Well I just ordered a couple of the following 26 pin connectors to prepare to make a interconnect cable, between the 3001 main frame and my 3001E expansion frame.
Its going to be hit and miss, since I have NO idea of the 3001E Texlink plug pinouts. Just wish I could get data on these TekLink 174-1391-00 or 174-1152-00 cables
What I plan to do is make a short cable to break out measuring points, with the 3rd 26pin connector I bought. Then I plan to plug it into the 3001E and
1. using a multi-meter first, make note of the voltages of each pin.
then
2. using an oscilloscope, I will probe each pin to see if there is any signals.
3. Once I have an idea if pins 15,12,11 on the 3001E, have no signals coming out, then I will feel comfortable to connect them to the same pins from the 3001 connector J910.
4. Then I will do the same measurements on pins 2,4,6,8, 26,20,22, 19 & 17.
Then its a time to think and evaluate what I have measured before I try building a interconnect cable.
