Help Understanding power to B&G Network Instruments

We recently purchased a New to Us Sailboat and it came with some uninstalled B&G instruments. All 3 are B&G Network Instruments, a speed readout, a wind direction / speed readout and a depth/temp readout.

The manuals list them as being from 1985

On the Depth unit:

A small sticker, the only other marking on the unit for example, says: Net Depth 610-00-0211 and then the serial number of the unit

Across the bottom front are 5 buttons (Depth, Signal, Alarm, Setup anf Lights)

Each unit has a center connection for the appropriate input (transducer, mast head wind speed/direction and speed/temp)

Each unit also has a male and female connector on pigtails (Female on the right rear side (if looking at the face) and Male on the left rear)

My question is, how do I power these?

I understand that the 3 of them can be connected via these "pigtail" connectors to each other to share power and pass along data.

Also, guessing that I supply power into them via one end of this "chain" of pigtails, do I need to terminate the other end? Will it work without termination?

Thanks in advance.... if pics would help I can post them.

Mike

A simple search would have revealed the following

Re: Help Understanding power to B&G Network Instruments

Ahhh I see there is a long list... and I see th einstruments I have listed there, I also HAVE the original manuals, but no where in them does it discuss power... It talks about linking them.... and ssharing of power, but no where how to put power into the system.

I guess to make my question more clear... if power is supplied via the "pigtail" cables, I would need the pinout for them to determine to which pin(s) I would be supplying 12v and ground... and if I need to terminate the opposote ends (eg: if I choose to use only one device do I need to terminate the passthrough?)

Re: Help Understanding power to B&G Network Instruments

Yeh,B&G did a great job of hiding your manuals in the long list....

Browsing through the list, the Network_PLC_Wiring manual has a diagram that may be useful.

I don't know what the pin-outs are on the pig tails, so it might be a bit of a coin toss if you decide to cut one of the plugs off. Hopefully in your pandora's box of goodies you'll find a power connector.

If not then a quick search has revealed some on e-bay, perhaps treat yourself to a Christmas present.

I've emailed B&G to see if they will share the pinout of the power connector.... I'll let the group know the result (and th epinouit incase anyone else ever needs it)

Just buy the proper power connector.

Even if you find the pinouts and cable colors, If you cut the plug off there'll be tears, perhaps not today, but definitely tomorrow.

Re: Help Understanding power to B&G Network Instruments

Why would cutting the connectors off the pigtails produce "tears?" It’s old gear. Finding cables that match the old plugs might be difficult. Plugs are almost always just plugs. Any matching set of plugs will work just fine The B&G Hydra instruments were all supplied with long, unterminated pigtails and connected to the other components using small Eurostrip terminal blocks.

Re: Help Understanding power to B&G Network Instruments

I recommend you sell the instruments as current users are always looking for replacements and spares to keep their old system going.

In my case the proceeds from my old B&G Hydra2000 parts fully covered the price of new B&G Triton displays.
