Need Help!- V2XT Probe Installation

[racer6645]

Hi all. I would like to attach a probe to my Early V2XT. I believe the software is there because If I turn the probe on A message states that the probe is in contact with something. I am assuming that there is a place to connect the wires to, but I have not found it yet, Can any one tell me where I can get the wiring information from? The only info. I have came from the Yahoo group and I have not found anything there about a Probe yet.

The Other Question is about the cable connecting the A and B communication ports together, what is it there for? I would like to use one of the ports to communicate with my PC.

Thanks In advance, Sam

1, the wiring diagram should show the probe interface. There is a round plug on the casting covering the front of the quill where this plug is located if you have it.
2, are you talking about a black self contained plug on your RS232 DB25 connector? That reroutes the terminal signal to be displayed on the CRT. You can remove it for communications.

George,
1, Thanks for the quick reply. That's one of my problems --- I have no diagrams, can you point me to somewhere that I can get them? It has a 386SX processor. The serial # is XT144.

1, I took the cover off of the front of the spindle that covers the Z limit switches, but I see no unused wires, am I looking in the correct place? If this machine is not wired for a probe, Is it possible to install the needed conductors and make the system work?

2, There are 2 black connectors, one on each com. port, (A and B) with a cable connecting them together. There are 4 or 5 pins on each port connected together by the cable.

Thanks, Sam

Stopped by my office (rare) and looked at maintenance manual 11042556 for the V2XT.
There is no probe interface shown on the schematic for the machine with a BMDC.
however, the machine with the BMDC a probe interface is shown as connector P3.

Cannot identify your Port a and B jumper.
Port A shows a transmit and receive (pins 14,15,16) going directly into the FMDC at K5, and the usual RS232 pin out going to the mother board. Could port B be a parallel printer port?
