5. Route and connect the biphase connector as
shown in FIGURE 19.
P102 Biphase / RS-232 / RS-485
Figure 19 Wire Routing & Connection
6. DAISY CHAIN Wiring: Connect the (+) of each
of the cables by inserting them both into the (+)
terminal on the terminal block. Connect the (–)
of each of the cables by inserting them both into
the (–) terminal on the terminal block. Connect
the GND of each of the cables in a similar
manner. A 110 OHM RESISTOR MUST BE
CONNECTED BETWEEN THE BIPHASE (+)
AND (–) TERMINALS ON THE LAST CAMERA.
NOTE: Cameras connected to an AutoTracker cannot be
used in a daisy chain.
4.7.3
CONNECTING THE AutoTracker (Optional)
If the camera will be used with the Optional stand-alone
AutoTracker, connect the Power, Video, and Biphase data to
the AutoTracker first. Then connect the RS-232, Power, and
Video outputs of the AutoTracker to the camera. (Refer to
the AutoTracker INSTRUCTION BOOK for more details.)
4.7.4
CONNECTING THE RS-232 / RS-485 SIGNAL
CABLE
Not applicable if data input is via biphase codes (see
SECTION 4.7.2) or if connected to an AutoTracker.
1. Unplug the connector (FIGURE 18) from the
backbox.
2. Identify the RxD phase, TxD phase, and signal
GND wires.
3. Connect the RxD phase to the RXD terminal, the
TxD phase to the TXD terminal, and the signal
ground to GND terminal marked GND using a
flat-blade screwdriver (see NOTES).

NOTES:
1. The shield of the cable should be left unconnected.
2. If the internal switch #2 position is turned ON for
RS-485 operation, RXD functions as DATA (+), and
TXD functions as DATA (–).
4. Route and connect the RS-232 / RS-485
connector as shown in FIGURE 19.
4.7.5
CONNECTING VIDEO CABLE
Route and connect the video cable to the BNC connector
(FIGURE 19).
4.7.6
CONNECTING THE ALARM INPUTS AND
RELAY OUTPUT
If the Alarm Inputs or the Relay Output are being used,
connect them per FIGURE 20.
1. The Alarm Inputs must be connected to a dry
contact. To activate an Alarm Input, the dry
contact must change state between the
appropriate Alarm Input and the Alarm Ground,
Pin #8. For example, to activate Alarm Input #1,
the dry contact must change state between
Pins 7 & 8.
2. Alarm Relay Output Specification: 30VAC at
2 Amps; 60 Watts MAX.

NOTE: Push all excess cable through the conduit fitting or
strain relief bushing. This will ensure that excess wire in
the backbox will not interfere with the proper insertion of
the camera module.
