INTRODUCTION
The DHE Remote Base Interface (RBI-1) Adapts the Kenwood series TM-X21 and TM-X31 mobile radios to
several brands of Repeater Controllers. The RBI model 1 converts the serial data stream from the
controller and directly controls the Kenwood Mobile radio. All connections to the Kenwood radio are made
through the microphone jack. In the maximum configuration using a Kenwood TM-701 Dual Band Mobile
you can control Frequency, CTCSS encode On/Off, RF power level, Offset, Power On/Off, and Band. This
is all accomplished through the microphone jack.
The RLC-4 Format supports the following functions:
• Full frequency control, 4 ports/radios, and 4 bands.
• Transmitter power HI/MED/LOW
• CTCSS Frequency select, Encode on/off, Decode on/off.
• 20 and -12 Mhz offsets on 1200.
