Changing Mobile Radio Parameters
Perform the following steps to make changes to mobile radio parameters:
Step 1 At the desktop, run the IPMN_INVADR by double clicking on the dial-up network
connection shortcut, as shown on the previous page.
Step 2 At the desktop, run the IPMessage Utility by double clicking on the IPMsg shortcut,
as shown on the previous page. The IPMessage window displays.
Step 3 In the left field type the mobile radio’s IP address and press ENTER.
Step 4 In the right field type a ? and press ENTER. A list of mobile radio configuration
parameters appears in the upper message window.
Step 5 In the lower message window type unlock=password (entering the appropriate
password) and press ENTER. This command unlocks the mobile radio’s Firmware
and grants the user authority to change mobile radio parameters.
1 WARNING! Do not change mobile radio parameters unless familiar with this
process. Changing a parameter to the wrong value may seriously affect the
mobile radio’s performance. Parameter changes should be limited to the IP
address, power output, channel number, and RX/TX frequencies.
Step 6 Enter appropriate commands in the lower window with parameter changes (see
examples to follow).

In the following examples, the frequencies are representative of the IPM4.
Replace with the appropriate frequencies if dealing with an IPM1 or IPM8
EXAMPLE 1 SCENARIO
The transmit power output is too high. The client was authorized 25 Watts. The mobile radio configuration list
shows TX Power=200 (this does not mean 200 W).
Parameter Change Command:
In the lower message window, type the following command, then
press ENTER.
TX POWER=150
Send test messages, measure the RF power output, and reenter the command with increased or decreased
values until 25 watts is achieved. The mobile radio is designed for full power use. Please consult IPMN Customer
service if your needs are going to be at a lower power output. TX power is not guaranteed to produce any user
selectable power level.
EXAMPLE 2 SCENARIO
The mobile radio was set for the wrong RX frequency. The client was assigned 471.5500 (RX), and 474.5500
(TX). The mobile radio configuration list shows TX Freq=474.5500, and RX Freq=471.0000.
Parameter Change Command:
In the lower message window, type the following command, then
press ENTER.
FREQUENCY=0,474.550000,471.550000
NOTE: This programs channel 0. The trailing zeros (0) are not required.
