3.3.1.3 Serial Port Connections
The serial interface (Serial Port A) on the main logic card supports RS-232C and RS-422/RS-485
communications. The Aux Serial, J1 on the Applicator Interface Card, supports RS-232C only (see
Appendix D for details).
Serial port settings for baud rate, word length, word parity, stop bits, and handshaking protocol are menu-
selectable and must be configured to match the host’s port settings; see Section 4.2.6.
