Posted 15 Dec 2005 Ally.Davidson you might be right. I noticed the other day that the blue hose going to the DL-40 did not have termination resistors. So far that seems like the most plausible scenario. Tommorrow I will try adding them. I also looked for an XP specific driver for the PCMK but could not find anything higher than NT. If anyone stumbles across it please post link. Being that I was connecting to other plc-5's with the included plug and play I figured it was ok. I want to thank all of you gurus and wizards for your patience with this lengthy post and for your helping an "up and comer" Share this post Link to post Share on other sites

Posted 16 Dec 2005 Thanks for the driver. I tried adding the termination resistors this morning but it didn't help (oh well, needed to be done anyway). I'll update the PCMK and see if that does the trick. Share this post Link to post Share on other sites
