STEP 1: Insert the negative/positive DC wires
into the V-/V+ terminals.
STEP 2: To keep the DC wires from pulling loose,
use a small flat-blade screwdriver to tighten the
wire-clamp screws on the front of the terminal
block connector.
STEP 3: Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on IMC’s top panel.
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.
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.
