Connection to the P3 Port
IMPORTANT:
The drive MUST be earthed. Failure to do so could damage your communications ports.
The port is an un-isolated RS232, 19200 Baud, supporting the standard EI bisynch ASCII

The P3 port is located under the terminal cover and can be used for pc configuration or to remote
mount a RS232 keypad.
