    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. - 4 -...
  • Page 5: Wiring Requirements

    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. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum rating, the wiring could overheat, causing serious damage to your equipment.

    IMC’s top panel. Front View Communication Connections IMC-21 has one 10/100BaseT(X) Ethernet port. RJ45 Ethernet Port Connection The 10/100BaseT(X) port located on IMC’s front panel are used to connect to Ethernet-enabled devices.
  • Page 7 RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring Fiber Optical Port Connection The concept behind the SC/ST port and cable is quite straightforward. Suppose you are connecting devices I and II. Contrary to electrical signals, optical signals do not require a circuit in order to transmit data. Consequently, one of the optical lines is used to transmit data from device I to device II, and the other optical line is used transmit data from device II to device I, for full-duplex transmission.

  • Page 10: Dual Speed Functionality And Switching

    Auto-Negotiation and Speed Sensing Moxa IMC-21 series’ RJ45 Ethernet port supports auto-negotiation in 10BaseT and 100BaseT(X) modes, with operation governed by the IEEE 802.3u standard. This means that some nodes could be operating at 10 Mbps, while at the same time, other nodes are operating at 100 Mbps.
