Pin Descriptions—RS/EIA-232 Mode
Table 27 lists the
DATA connector pin functions for radios configured to
operate in RS/EIA-232 mode.
NOTE: The radio is hard-wired as a DCE in the EIA-232 mode.
Table 27. DATA connector pin descriptions—RS/EIA-232
Pin
Number
Input/
Output Pin Description
1 OUT DCD (Data Carrier Detect)
A “high” indicates hopping synchronization.
2 OUT RXD (Received Data)
Supplies received data to the connected device.
3 IN TXD (Transmitted Data)
Accepts TX data from the connected device.
4 IN Sleep—A ground on this pin turns off most circuits in a Re-
mote radio, including transmit, receive, modem, and diag-
nostic functions. 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 (Re-
mote Units Only)” on Page 59 for details.
5 IN Signal Ground—
Connects to ground (negative supply potential) on the ra-
dio’s PC board and chassis.
6 OUT Alarm Output—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 ASENSE [HI/LO] Details, page
29 for further information.)
7 IN RTS (Request-to-Send)
8 OUT CTS (Clear-to-Send)—Goes “high” after the programmed
CTS delay time has elapsed (DCE), or keys an attached ra-
dio when RF data arrives (CTS KEY).
9 -- Reserved for Special Uses (Do not connect)
