Ethernet RJ45 Connections
Each RJ45 port is adaptive and supports auto MDI/MDI-X connection. They can be
connected by straight through or cross-over cables to terminal devices, servers, hubs or
other switches. Each switch supports IEEE802.3x so the optimum transmission mode
(either half-duplex or full-duplex) and data rate (either 10Mbps or 100Mbps) will be
selected automatically. The connected devices should support this feature too however, if
the connected devices are not adaptive, the port will send at the correct rate but with a
default mode of half duplex.
2.5
Fiber Optic Connections
The ESUL4-FL1 offers one full duplex fiber port of 100Base-FX which can be single-mode
or multi-mode. The optical connector is a duplex SC. The interface should be used in a
pair (Tx and Rx), where the Tx interface is the optical transmitting terminal which
connects to the optical receiving terminal (Rx) of the remote device. The optical Rx is the
receiving terminal which connects to the transmitting terminal (Tx) of the same optical
interface of the remote device.
2.6
Power Connections
A 5 pin, 5.08mm power terminal block should be used to connect the power cable to
the unit.
