3. Configure the iRIM for LLGT.
Configuring the iRIM requires that you have a working network connection from a
maintenance PC to an installed iRIM. If you do not, see Intelligent Radio Interface
Module for Kenwood Radios
(P/N 025-9520) for connection information.
a. Open a web browser, such as Internet Explorer, and connect to the iRIM. The
default address is
http://192.168.0.133/
and the default password is
8206363
.
b. Click View or Modify Configuration .
c. Depending on the channel you need to configure, click
Channel A
Parameters or Channel B Parameters .
d. Set
Audio Level To Console
to
- 7
dBm (the default value).
e. Enable Guard Tone To Console On COR . This enables LLGT output from
the iRIM. Note there is no level setting for the LLGT; the iRIM always
generates LLGT at - 18dB below the Audio Level To Console setting. This
means that the iRIM shall generate the LLGT at a level of -25dBm if the iRIM
device generates an Audio Level To Console signal at a level of -7dBm by the
default parameter level setting.
4. Configure the channel with IntegratorRDPS.
a. Using IntegratorRDPS, make sure the channel is programmed as a Tone
channel with iRIM enabled (see Defining the Channel on page 269).
5. Adjust and test the configuration.
a. Key up a remote radio, but do not speak. This causes the low level guard tone
to be sent.
b. Adjust the UDCC Rx level pot so that the Rx test point reads -44.4 dBm (4.7
mV rms). This is a simple way to adjust Rx audio level when using an iRIM,
the resulting Rx level should be the same as if it was adjusted using the normal
Rx adjustment procedure (40% deviation is at the knee of the AGC).
6. Make some radio calls and confirm correct operation.
Note Step 3 only applies to the VOX+LLGT method of detection. For
VOX+COR, skip to Step 6 .
Note Step 4 only applies to the VOX+LLGT method of detection. For
VOX+COR, skip to Step 6 .
Note
Step 5 only applies to the VOX+LLGT method of detection. For
VOX+COR, skip to Step 6 .
