Mounting Dimensions DIN-Rail Mounting The aluminum DIN-rail attachment plate should be fixed to the back panel of the IMC-21A when you take it out of the box. If you need to reattach the DIN-rail attachment plate to the IMC-21A, make sure the stiff metal spring is situated towards the top. Wiring Requirements ATTENTION Safety First! • • • Be sure to disconnect the power cord before installing and/or wiring your Moxa IMC. Calculate the maximum possible current in each power wire and common wire.
• • • • • Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
Communication Connections RJ45 Ethernet Port Connection The IMC-21A has one 10/100BaseT(X) Ethernet port located on the front panel for connecting to Ethernet-enabled devices.
Fiber Optic 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.
DIP Switch Settings DIP No. 1 2 3 4 5 Function ON OFF (Default setting) Full-duplex Force Fiber Port Duplex Half-duplex “OFF”: Forces Full-duplex on Fiber port. “ON”: Forces Half-duplex on Fiber port. Link Fault Pass Through Disable Enable “OFF”: Enables “Link Fault Pass Through”, the link status on the TX port will inform the FX port of the same device and vice versa. “ON”: Disables “Link Fault Pass Through”, the link status on the TX port will not inform the FX port.
LED Indicators The front panel of the Moxa IMC contains several LED indicators. The function of each LED is described in the table below. LED Color State On PWR AMBER Off 100M (FX) GREEN On Blinking Off On FDX/COL (FX) GREEN Blinking Off 100M (TP) GREEN 10M (TP) GREEN On Blinking Off On Blinking Off Description Power is being supplied to the power input. Power is not being supplied to the power input. FX port’s 100 Mbps link is active. Data is being transmitted at 100 Mbps.
