3.4 RS-232C Serial Port
The TMO2D contains a bidirectional, industry-standard RS-232C serial port which can be connected to a terminal or
computer that supports the RS-232C protocol (see The Outputs Menu on page 30.)
All keypad and most display operations can be performed remotely through this serial port.
