1.SERIAL INTERFACE
a.RS232
The standard serial interface applicable to PP4000S is RS232. The communication protocols in RS232 are: 19200 bps, none parity, 8 data bits, 1 stop bit. These settings are fixed, not for change. The RS232 connection is done through a 9 pin D sub female connector with following pin assignments:

b.RS422
RS422 is the serial interface applicable to PP4000B. Similar to RS232, the communication protocols in RS422 are: 19200 bps, none parity, 8 data bits, 1 stop bit. These settings are also fixed and not for change. The RS422 connection uses the same 9 pin D sub female connector used in RS232 with following pin assignments:
