Radio Transmitter Settings
VoIP to Transmitter Mode
determines whether the AudioMate 360r will allow two-way
audio flow or prohibit transmission entirely.
OFF disables the AudioMate 360r from keying the attached radio transmitter. Use to
prohibit transmission entirely in listen-only applications where the radio should never be
keyed under any circumstances.
Half Duplex will allow the attached radio to transmit on reception of audio packets from
the IP network while simultaneously blocking audio from the radio. Select this when
attached to a conventional radio.
Full Duplex will allow the attached radio to transmit on reception of audio packets from
the IP network without blocking audio from the radio. Select this when attached to a full-
duplex repeater station or trunked control station to send the talk permit beeps to the
remote end. This mode will double bandwidth consumption during times when the unit
is simultaneously sending and receiving packets.
ON will force the attached radio to transmit without blocking audio from the radio. Any
received audio packets will be sent to the radio transmitter.
PTT Polarity
sets the logic level required to key the attached radio. For radios requiring an
active low or ground signal on their PTT lines, select Active LO. For other types of keying
circuits select Active HI. Consult your radio technical manual to determine the proper
setting.
Transmit Pre-Emphasis Enable
will apply a 6 dB per octave high pass filter to the transmit
audio stream from the IP network to the transmitter audio of the attached radio. Check
the box to apply this filter or clear the check box to allow the transmitted audio to pass
unprocessed (flat audio). In general, if the transmit audio line of the AudioMate 360r is
connected to the microphone input of the attached radio, then leave this check box
cleared. If the audio is fed directly to the FM modulator of the radio, this check box should
be checked to enable pre-emphasis.
Transmit Gain
accepts a number from 0 to 63 representing 64 steps of attenuation or gain
in the audio path from the IP network to the attached radio transmitter. Level 0 represents
the lowest audio level while 63 represents the highest audio level. Follow the procedure
specified in your radio’s technical manual to set this to an acceptable level. The default
value is 31.
PTT Forced Release Timeout
prevents the attached radio from tying up the channel, such
as a stuck footswitch on a console on the IP network. The timer starts when the radio PTT
is asserted. If the timer expires during a transmission, the transmitter will be released.
Acceptable values for
PTT Forced Release Timeout
range from 0 to 25.5 minutes. Typically
this value is set between 1 and 3 minutes for practical LMR applications. Default is 0 which
disables this timer.
PTT Release Hang Timer
sets the time period between the end of the inbound IP network
stream and the release of the PTT signal by the AudioMate 360r. This can be useful if the
radio unkeys before all the audio has finished playing out of the buffer. Acceptable values
for
PTT Release Hang Timer
range from 0 to 25.5 seconds in increments of 0.1 seconds.
Default is 0 which disables this timer.
