10.3 DATA Transmission (Digital Operation Modes)
DATA menu

Alternative Termination
of DATA Operation
The function DATA enables to send out signals which modulate the transmitter
by using following inputs:
0 dBm IN (microphone socket MIC-PTT pin 4, see Page 7 Tab. 6)
AUDIO DATA IN (J20 AUDIO IN/OUT pin 2, see Page 6 Tab. 4)
This is basically possible with all modes – where appropriate. Thus why it is
called „submode"
When pushing DATA button located in the cluster MODE:
DATA-LED will stay off.
DATA menu will be called up.
In case this softkey is activated (the softkey will be displayed inverse;
DATA-LED will turn on) the signal at the 0dBm input (MIC-PTT Pin 4)
will be transmitted when PTT is switched.
In case this softkey is activated (the softkey will be displayed inverse
as shown here; DATA-LED will turn on) the signal at the AUDIO
DATA IN input (J20 Pin 2+3/10) will be transmitted when PTT is
switched.
In case this softkey is activated (the softkey will be displayed inverse; DATA-
LED will not turn on) the signal at the AUDIO DATA IN input (J20 Pin
2+3/10) will be transmitted when PTT is switched by an external software
command (USB interface).
TX 0dBm, TX DATA and DATA Mike are only working alternatively.
DATA mode may be selected in all operating modes.
Only when DATA mode is selected a PTT signal can be fed through USB
interface (handshake signal).
In case the DATA softkey menu is displayed pushing DATA will only terminate
TX 0dBm or TX DATA modus.
If the menu is not displayed pushing DATA will call it up and a second push
will terminate the aforementioned DATA operations:
DATA-LED will turn off.
