ATTENTION
Before connecting EDS to the DC power inputs, make sure the DC
power source voltage is stable.
Communication Connections
EDS-316 models have 14, 15, or 16 10/100BaseT(X) Ethernet ports, and
2, 1, or 0 (zero) 100BaseFX (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.
Below 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.

100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is very 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.
