Default SEATALK VS. NEMA 0183 CONNECTIONS

:I JUST BOUGHT A NEW SYSTEM FOR MY BOAT. RAYMARINE C-120, GPS 125 ANT. AND THE DMS 300 SOUNDER. AND TRANSOM MOUNT TRANSDUCER. AND NOW I'M
INSTALLING ALL OF THIS MY SELF. I WANT TO TIE THE SYSTEM INTO MY NEW UNIDEN UM-525 USING THE NEMA 0183 PROTOCOL.
RAYMARINE WIRING DIAGRAMS ARE NOT TOO CLEAR ON THIS, ALL I NEED TO KNOW IS WHERE TO CONNECT THE GPS TO THE C-120 INPUT. AND THEN THE OUT PUT IS CONNECTED TO THE UM 525 AND HOW THIS IS ALL DONE? I DON'T WANT TO USE THE SEATALK PROTOCOL AS THE UM525 IS NOT CLEAR ON HOW TO USE THE SEATALK IS A GPS IN PUT AS A MATER OF FACT UNIDEN INSTRUCTIONS STINK ON THIS ALSO WHAT'S WITH THE TWO ANT. INPUTS ON THE BACK OF THE 525 I ONLY NEED ONE WHAT'S THE OTHER ONE FOR? ANY HELP OUT THERE WOULD BE APPRECIATED THANK YOU " DIGIMOOSE."

The Uniden UM-525 rear panel connector marked "External" is intended for use with an external antenna for their 2.4-GHz wireless remote control/microphone WHAM-4 accessory. This is explained on PAGE 2 of the owner's manual. There are also mentions and references to this on PAGE 15 and PAGE 37.

It looks to me like all of the documentation provided with the UNIDEN UM-525 the Raymarine C-120, and Raymarine 125 GPS sensor is quite comprehensive and thorough, and it should answer all of your questions regarding how to interconnect and configure these devices.

Connect the RS125 as per the instructions that came with it for the Seatalk configuration (5th page, HERE: http://www.raymarine.com/raymarine/S...81247_3www.pdf )

Connect the YELLOW nmea+ and BROWN nmea- (C120 installion guide, pg 29 : http://www.raymarine.com/raymarine/S...es/87020-3.pdf )wires to the WHITE nmea+ and YELLOW nmea- on the GPS/External speaker Cable on the Uniden ( pg 12 HERE: http://www.uniden.com/pdf/UM525om.pdf )

If this is seeming like a really complicated job, you might consdier hiring a pro to come in and make the final connections after you have it all installed.

Just went through this same installation with a C-80 set up. What I found confusing was the NMEA out it is not clear from the 125 sheet that it does not come from the GPS unit but from the display. The 125 is wired to a Seatalk pigtail (flat plug). Any other NMEA 0183 device is wired to the NMEA pigtail (round plug) Other devices get GPS info through the display.

Digimoose - first of, unless you are SHOUTING, please hit your caps lock key to turn off all caps.

Connect the GPS antenna to the C120 via SeaTalk. ONLY. That will keep your NMEA in and out available to connect to your UM525 radio.

prodigalson had it half right. He told you to connect the NMEA out from the C120 to the NMEA in on the radio. In order to be able to display received DSC position reports on your C120, you also need to connect the NMEA out of the radio (orange and green) to the NMEA in on the C120. The radio NMEA out + (green) should be connected to the C120 NMEA in + (white), and the radio NMEA out - (orange) should be connected to the C120 NMEA in - (green).

This gives your radio and chartplotter full DSC functionality - the capability to transmit and receive positions via DSC, and to have those positions display on your chartplotter. If you get an autopilot in the future, you will need to make a minor modification (i.e. install a multiplexer). But don't worry about that now.

Good luck, and please let us know how it went.

I don't know the C80/c120, but in my Garmin 3010 I had to turn on some NMEA sentences in advanced set up to get the DSC in/out to work on my UM525.

marinerjoe; thank you for the instructions {sorry about the cap key} So what your saying is the cable
from the gps antenna goes straight from the ant. to the c120 sea talk {flat plug} 5 wires to 3 wires and use sea talk input not the nmea 0183 input . yes?

and the out put from the nmea 0183 {round plug 5 wires } goes to the un525 gps/spker input cable.
do I HAVE THAT RIGHT. ???? YES?

Digimoose,

You have it correct. You need to look at the wiring diagram for the GPS antenna, and connect the three SeaTalk wires to the SeaTalk (flat plug connector) on the C120.

Connect the NMEA connections from the C120 (using four wires) to the NMEA connections on the UN525. That will give you the NMEA in and NMEA out connections that will provide position data from your C120 to the radio, and received DSC position reports from the radio to your C120.

Also - go to the Raymarine website and download the version 4.25 update and apply that (via a flash card) to your C120. That will give you MANY enhancements and fix a couple of bugs.

Digimoose,

You need a card reader/writer to plug into a USB port. You can get them at any office supply place or computer place.

Also - do not use your chart chip. Buy a separate one. It doesn't need to be big.

marinerjoe;

sorry I took so lone to get back to you: That card reader/writer stuff sent me looking I didn't know it existed.
Did you know that their is about 15 different kinds of flash cards out there.
with all levels of memory in them. sandisk has compact flash cards type 1 and type 2 [FC TYPE}. SOOO!!!
What type and how much memory? and not to speak of reader/writer device its self that's got to be a whole new industry. digimoose.

digimoose - if you didn't find the other thread, all you need is a small (I use a 32 meg) card. Small ones may be hard to find. I don't know about type 1 or type 2, but if you go to the Raymarine site, they have some recommendations.

Joe
