Installation involves connecting an LTC 8784/60 RS-232 to Biphase Converter to the male DB-9 COM1 port on the DS and then wiring the camera to the converter.


  • Installing Philips G3 AutoDome on an DS
    To use a Philips G3 AutoDome camera with an DS, you must connect a RS-232 to
    Biphase Converter from Philips (model LTC 8784/60) to the com port on the DS, and then wire the
    camera to the converter. This procedure is described in the following sections.
  • Philips G3 AutoDome: Connecting the RS-232 to Biphase Converter to the camera.
    To connect the RS-232 to Biphase Converter to the AutoDome camera, connect the S, +, and – pins on
    the converter’s terminal block to the Signal Ground, Code+, and Code– pins on P102 of the camera
    mount (see Table 8 and Figure 11). Drawing not to scale.

  • Philips G3 AutoDome: Connecting to the DS.
    Figure 11 illustrates the connection points between the DS and the camera. The cable connecting
    the RS-232 Biphase Converter to the DS is provided by Philips. (Drawing not to scale; DS
    drawing may not match your particular DS model.)

  • Philips G3 AutoDome: Selecting a Baud Rate
    On the camera mount, you must set S105 to a 9600 baud rate. To do this, set the S105 switches on the
    bottom of the dome drive or camera to the settings shown in Figure 12 (ON=switch up; OFF=switch


  • Philips G3 AutoDome: Selecting Addresses
    Each AutoDome camera connected to a DS must have a unique physical address from 1 to 32; on
    DVX series systems, the address must match the video input number the camera is connected to on the
    DS. To select an address, use the S101 to S104 thumbwheel on the camera (see Figure 13).
    Remember to terminate the final camera in each chain by applying the termination resistor to the
    Code+ and Code– pins on P102 of the camera mount.
