Transmitter Programming
Transmitter programming is performed with the PC-based Radio Service Software (RSS). A
Daniels Radio Programming Interface Module (RPIM) is used with a special programming cable to
connect the serial port of an IBM compatible computer to the Digital I/O port on the front panel of
the Transmitter module. The RSS runs under Microsoft Windows 3.1 and Windows 95/98, and
allows the Transmitter to be programmed for operating frequencies, CTCSS and DCS signaling,
and modulation type. Analog test modes may be selected by the Radio Programming Software, as
well as test modes specific to Project 25 digital operation, such as Bit Error Rate testing.
