Replacing Main Unit
Main unit information
Method of confirming “Original Main unit” and “Service
Main unit”
Note:
• The 0
Ω
resistor (R1, R2, R3) is used to differentiate the
destination with a visual check. These are not connected
with any PCB pattern; they are specifically for production
control. There is no need to change the mount of these re-
sistors.
• There is no difference between the schematic diagram of
the Service Main unit (XC1-0341-82/XC1-0341-83/XC1-
0370-12/XC1-0370-13) and the schematic diagram of the
original Main unit (XC1-0341-80/XC1-0341-81/XC1-0370-
10/XC1-0370-11). (R1, R2 and R3 are connected with
GND (ground) only.)
Supplied Accessories of “Service Main unit”
”Service Main unit” Data
The following data is written on the service unit:
After Changing the PCB
(1) After changing the printed circuit board, write the up-to-
date Firmware following the instructions in the “2.2 RE-
ALIGNMENT - 2.2.6 Firmware Programming Mode”.
• Write the Firmware in accordance to the Market. If you
write different Market Firmware, there are times com-
munication with the FPU is not possible.
(2) Using the KPG-D1/D1N, select your desired item (Model
Name and Frequency) from the Model> Product Infor-
mation menu, then use Program> Write Data to the
Transceiver to write the FPU data (PC Programming
mode). When writing to the transceiver, a Warning Mes-
sage, corresponding to the item selected, appears. Click
[OK] to continue writing the data.
(3) Enter Program> Test Mode, then adjust the various ad-
justment data (PC Test Mode) as described in the "SEC-
TION 4 ADJUSTMENT".
(4) Attach the new labels corresponding to the new printed
circuit board. (Refer to the images below for label place-
ment.)
(5) If necessary, write the FPU data used by the customer
with the KPG-D1/D1N.
Note:
• When using the ESN Validation function of NXDN Trunk-
ing, the NXDN ESN number changes when the circuit
board is changed (the number is written on the circuit
board); the NXDN Trunking System cannot be accessed.
Use the KPG-110SM on the NXDN Trunking System side
to reprogram the NXDN ESN number.
• When a new printed circuit board is used, the KENWOOD
ESN changes, as does the Transceiver Information dis-
play of the KPG-D1/D1N, but this does not have any effect
on the operation of the transceiver.
• If changing to the original ESN, please contact our service
center.
• KPG-D1N can't be used for E, E2 types.
