Basic Serial Interface Operation <SERIAL INTERFACE NOT IMPLEMENTED>

Refer to the Rear Panel Controls and Connections

section for serial interface connection

details. Serial commands are detailed in the Serial Commands

Section.

Serial interface protocol is RS-232, with 8 data bits, 1 stop bit, no parity. The baud rate is

selectable, 19200 Baud or 9600 Baud (see below). The factory default baud rate is 19,200

baud.

Connect the R301’s RF output to a 50-Ohm, 500 Watt resistive load, Impedance

Matching network, processing system or other suitable load before enabling AC

mains Power.
