1. General
The GP-1850/W series display unit consists of the following components.
Parts Name
MAIN board
ANLG board
PNL board
GPS
receiver
BEACON
receiver
LCD unit
Function
The board, heart of the unit consits of a CPU, ROM, RAM,
Card Interface circuit, a buzzer and a lithium battery. The
board generates high voltage for LCD backlighting.
The difference between A, B, E, and F is system program only.
The board includes power supply and echosounder circuits.
The board consists of key switches and backlight LEDs.
The receiver receives and processes satellite signal for
position fix.
The receiver receives radiobeacon DGPS to remove errors in
GPS position fix.
High voltage for LCD backlighting is derived from J101 on
MAIN board to Cold Cathode Fluorescent Light (CCFL) in the
LCD unit.
TX Output signal of echosounder circuit
50 kHz and 200 kHz transmitters in echosounder circuit on 14P0313B board outputs the
following signal to the transducer.
Range setting: 1200 m
50 kHz: 20 to 25 Vpp
Oscilloscope setting:
200 kHz: 27 to 32 Vpp
5 V/div, 200 us/div
(600 W)
Test points: Pins 8 and 10 on J2
(with XDR connected)

4. Replacing major parts
To replce the major parts, follow the steps below.
1. Place the unit on soft surface – face down. Remove all nuts (arrowed in Fig.2) and 12
screws (ringed) fixing the cover to the front panel. Then, lift the cover. Fig.3 shows
GP-1850/W series display unit with the cover removed.

3. Remove the shield cover, and unplug J2, J4 and J6 on MAIN board.
The MAIN board is battery backupped, so it is recommended that before removing MAIN
board, disconnect either lead of JP6 not to damage the components on the board by a
short circuit. With JP6 disconnected, the board is not battery backupped.

5. How to install DGPS beacon receiver
Refer to the installation manual.
6. Replacing lithium battery
To replace the battery with new one, follow the steps below.
1. Disconnect JP6 on MAIN board. See Fig.5.
2. Use a desoldering tool to remove the battery from MAIN board.
3. Solder the replacement battery onto the board.
4. Solder JP6.
CAUTION
1) Replace the battery only with CR2450-F2 ST2L (000-144-941).
2) Never short + and – sides of the cell.
3) The lithium cell may explode resulting in a fire or chemical burn if
mistreated. Do not recharge, disassemble heat, or incinerate.
4) Follow local ordinances or regulations for the disposal.

1) By using PC
The following explains how to upgrade the software by using a PC. The “up boot”
upgradation is carried out only when requested.
Before upgradation
The batch file “up_boot. bat” is designed for the use of COM2 port of the PC. When COM
1 port is used, the batch file needs to be modified by using a text editor application such as
Note Pad. The last number is changed from “2” to “1” when COM 1 port is used.
Uppg load. bin GPXXXX. 0 0 1 0 0 0 2
Procedure
1. Copy all files in EXE files to PC.
2. Connect the COM port of the PC to the DGPS port of the plotter.

3. Run “up_boot. bat” on PC. The message “TAEGET POWER ON” appears on the
display.
5. Turn on the plotter. You hear three beeps (pi pi pi) and the message “Execute STEP1”
appears.
6. Then a beep sounds and the message “Execute STEP2” appears. It takes about 5
minutes to complete steps 4 and 5.
7. When the message “Finish version up” appears, the upgradation of the boot software
is completed.
8. Turn off the plotter.
If the up-boot procedure fails, the plotter must be reset by downloading the software
from a master program card.
8. Run CTOOL_E.EXE on PC. The CTOOL_E.EXE creates following files.
Models
GP-1850/1850D
GP-1850W/1850WD
GP-1850F/1850DF
GP-1850WF/1850WDF
File name
1850e. BAT, CU1850e. BAT, LOAD. BIN,
UPPG EXE
1640fe. BAT, CU1850fe. BAT, LOAD.
BIN, UPPG EXE
9. Run either batch file, C1850 BAT or C185e.BAT according to the model to get the
binary file (Cxxxe.BIN).
10. Then, run either batch file, CU1850e. BAT or CU1850fe.BAT according to the model.
11. Turn on the plotter when the message “TARGET POWER ON” appears on the PC.
6
2) By using program master card
The following describes how to update the software by using the master card.
1. Insert Program master card into the slot.
2. Turn on the power. “NOW LOADING” message appears.
3. When loading is completed, the message “PLEASE REMOVE A CARD AFTER
POWER SUPPLY CUTS” appears on the display. Then, the power is automatically
turned off. If the power is turned off without the message, the program loading is failed.
Repeat above steps.
8. How to upgrade system program
The software is updated by following the procedure below.
1) By using PC
Take steps 8 to 11 in the previous section. The Navionics version program files do not
include a letter C.
2) By using program master card
The procedure is the same as the previous section.
