. Table 4 shows the S6 switch position settings for these selections.
Note
Each SpeedDome, SpeedDome Ultra, and SpeedDome Optima accepts a maximum of 4 alarm contacts. The
SpeedDome LT does not accept any (zero) alarm contacts.

Connections
Interface Connectors
Eight 12-pin connectors on the rear of the AD2083-02C Code Distributor panel are used for transmitting and
receiving codes with domes and J-boxes. The transmit (T) and receive (R) signal positions are labeled on each
connector. Each connector is supplied with a mating screw terminal connector (see Figure 4). Simplex only
requires connection to transmit.
Figure 4 – Typical Mating Screw Connector
Control Code Connector
The upper right connector on the rear of the AD2083-02C Code Distributor is a 12-pin connector. This is used to
receive Control Code signals from 1650 or 2150 switcher units (B, W, and S lines) and to provide access to an
internal Form C alarm relay. When the AD2083-02C receives an alarm from any SpeedDome, the internal alarm
relay closes. This relay can be used for turning accessories (VCR, etc.) on or off via its Normally Open (NO) or
Normally Closed (NC) terminals. The mating screw terminal connector is shown below (see Figure 5).
Figure 5 – Control Code Mating Connector
Connections on the above 12-pin connectors are easily made by inserting signal and ground wires into the slots
of the Pin1 mating connectors and tightening the hold down screws. When all wires have been connected, insert
the 12-pin mating connectors into the rear panel.

Data Line Connectors
Two DATA LINE BNC connectors are provided on the rear panel, labeled IN and OUT. The IN is used to receive
control codes from the 1995 or the 1996/1024 CPU of the 2050 systems. The OUT is a loop through connection.
If this device is the final device in a daisy chain, the BNC must be terminated in 75 ohms. Use RG-59U video
cable for all connections.
Note
When 1995 or 2050/1024 systems with existing B/W/S Control Code interfaces are used, they can be
connected to the AD2083-02C Control Code Connector, as shown in Figure 5.
RS-232 Connectors
Two RS-232 connectors on the rear panel, labeled INPUT and OUTPUT, are provided for alarm interface
connections. The output port is for connection to the switcher/control system alarm input ports or for cascading to
another AD2083-02C unit's input port or a 2096 Alarm Interface unit. The baud rate is set for these ports as
shown in Table 2.
The RS-232 connectors are 8-pin modular type RJ-45 connectors. The pin-out definitions for the two connectors
are shown in Table 5.
Table 5 – RS-232 Connectors Pin Definitions

7 GND GND Shield
Remaining Pins - No Connection
The AD2083-02C connects to switching systems with a modular cable 6003-0047-02, when distances between
the units are no further than 7 feet apart.
Note
The pin definitions as listed require modular cable 6003-0047-02, or similar (that is, a cable that inverts the
connections).
For connection to switchers where the distances exceed 7 feet, a modular cable with a wall-mount 8-pin Terminal
Block, Figure 6, is provided for plug-in to the rear panel connectors. The pin definitions for this block are the same
as in Table 5. See Appendix for typical connections.

Operation
Power Sources
DO NOT CONNECT THE EQUIPMENT TO A POWER SOURCE UNTIL READY TO "POWER UP''. Make all
connections to the AD2083-02C code input and relay connections and set the DIP switches prior to power up.
The AD2083-02C Code Distributor does not contain an On/Off Switch. The socket outlet shall be located near the
equipment and shall be readily accessible. The 120 V units are supplied with a pendant 3-wire cord and plug for
mating to the primary source outlet. The 230 V units are supplied with a Euro style IEC 320 type inlet. A suitable
detachable cord should be connected between the IEC 320 inlet and the power source. The cord should be
connected between the IEC 320 inlet and the power source. The cord should conform to all national and local use
code requirements. A green POWER LED indicator located on the rear panel illuminates when power is applied.
Code Distributors are available in two models, depending on the power source to be used:
AD2083-02C 120VAC, 50/60 Hz
AD2083-02C-1 230VAC, 50/60 Hz
The AD2083-02C unit has fuse power protection. The fuse sizes for replacement are:
AD2083-02C 120V -250V, SB, 0.3 A, 5 x 20mm
AD2083-02C-1 230V -250V, T, 125 mA, 5 x 20mm
Operating Indicators
When the unit is receiving valid code, the green CODE LED, on the rear panel, is illuminated. The LED stays lit
for 5 seconds after code is removed. If this LED does not light, a problem in the unit or its interconnection may be
indicated.
If an alarm input is activated, the green ALARM LED illuminates, and the alarm relay closes. The ALARM LED
remains illuminated and the alarm relay remains closed for 10 seconds after the alarm input is removed.
Controlling Receiver Features
The AD2083-02C supports the transmitted codes for all SpeedDome LT, SpeedDome, SpeedDome Ultra,
SpeedDome Optima, and SpeedDome Optima LT models. This includes full Pan, Tilt and Lens control, 60 presets
per receiver, and 4 special Console to Dome commands per Speed Dome. The special Console to Dome
commands are: Reset Iris, Increase V-Phase Delay, Decrease V-Phase delay, and Reset Dome. Pattern
programming features of the domes are also provided.
The AD2083-02C also supports alarm contacts. The American Dynamics Start Alarm and Stop Alarm commands
are transmitted via the RS232 output port. The alarm contact number is based on the American Dynamics real
camera address and the number of alarms per dome selected. When an alarm is received, an internal relay
closes and the green alarm LED illuminates. The alarm reading is an asynchronous operation, working on a first-
in first-out basis.
