This is a nice piece of gear, but I am afraid you are going to need the help of a service department that can service JRC gear. I believe you are going to need a hard disk with info. It should have come with radio.

To extend the antenna of your Jlu 121Potter, you need coax cable. You can follow the general system diagram which is in the manual to attach the extended antenna.
You can also follow "http://www.c-trak.net/ctrak/Downloads/JRC/GPS_Plotters/JLU-121/JLU-121b.pdf". for more information.

Hope this will help you. Good Luck.

This device if the manual is right uses an RS232 connection, what you are goiung to look for is a nine (9) pin connection it will look similar to your VGA connection on your computer. Do not connect the cable to your VGA connection, the nine pin connector will connect to the gps unit and the other end of the connector will connect or at least should connect to your computers com1 one connection or maybe the usb connection not sure. Should note that this unit has been dicontunued and the only manuals i could find were in Japanese which i don't speak, but that should be your connection.

Hope this helps

I have the service manual for this GPS and it doesn't list the wire colors directly for the plug. This much I'm sure of:
RED-12 VOLTS (+)
BLACK-GROUND (-)
GREEN IS COMMON AND HOOKS TO CHASSIS OF GPS
THAT LEAVES THE BROWN AND YELLOW, BASED ON STANDARD DIN WIRE COLORS THE YELLOW IS LIKELY GPS OUPUT. HERE IS THE LINK TO THE SERVICE MANUAL. IF YOU OPEN UP THE UNIT THE WIRE COLORS SHOULD BE PRINTED ON THE CIRCUIT BOARD THAT THE PLUG IS ATTACHED TO.

Hi I do NOT think that you can connect this unit directly to a PC? It can indeed be connected to "Other" JRC devices, GP. Chartplotter etc, via a special connection box. However I have been unable to find any way to do as you wish?
I have searched for a, any, manual however I have been unable to find any.
My advise is to contact JRC first, and ask them for the details of what you need to know, perhaps they also can supply you with a manual too if you ask? Weblink below for your convenience.

There is a seal on the antenna scanner shaft, just below the seal there are two bearings, thou the antenna are enclossed moisture still get inside and get to these bearings. Try and get a small amount of wd40 on the bearings, if not, you will soon begin to see false echoes on the screen because the motor on the scanner or antenna will begin to work harder causing a drag causing these echoes. Good luck.

JRC GPS | 770 views | 4 helpful votes


It appears to have a computer interface,It uses an RS232C Interface, a small D9 Socket on unit, you need a specially wired cable, to talk to your unit, with GPS software, it sends out NEMA codes to the PC. You also need driver, and software, software at the least. www.jeppesen.com/documents/.../FullCompatabilityListAug09.pdf software compatibility list above.

I looked but couldn't find a manual...
