 Media module M1-8TP-RJ45
The M1-8TP-RJ45 media module has 8 x 10/100 Mbit ports for connect-
ing terminal devices or network segments according to the standards
IEEE 802.3 100BASE-TX / IEEE 802.3 10 BASE-T.
These ports support autonegotiation and autopolarity. The ports are RJ45
sockets. The housings of the RJ45 sockets are electrically connected to
the front plate of the device. The pin assignment is identical to MDI-X.
When the autonegotiation function is enabled, these ports also support
autocrossing.

 Media module M1-8MM-SC
The M1-8MM-SC media module has 8 FX ports for connecting terminal
devices or network segments in compliance with the IEEE 802.3u
100BASE-FX Multimode standard. The optical ports are configured in 100
Mbit/s Fullduplex (FDX) and support FEFI. They have a SC design.
