PURPOSE
To configure the RPM4-E-DWT COM1 and COM2 communication ports. To test COM1 and
COM2 communications. To select the remote programming communications format.

PRINCIPLE
The RPM4-E-DWT has two RS-232 communications ports referred to as COM1 and COM2.
COM1 is for communicating with a host computer (see Section 4), and COM2 is reserved for
communicating with an external device (e.g. an RPM4-E-DWTx, a multimeter, etc.). The
ports’ settings can be viewed and changed using
[SPECIAL] , <2remote> .
RPM4-E-DWT has two remote communications formats, classic and enhanced (see Section
4.3). The active format can be selected.
A self test is supplied for RS-232 communications. The self test allows verification that the
RPM4-E-DWT RS232 ports (COM1 and COM2) are operating properly and that a valid
interface cable is being used.
