Manpack Transceiver 2110 series Reference Manual 363
Morse input
When a ground is detected on the morse input, the transceiver generates a morse tone on
air. This functionality is typically provided with a morse key.
PTT
This function puts the transceiver into transmit mode and enables the audio transmit path
via the GPIO connector (pins 5 and 15).
Q line
The Q line switches the transceiver between data and voice modes, and stops the
transceiver from scanning. When the transceiver is in data mode, it uses slow AGC and
an ALC that is suitable for data transmission.
If you want to use a data modem with the 2110 Manpack Transceiver, set the RS232
Mode entry in the Control List to Modem Slow AGC or Modem Fast AGC, as
required for your modem (see Table 31 on page 228 and page 363, Serial data).
Serial data
The serial data (RS232) connector can be used for controlling and monitoring the
transceiver, programming the transceiver settings, and sending and receiving message
calls.
The serial data connector may be used in a number of modes:
When in CICS mode, the interface accepts any of the CICS commands as detailed on
page 403, Operating the transceiver from a computer.
When in GPS mode, the interface accepts and processes GPS receiver input sentences
(RMC, GLL, and GGA) defined by NMEA format 0183 V2.00. If the interface detects
the RMC sentence, it ignores all data derived from any other type of sentence as the
RMC sentence guarantees data validity via checksums.
None to be used when no external RS232 device is connected to the
transceiver
GPS to receive GPS position information
CICS to control and monitor the transceiver
Fax/Data to be used with a 9001 or 3012 modem
3033/RTU–292 to be used with a radio/telephone interconnect unit
Pactor 1 to be used with a single-tone FSK Pactor modem
HAL/Clover to be used with a multi-tone PSK HAL/Clover modem
Modem Slow AGC to be used with a multi-tone modem
Modem Fast AGC to be used with a non-Codan single-tone modem
