SharkRF openSPOT3, User Manual, Page: 56 / 131

code, the outgoing call to the network will be automatically ended, so others won't be annoyed by hearing
your DTMF tones on the same reflector/talkgroup.
Special command/cross mode private call DTMF code : this code is used as the first character for entering a
control DTMF code, or starting a private call in cross modes. See more info at each connector's description , or
at the Control calls section.
Cross mode group call DTMF code : if a connector is active which supports group calls and C4FM cross mode,
then this code can be used to start group calls to the ID entered after this code.
If
Transmit RX confirmation is checked, then the openSPOT3 will transmit a short call confirmation after the
PTT is released on the C4FM radio.
If a call is received by the modem to the
Echo DGID , then the openSPOT3's built-in local echo service gets
activated. It will record the call and plays it back after the call is finished.
If the
Only receive DGID from modem checkbox is checked, then calls only to the specified DGID from
modem will be processed by the modem.
If the Replace DGID to modem enabled checkbox is checked, then the DGID in all frames received from the
network will be replaced with the specified Replace DGID to modem value.
If the
Replace DGID to net enabled checkbox is checked, then the DGID in all frames received from the
modem will be replaced with the specified Replace DGID to net value.
NXDN® settings
The modem will only process NXDN® calls with a matching Radio Access Number if it is set other than 0.
If a call is coming from a mode which does not have ID information (ex. C4FM), or the source ID is outside
the NXDN® ID range (0-65535), then the
Default cross mode source ID will be used as the source ID for the
call. This ID will always be used if the Always use this ID in cross mode checkbox is checked.
If you use a non-NXDN® network with your NXDN® radio, you can set this to your NXDN® ID.
If Advanced mode is enabled, the following settings show up:
If a call is received by the modem to the Echo ID , then the openSPOT3's built-in local echo service gets
activated. It will record the call and plays it back after the call is finished. Both private and group calls are
answered with a private echo call reply.
If a call is coming from a mode which does not have ID information (ex. C4FM), or the destination ID is
outside the NXDN® ID range (0-65535), then the
Default cross mode destination ID will be used as the
destination ID for the call. This ID will always be used if the Always use this ID in cross mode checkbox is
checked.
If the
Allow only IDs as cross mode callsigns setting is enabled, and the source callsign of a cross mode call
has no associated ID in the database, and also it can't be parsed into an NXDN® ID, then the call will be
ignored.
