10 Fiber Optic Module with an RS232/RS422 Controller
(AUTODOME VG5-600 Camera Models ONLY)
This chapter applies only to AUTODOME cameras.
An AUTODOME camera with a fiber optic module is prewired to operate with Biphase signals
only. This section describes the procedures necessary to control a VG5 Series camera fitted
with a fiber optic kit using an RS-232 controller or a Pelco® RS-422 controller.
To control a VG5 Series camera from an RS-232 or from a Pelco RS-422 controller, you must
run control wires from the controller to an LTC 4629 head-end fiber optic module.
10.1 Connecting to an LTC 4629 Head End Data/Video Transceiver
1. Connect the RS-232 cable (TxD from the controller) to the RS-232 RxD port (pin 1) of the
LTC 4629.
2. Connect the ground wire of the controller to Pin 2 on the LTC 4629.
10.2 Configuring the VG5 AUTODOME Camera
1. Disconnect the power to the VG4 power supply unit; then open the unit.
2. Remove the green Serial Communications wire from the P106 connector.
3. Remove the 100 Ω resistor across the C+ and C- pins.
4. Cut the five wires from the green Serial Communications wire mating connector.
Ensure that the insulation covers each wire to avoid wires from touching.
5. Cut back the insulation on the blue (ground) wire and on the green (RxD) wire enough to
be able to connect these wires back into the P106 connector.
6. Connect the blue (ground) wire to the C- pin on the P106 connector.
7. Connect the green (RxD) wire to the C+ pin on the P106 connector.
