Chapter 1: Hookup Instructions - RS232 Interface

SIO JACK VERSION

Attach a standard Atari SIO cable to the Atari Computer or to the last device in your SIO chain.

Attach the other end of the SIO cable to the SIO jack on the SIO2PC/ProSystem Interface.

Attach one end of a standard DB9 serial extension cable to the DB9 connector on the SIO2PC/ProSystem Interface and the other end to a serial port on your PC.

If you use a serial extension cable be sure it is a 9-pin Male <-> Female cable wired straight-thru. Do not use a cable designed for use with a modem or any gender changers or port adapters. Use of improper cabling can damage your interface. Interfaces damaged in this way are not covered by the product guarantee and will be subject to a $10 US repair fee for chip replacement.

If you don't have a serial extension cable, it is possible to plug the interface directly into the serial port of the PC by removing the two female bolts on the DB9 serial connector, though this method is not recommended.

Turn on the Atari computer briefly to test your connections. The POWER LED should glow while the Atari computer is turned on, while the RX and TX lights will flicker briefly as the computer attempts to boot.

If the power LED does not light re-check your connections and try again.

You should now be ready to use APE or SIO2PC software. If you are using APE, start the Cable Configuration Wizard to automatically recognize your new interface.


TERMINAL BLOCKS 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.

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.

The SIO connector pinout, should you need it for debugging is shown below.
