Connectors
364 Manpack Transceiver 2110 series Reference Manual
The operating parameters of the serial data connector are set up in the RS232 Mode and
RS232 Speed entries in the Control List.
The operating parameters can be set to the following:
System power (A rail protected)
System power is switched off when the transceiver is switched off.
Tx audio input
Audio input from external equipment, for example, data modems, is connected between
pins 5 and 15 and is a balanced floating input. The input signal should be nominally
1 V p–p and not exceed 3 V p–p.
System audio output
This supplies raw audio (no Easitalk) from the receiver at a level of 1 V p–p when the
RS232 Mode entry in the Control List is set for your particular modem, that is,
Fax/Data, Pactor 1, HAL/Clover, Modem Slow AGC, or Modem Fast AGC.
When the RS232 Mode entry in the Control List is set to None, CICS, GPS or
3033/RTU–292, the audio output is determined by the Easitalk setting on the handset. It
is unaffected by the volume control.
NOTE
If these entries are not displayed in the Control List, they may have been
hidden at user or admin level. For more information on displaying hidden
entries see page 131, Hiding and showing information.
