6.1 RS-485 Addressing and Connections 

 

The Philips ProBridge (CBR-PB2-PHILIPS) is not an addressable 
device and requires no user settings.  The device simply acts as an 

interpreter, translating the remote telemetry commands into a 
format useable by the P/T/Z controller. 

Each camera input, whether a fixed camera or a Pan/Tilt/Zoom (P/T/Z) unit, is 

connected to a Kalatel unit input.  The Kalatel unit has an RS-485 network 
address, and so does the P/T/Z camera receiver.  This address determines 

when the telemetry receiver responds to commands sent over the RS-485 
data line.  Consult the PTZ installation manual for specific instructions on 

setting these addresses. 

 

The CBR-PB2-PHILIPS can be used in conjunction with multiple 
Kalatel units, and/or keypads controlling the domes and the Kalatel 

units.  Since the ProBridge unit is a terminated device, care should 
be used when using this unit in a mixed application.   

 

The RS-485 network is a multi-drop wiring configuration of maximum length 
3,000 feet (1000 meters).  RJ45 cable and RJ45 connectors are used for 

most hookups (see the installation/connection diagram).  Some equipment 
manufactured by Kalatel may use flying leads, terminal blocks, or other types 

of connections. 

Most units have looping RS-485 network connectors.  Either socket can be 
used.  Do not use third-party RS-485 equipment without first consulting 
Kalatel Technical Support for information on compatibility with other Kalatel 

equipment.
