COM2 (Data) Connections

Typically, the port (Figure 21) is used for connecting the radio to an external DTE serial
COM2
device supporting the RS-232 or RS-485 serial data format. The radio supports serial data rates
of 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous on-
ly).
Pin Descriptions; RS-232 and RS-485
Table 8 and Table 9 provide detailed pin descriptions for the
RS-485 modes, respectively.
