Ancient Networking for Dummies!

post #1 of 3
Thread Starter 
If anyone could help, I would get on my knees and bow down to your ever amazing greatness.

We have an ancient tooling machine that can be programmed
with an ancient laptop to do the tooling for it. Recently, they no longer communicated with each other. Previous forms of communication were done using a 25pin connector which plugged into the machine and a 9pin which plugged into the PC. We figured the cable broke.

I went on Monoprice and got this: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10212&cs_id=1021205&p_id=480&seq=1&format=2

We plugged it in and still, no connection. Sure, it could certainly be the connector on the laptop or the machine itself, but could it also be the cable I bought and the fact that there are different RS-232 cables?

What model "tooling machine" is it? Bridgeport? Mill, lathe, CNC step grinder? Mor info would be helpful to me. Use to own a SERIES 1 EZ-TRAK Bridgport mill that lost communication with the onboard screen and controls. Turned out to be a comm. card plugged into the main board had a blown cap. Replaced and all was well. Not sure if the same situation allies or not, but I thought it might help. Also RS-232 standards are just what the name implies, it's a standard, so unless the tooling center or the laptop used a non-standard communications interface, the cable should be fine.

My savior has arrived!

It's a Tsugami lathe. It's pretty old but after the cable didn't work, I started to suspect a connector on the laptop (which is one of those super armored ones you find in cop cars, cept it's also very old) or the machine itself. I'm not sure if it could be something plugged in. I'm not the primary user of the machine, though I can ask tomrrow. The reason I asked about RS-232 is because I read about DTE and DCE and the such and wasn't sure if that could have been the issue.

The computer also has some type of 48MB flash memory slot with male pins sticking out from it but I can't for the life of me figure out what would go in there.
