TERMINAL BLOCKS VERSION
SIO2PC Universal - USB/Terminals Version
Hookup of this interface requires a SIO cable with one end removed and the wires exposed.
Each wire that is to be inserted into the SIO2PC interface should have approximately one half inch of bare copper showing. Do not insert the wires into the interface without stripping them or they will not make contact, even when the terminals are tightened.
To attach the wire to the terminal block, use a small flat head screwdriver and turn the appropriate terminal block screw counter-clockwise until the corresponding clamp on the front of the interface opens completely.
Insert the stripped end of the wire into the terminal block space and while holding the wire in place, turn the screw on the terminal block clockwise until it is very tight, capturing the wire inside the terminal block.
Repeat this step for each wire according to the color chart below.
Many SIO cables have different wire color schemes, a few of the most common ones are listed below.
Unused wires should be cut short with no copper exposed to prevent shorts.
