    COM2 CONNECTIONS connector (Figure 10) is used to connect the radio to an COM2 external DTE telemetry device that supports the EIA/RS-232 or EIA/RS-485 (balanced) format, depending on how the radio is config- ured. The radio supports data rates of 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous data only).
