Ethernet port
The E-PDISO16 has one 10/100 BASE-T, auto-negotiation, high-speed communication port. The port
connector is an RJ-45, eight-position connector. The Ethernet port accepts CAT-5 shielded or unshielded
twisted pair cable. The maximum communication distance without using a repeater is 100 meters. You can send
your data 100 meters at data speeds of up to 100 Mbps using only one Ethernet cable connected to your
computer.
External power connectors
The E-PDISO16 has two external power connectors labeled Power IN and Power OUT . Connect the Power IN
connector to the supplied +9 V, external power supply (CB-PWR-9V3A). The Power OUT connector lets you
power additional Measurement Computing products from a single external power supply.
The maximum output current is 3 A. When running at full load, that is, when all relays are on and the Ethernet
is transferring data, the E-PDISO16 draws 1.7 A from the supply. Depending on your load requirements,
additional products may require a separate power supply.
