Take the following steps to wire the digital inputs:
STEP 1
: Insert the negative (ground)/positive DI wires into the
┴
/I1
terminals.
STEP 2
: To keep the DI 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 the EDS-505A/508A’s top panel.
Communication Connections
EDS-508A models have 8 or 6 10/100BaseT(X) Ethernet ports, and 0 (zero) or
2 100BaseFX (SC/ST-type connector) fiber ports. EDS-505A models have 5 or
3 10/100BaseT(X) Ethernet ports, and 0 (zero) or 2 100 BaseFX (SC/ST-type
connector) fiber ports
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on EDS’s front panel are used to connect to
Ethernet-enabled devices.
Next, we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.
