The HVBMAXPTZPIT Protocol Interface Translator (PIT) converts Honeywell's Maxpro serial command protocol to Honeywell’s VCL and Diamond Maxpro mode and Sensormatic’s (AD) PTZ protocol. The PIT has two serial communications ports. The RS422/RS485 "Slave" port connects to the master controller outputting MAXPRO-Net protocol. An RS232 to RS422 converter is required between the MAXPRO-Net controller and the PIT to convert the MAXPRO-Net data from RS232 to RS422. The RS422/RS485 "Master" port connects to the PTZ devices.
