To remove Moxa IMC-21 from the DIN-Rail, insert a flat-blade screw driver horizontally into the DIN-Rail kit under the IMC-21, and then pull it upwards and release IMC towards you away from the DIN-Rail. Wiring Requirements ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring your Moxa Industrial Media Converter. Calculate the maximum possible current in each power wire and common wire.
Grounding Moxa Industrial Media Converter Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the right most connector of the 3-contact terminal block to the grounding surface prior to connecting devices. ATTENTION This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
Communication Connections IMC-21 has one 10/100BaseT(X) or 10BaseT Ethernet port. RJ45 Ethernet Port Connection The 10/100BaseT(X) or 10BaseT port located on IMC’s front panel are used to connect to Ethernet-enabled devices. Below we show pinouts for both MDI (NIC-type) and MDI-X (HUB/Switch-type) ports, and also show cable wiring diagrams for straight-through and cross-over Ethernet cables.
