10/30 Wiring the programming cable for the VP-100

The programming cable for the Vertical Power VP-100 comes in kit form. Basically, a coiled cable with two telephone jack ends. One of the ends has to be adapted to a 9 pin d sub serial connector.














Here a picture of the tools I used to rewire the cable.
Not shown is also a DVM that is used to check the continuity of the connection.














The first step is to cut off the head of one of the telephone jacks.
Its critical that you don't cut off the wrong connector as the wires are reversed on it.
VP supplied a color photo of the jack so you can identify which one to cut.
Yellow wire has to be on left with clip on top as shown in the photo.



















Trim back the black insulation about 2 inches.
You should have 4 wires: yellow, green red and black.
If you look close at the photo below, you will only see 3.
That's because the black wire had stuck to the black insulation and I cut it off when I removed the insulation. So I have to cut off the rest of the wires and strip back another 2 inches of insulation.
The green wire isn't used so it is cut off.














About 1/8 inch of insulation is removed from the three remaining wires to expose the copper wires.














The exposed wire is pushed into the D sub pins that Vertical Power supplied and crimped with a D sub crimper. I got mine at Fry's Electronics for $26.95.














The three crimped pins are inserted into a 9 pin D sub connector into pins 2, 3 and 5 which I believe is a standard serial arrangement for TX, RX and Ground.














The cover is attached around the connector. Hopefully screwed together instead of screwed up.

10/22 Relocating Wiring

Today we started relocating the wiring and equipment in front of the panel.
We need to make room somewhere to put the Control Unit (Red box in the picture below). The Control Unit is the heart of the Vertical Power system. All of our electrical power will connect to this box.















We removed the vacuum pump filter, regulator and hoses from the instrument bay.
The vacuum pump was removed from the engine. When the vacuum pump is removed, it either needs a cover plate installed on the accessory panel to take its place or a SD-8 gear driven aux alternator can be installed. The SD-8 is an eight amp aux alternator that is engaged if the main alternator ever fails. See http://www.bandc.biz/SD8desc.html.
The Lycoming part number for the vacuum pump cover is 60430. ECI sells them for around $26 and their part number is AEL60430. The spacers for the cover are part number 68593.

We relocated some of the electrical components to make room in the bay.
The below pictures shows the VP Control Unit temporarily mounted in the bay.
The final location may change a little. We are planning on moving the radio and transponder up from the subpanel into the main panel after the Dynon engine monitor is installed and we remove all of the analog engine instruments.
