Question about Raymarine RL70CRC GPS Receiver

1 Answer

Raytheon RL70C and/or RL70CRC

I do not have USB capability between these 2. I do have a good RL70CRC that will communicate with another RL70 but not to these 2. I am very adept at electronics but the only schematics I can get are simplified and do not got to component level detail. Any way to get "real" schematics for the CPU board or a new board less than the quoted price of $850.00? Maybe someone knows the chip that usually fails for this problem. I'd pay dearly for the full schematics.

I got a raytheon sl70 pathfinder gps that wont get a fixed signal the antenna is wired right but there dosent seen to be power comeing out of the cord that leads to the antenna. what should i do ????? i...

If you're using a raystar 125 antenna, you will have to power the red wire + and the shield wire - separately. Sl70's don't provide power over seatalk. Also make sure your green and brown wires are properly connected. If it's a 120 just power the red and sheild(black) and leave off the all except the yellow that's your data. If you still have nothing may probably have a problem in the antenna itself.

Connect Ratheon RL 70 to Raymarine E80

The two devices can share Nav data only. No radar, Sonar or Chart will be shared.
Hook the RL70 and the E80 together on SeaTalk and all data will be shared both ways. Alternatively, it could be done with NMEA 0183, which is directional, or you could also translate the RL70 data to NMEA 2000 and share it that way. As long as you have all Raymarine equipment, you are home free using a three wire Seatalk connection, with only two hooked up, Yellow and Bare, color to color.
Remember, this will share Nav Data only.

Raytheon rl70

I've had the same problem. before replacing the antenna, try to reset the antenna by removing power to the Raystar 120. Disconnect power by either turning off all batteries or disconnecting the red wire from the antenna at the point where it enters the junction box for the chartplotter. This action effectively removes all memory from the antenna and resets it to factory settings. There is a lithianium battery in GPS antenna that holds memory data in the antenna. Disconnecting the power to the antenna for a few seconds clears the memory.

This is exactly what I did and when I turned the chartplotter back on, my Raystar 120 immediately began working again.

Replacing an RL-70 with an RL 70-CRC

I did exactly what you wish to do a couple of years ago. It was a 5 minute job, cut out the same except the new unit needs a little more space behind and it was a plug for plug swap. Works great and swaps data between the matching chart plotter to give chart overlay on the radar
