RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring
RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
NOTE If the PD only supports MDI mode (V+, V+, V-, V- for pins 1, 2, 3,
6), choose a cross-over Ethernet cable to connect the PD and the
EDS switch. If the PD only supports MDI-X mode (V-, V-, V+, V+
for pins 1, 2, 3, 6), choose a straight-through Ethernet cable
between the PD and the EDS-P206-4PoE switch.
100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is 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.
Remember to connect the Tx (transmit) port of device I to the Rx (receive)
port of device II, and the Rx (receive) port of device I to the Tx (transmit)
port of device II. If you make your own cable, we suggest labeling the two
sides of the same line with the same letter (A-to-A and B-to-B, as shown
below, or A1-to-A2 and B1-to-B2).
