What is the name/number of the wire that connects the socket card in the pc to the 9 pin connector that goes to the display board? There is also one that runs from the S-4 timer.Thanks

I assume that you are trying to make a cable from the serial port to the display.

DB9 female connector

pin 3 -signal
pin 5 -ground

a single pair is needed

Display side

Red - Yellow banana plug
Black - Black banana plug

The S4 to display cable does exist in the ALGE cable book.

The Din connector has 5 pins in a square configuration with a center ground pin.

Looking at the connector from the solder side and the notch up

Center pin - ground
7pm pin - signal

A single pair is needed


Display side

Red - Yellow banana plug
Black - Black banana plug

We usually make a "y" cable with 10m of cable and both plugs attached to the wire pair for S4 /display customers. You can only use one signal source at a time anyway.

Dennis,

If you are not trying to make a display cable as Fred mentioned and are trying to find out the #'s and name of your Scocket cards ports go into your Windows device manager (Control Panel / System / Hardware / Device Manager / Ports (COM & LPT) or if you are using Split Second software you can access the device manager from the Setup and Test page where you would assign your Timer and Scoreboad ports.

You will see a list of ports on your computer. The Socket card's ports will be listed depending on if you are using a dual or quad card as follows.

Socket Dual I/O Port A (com?)
Socket Dual I/O Port B (com?)
The question mark will be the com port #

For a quad card it would be

Socket Quad I/O Port A (com?)
Socket Quad I/O Port B (com?)
Socket Quad I/O Port C (com?)
Socket Quad I/O Port D (com?)

This will also show if they are working properly. If you see a small yellow triange with an exclamation point in it then the port is not working properly and you may have to reload you Socket Drivers or software.
