Network Connection
The FM‑531HD audio processor has a 100Base‑T Ethernet port on the rear
panel. The port is Auto‑MDIX, allowing it to support straight through and cross‑
over cables. The Ethernet interface can support up to four simultaneous connec‑
tions to remote GUIs.
Networked systems are normally connected to the FM‑531HD via “straight”
(pin to pin) CAT5 cable. For typical CAT5 cable pinouts see below. These con‑
nections are for communicating with the configuration computer via a network.
If you are connecting directly between the computer and the FM‑531HD with
no network in between, it is normal to use a crossover cable.
