RS485 port connection (only hybrid models)
Use the RS485 connector to connect Bosch, Pelco-P or Pelco-D controllable cameras to the
unit for pan, tilt, and zoom control. RS485 is a single-direction protocol; the PTZ device can’t
return any data to the unit.
Since RS485 is disabled by default for each camera, you must enable the PTZ settings as
follows:
1. Connect a suitable cable to the RS485 connection on the DVR rear panel.
2. Connect the other end of the cable to the appropriate pins in the camera connector.
3. Follow the instructions in the Operation section of this manual to configure the camera
for PTZ control.
The Bosch protocol is supported with the following baud settings:
– 9600 baud
– 8 data bits
– 1 stop bit
– no parity
– no flow control
