iRIM Configuration Reference
48
025-9623 D3
Parameters Specific to iDEN Handheld
The iDEN-specific parameters are available on both the
Channel A Configuration Page
and the
Channel B Configuration Page
, and may be set independently for each channel.
iDEN-specific parameters are only available if the radio type for that channel is set to
iDEN Handheld
.
Use Hardware Ptt
This parameter determines whether the iRIM will use serial protocol commands (when
this parameter is disabled) to key the iDEN handheld radio or if it will generate a
hardware PTT signal (when this parameter is enabled) to make group calls. Use of this
function requires that the radio be interfaced to the iRIM by means of the 709-8061 cable
provided by Zetron. The default setting for this parameter is
Disabled
.
Note
Changing the state of this parameter from Disabled to Enabled
will also cause a change in the default level setting for the audio
levels
To
and
From
the radio.
Audio Level To Radio (dBm)
Audio Level To Radio
specifies the level at which average voice audio from the iRIM is
sent to the radio. A 1 kHz tone at this level will be sent over the air at 60% channel
deviation. This level is expressed in dBm. A value of 0 dBm is equivalent to 0.775
VRMS. The default level setting should not need to be changed; however, it is dependent
on the state of the
Use Hardware Ptt
parameter.
Disabled =
-8 dBm
Enabled = -20 dBm
Audio Level From Radio (dBm)
Audio Level From Radio
specifies the level at which average voice audio from the radio
reaches the iRIM. A 1 kHz tone at 60% channel deviation received from the radio will
reach the iRIM at this level, which is expressed in dBm. A value of 0 dBm is equivalent
to 0.775 VRMS. The default level setting should not need to be changed; however, it is
dependent on the state of the
Use Hardware Ptt
parameter.
Disabled =
-11 dBm
Enabled = -20 dBm
Talkgroup List
The Talkgroup list is available on both the
Channel A Configuration Page
and the
Channel B Configuration Page
, and may be set independently for each channel.
Talkgroup List
is only available if the radio type for that channel is set to
iDEN
Handheld
.
