I have a IB8XOBV4 GaurdLogix controller that intermittently keeps giving me a connection timeout error. I have adjusted the controllers network delay multiplier and moved the output timeout multiplier to 4 ...I verified that my trunk line has terminating resistors on each end there are 2 DNET extenders on the network.. I am using the thick d-net cable. Do any of you have any ideas that I can do to keep from getting this connection loss fault. Yes I have read the manuals.
