erpreting the connectors as I do not see a cable connected to the serial port in your picture. It is below the JTHW port connector. From your picture, this unit does not have the RS-422 connector.

Thanks for the instruction. I will contact them and seek for help.

I would never connect a serial port to the JTHW. The picture is the current state of that port.

Hi Steve, 

 

Thank you for your response. Sorry that it took me a while to get back. I opened the panel and saw the JTHW Port (Dsub 25 pin connector) is occupied and the other end is into PLC I/O cards. Is that why the PMAC PACK did not give a response back to the computer when using RS232 cable? 

Also, we had 2 modules of PC833. The RS232 serial port on there does not give any talk to the computer either when I plug them in. There is a J3 feedback port - looks like a D sub connector - I think it is for encoder feedback. 

If we ought to make a connection to make changes on the gantry control, do all the connections need to come off ?

Thank you!

Hi, 

I am working on a PMAC pack that is working with other two PMAC PC 833 to control a XY gantry. I wonder if there is any quick way to plug and play into the PMAC pack system to pull its "G-code" program to verify with our backup program. 

I tried to use the RS232 port on all three unit but none of them were seem to be fo und as COM port on a computer. I wonder if the manual said that if RS422 is taken then RS232 would be inoperative. Is there another way?
