Partyline: Which CAT-5 cable pairs should I use when wiring a FIM-202D to a remote IF4W4?
After configuring a port as DIRECT in ECS, you would take that port to the MATRIX side of the local FIM-202D. At the remote end, when connecting the remote FIM-202D via the PANEL RJ45, you'd use pins 4 & 5 on the CAT-5 cable (The blue pair) to the IF4W4's receive side and pins 3 & 6 (the green pair) to the IF4W4's transmit side.
