can't connect to service port old IRC5 (DSQC 623)

    I have 2 robots, both older IRC5 controllers with the really old solid metal box computers DSQC 623. when I plug an ethernet cable into the service port my laptop shows a connection for a second then no cable connected. I have tried both robotstudio and filezilla to FTP in, but I am convinced there is something keeping my laptop from actually seeing the connection.:question_mark: All my other IRC5 controllers have the newer DSQC 639 or DSQC 1000 computers and those connect without issue.

    Anyone else have one of these older models and are able to connect to the service port? Any help will be appreciated.

    Do the ethernet ports light up? Do the lights match with the connection status Windows reports?

    Kind of an off-the-wall guess, here, but maybe try using an ethernet switch in between the robot and the laptop? The older IRC5s, IIRC, did not have "smart" ethernet ports, and needed crossover ethernet cables instead of straight-through cables. However, this should not be a problem, b/c modern laptops all(?) have "smart" ethernet ports that detect this situation and eliminate the need to use a crossover ethernet cable. I suppose there's a small chance that your laptop's auto-negotiation might be having issues.

    I've also heard of someone who had to reduce the speed of their laptop's ethernet socket in order to get a connection to the IRC.

    Yes I do get both the green and yellow lights on the service port status lights. I'll try to round up an ethernet switch and give that a shot. I'm not sure I am following what you mean by reducing the speed of the ethernet port, could you explain?
