Using the P4800 with AMX / Crestron Systems
Wiring
The P4800 uses a standard 7 wire RS-232 port for control. Crestron and AMX controllers use 5 wire RS-232. In order to
use a P4800 with Crestron or AMX, a custom cable will need to be built. The following diagram shows the cable. For a 5
volt supply, the resistor should be 1kohms.
All wires are straight through. The 9 pin connectors have numbers stamped on them. Follow those stamped numbers for
the pin out. Connect the RX, TX, GND, RTS, and CTS to the five wire RS-232 port on the control unit. The P4800 requires
a voltage of 5 to 12 volts on the DTR line. This voltage tells the microprocessor to accept any data that it receives on the
TX line.
