Communication Protocol

The MSX1616 contains three serial ports for communication. You can configure all three ports to communicate serially via RS-232, RS-422 or RS-485 standards by setting the DIP switches located at the rear of the unit to the appropriate setting.

Control Port 1

The baud rate is selectable from 1200 to 38,400. You can change the baud rate using the

$GYDQFHG menu option on the LCD on the front panel or via serial control using the [CPxbpsfd] serial command. Other adjustable parameters for port 1 include flow control (none or Xon/Xoff) and duplex (full or half). Parity, data bits, and stop bits are predefined and have no affect on port

1. The factory default communication parameters for the control port are:
