Replacing an RL-70 with an RL 70-CRC

Just like every radar detector made since early 90's - X, K, Ka radar bands and laser. Now there are laser pulses of the newer laser guns that the 1610 wasn't designed for so it won't pick them up but on the radar side its current.

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.

depending on the type of boat you currently have it mounted on, you may be out of range. Also your radar may need tuning and make sure your rain and seaclutter is not too high. Make sure the rain clutter is off. If the radar is mounted on a sailboat and you're having this problem, it's most likely the height unless it worked before in which case it could either be the display or the radar components. Magnetrons which run the radar also have a life.

yes? what about it? it is difficult to guess what you wanjt from this description with no other leads.

Generic problem for all JRC GPS Devices Wire connection from chartplotter to radar dome

If both plotter works but they have no comunikation
RESET the RL 70 AND L760
This is how it works
press the powerbutton when you have picture press the menu bottom
than systemsetup and than four seconds the menu bottom.
Do this on both plotter normaly after this it works again

its just warning you that the hub is sapping too much power from the imac, newer hubs are only a couple of $$ and are much more power efficient, try somewhere like dealextreme.com

Your belt on the inside of the dome has come off. Take a small allen wrench with you when you go to check on it.

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.

I have one of these same units brand new for sale real cheap
