Re: datamarine wiring or manuals

DMI Marine just completed a rebuild of my Mast Head Unit(MHU). After being promised it would be returned in 3 weeks it arrived in 4 weeks causing us to miss our Thanksgiving weekend trip. Once it did arrive, I replaced the unit on top of the mast only to find that it did not register the correct wind speed and the cups spun irregularly. Called Steve at DMI and he suggested i 'simply' return it. Easier said than done since it was back on top of the mast.

After climbing the mast again i removed the unit. Disassembled it my self to find that the shaft that the cups were on had a magnet that was dragging on the wires inside... thank goodness DMI tested it before returning it to me (haha). Also, overcharged me for the return shipment- Charged me $87.50 and it should have been about $39.

Better luck to you if you decide to use DMI Marine for your repair.

datamarine wiring or manuals

I am trying to eek out the last years of my datamarine gauge set up, and recently replaced the knotmeter display with the "newer" CS100 model (speed, avg speed, trip and temp). I also had to upgrade my speed transducer, and found what I believe to be a suitable unit (SX-160 model) on EBAY. However, there are three wires (red, blk and white) and I am not sure which goes to what in the CS100 (looking for grn, spd, temp, log). I tried blk to grn, white or red to temp, and vice versa, with no luck on instrument display. I then tried same with white as the ground.

I was hoping someone knew what color went to what, or better yet, could point me to a wiring diagram or CS100 manual.
