4.2 COM2 Connections
The COM2 connector (Figure 11) is typically used to connect an
external DTE telemetry device to the radio, which supports the
RS-232 or RS-485 (balanced) format, depending on how the radio
is configured. The radio supports data rates of 300, 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous
data only).
The COM2 connector mates with a standard DB-9 plug that is
available from many electronics parts distributors.
4.2.1 Pin Descriptions—RS-232 Mode
Table 2 provides pin descriptions for the connector when operating
in RS-232 mode. For RS-422/485, refer to the Reference Manual.
NOTE: The radio is hard-wired as a DCE device.
The chart below shows a top-level view of the transceiver’s menu-
system. For detailed menu descriptions, refer to the SD Reference
Manual.

3INTXD (Transmitted Data)—Accepts TX
data from the connected device.
4INSleep Mode Input—Grounding this pin
turns off most circuits in a remote radio.
This allows for greatly reduced power
consumption, yet preserves the radio’s
ability to be quickly brought on line. (See
Using the Radio’s Sleep Mode” for details.)
5--Signal Ground—Connects to ground
(negative supply potential) on chassis.
6OUTAlarm Output (DSR)—An RS-232
high/space (+5.0 Vdc) on this pin indicates
an alarm condition. An RS-232 low/mark
(–5.0 Vdc) indicates normal operation. This
pin may be used as an alarm output. (See
Reference Manual.)
7 IN Reserved.
8 OUT Reserved.
9 -- User I/O for special applications, not
normally used.
