Protocol Interface Translator (PIT)
The Honeywell Protocol Interface Translator converts BossWare serial command
protocol, to various protocols compatible with equipment from other manufacturers.
The PIT has two serial communication ports. The RS422/RS485 "Slave" port connects to
the BossWare communications loop and interprets the telemetry control messages. The
RS422/RS485 or RS232 "Master" port connects to the other manufacturer's equipment.
The PIT may be configured to operate in various modes:
•
In PTZ mode, the BossWare PTZ control messages are received on the "Slave"
communications port. Dependent on the DIP switch settings, these commands are
then translated to serial data packets, which are compatible with other
manufacturer's Pan/Tilt/Zoom telemetry receivers or integrated domes.
•
In device control mode, generic BossWare device control commands are received
and translated into data packets compatible with other manufacturer's VCRs,
Multiplexers, Quad's and the like.
•
In the Alarm Concentrator mode, alarm inputs and system outputs may be
connected via the I2C expansion port on the PIT. This allows for the connection of
up to 256 remote alarms into a system and also for up to 256 system outputs. In
device control mode, the PIT receives generic device control commands from the
system main controller.
