Geddy, I purchased the serial cable from UD last week along with the eisy, I dont see a owners manual for the eisy unit and somewhat lost in hookup and operation. On the serial cable I assume I can hook up to any of the usb on the back that is going to the PLM, I do want a hard wired connection as well and have a connection going to my switch, I also have hooked it up as WiFi and I cannot get my eisy to get on my network or internet Ive turned off my virus protection for acess and still nothing. Also as with my old isy I couldnt download the admin console, I have cleared out the cache on Java. I have written a couple of tickets , Im at the point doing the remote support .
