Default adding second hds ...wiring

Does the second hds 10's wiring need to be connected to all that the first one is...??(spliced at the same connecting end points.)
or, does it only need power and Ethernet,and drop cable. I can see the need to double up incase of the first unit shitting the bed, then the same info would still be being sent and read from the second unit. But what is correct.;?

Second HDS.

Red wire to power with 10 amp fuse installed. You may have a spot on the boat with fuses already there if not it will be an inline. Ground goes to grounding bus. NMEA get connected to the existing NMEA backbone. This allows you to share data between the units. We already discussed the sonar already and you have the proper cable for that. The yellow wire allows you to connect the units accessories together to turn everything on from one button. You may or may not want this connected.

What wires are you considering splicing? Should just be hooking up ethernet and NMEA2000 between each of them.

That is what he picked up. I think he was speaking of the power and ground wires.

My thinking is , the vhf is connected to the first and original hds10 gen 1 system via 0183 wiring ,so I was thinking maybe all the wires for the new hds 10 gen1 should be added together at the same connecting points as the original unit IN ADDITION to using the new nmea 2000 cables. Seems logical incase of a failure the functions would still be on the network in one or the other units

For the 0183 use a terminal strip. That will keep that looking pretty organized.

The VHF is a 0183 unit receiving GPS coordinates. You can safely hook up multiple receivers, but the HDS is a 0183 unit transmitting coordinates. You can not safely hook together multiple transmitters. Bottom line, don't do it

Andy,

I am not sure what exactly you are trying to do:

A. Are you trying to hook up the VHD DSC to both of the HDS units so in the event of a failure you still have GPS on the VHF?

B. Is there anything else that you are trying to do?

C. You can use a terminal strip to keep all of this organized. As Stiletto mentioned your first HDS unit are transmitting the data to the VHF so you need to connect that.

Do not connect multiple devices outputing data (Talkers) on to the input (Rx) of the unit. The RS422 protocol is not intended for this type of connection, and data will be corrupted if more than one device transmits at the same time. The output however can drive multiple receivers (Listeners). The number of receivers is finite, and depends on the receiving hardware. Typically three devices is possible.

For your unit the transmit wires are yellow and blue and the receive wires are orange and green, the ground is the shield.

Got it Loud and Clear, That is why I asked first. Leave 2nd unit as a power, drop cable , Ethernet hook up only.

Mike at International marine was and is very responsive . He helped me get this set going even though he has much bigger and much more important things going on. Truly simple to deal with and a nice guy besides!! I would suggest if you have a need for materials or the entire set up electronics to engines give him a shot. You will be glad you did. Especially if you are in Palm beach county.
