BUILDING CABLES

---

Tower cables:
Cut off two lengths of 8 conductor wire. One about 38" long for the Tower harness and one about 32" for the Sensor harness. Cat5 wire works great for this. One cable will have a male DB9-2 sub connector attached (for the sensors) and the other cable will have a female DB9-1 connector attached (for the tower). Photo here. The colors showing on this diagram do not represent any coding, but just shows which pins are used. Another diagram to use when building your DB9 cables is here. Use caution when soldering Cat5 wire as to not to apply so much heat that the insulation melts. Notice that I added a nut on the backside of the DB9 connector which isn't provided with the connector. Be careful to check all wire connections (remember at times you will be looking at the diagram in reverse). And again, remember to check the gender of the connector before soldering.

Start Switch:
Cut about 35 feet (depending on the length of your track) of two conductor wire (speaker or phone wire). On one end attach the Roller Switch. Notice that you have a common, normally open and a normally closed terminal. Solder one wire to the common terminal. Depending upon your particular setup at the gate, connect and solder the other wire to the NO or NC terminal. Important: The MicroController expects a high (5 volts) when the gate is in the idle position. You can always change this again later. Polarity or wire color is of no consequence. On the other end of the wire attach and solder the Phone Plug (banana jack). Again polarity doesn't matter. Note: if using phone wire, use little heat because the insulation melts easily.
