2.3.7 Termination Resistor (JP6)

The onboard termination resistor (120 ohm) for COM3/COM4 can be used for long distance transmission or device matching (Default Open).

		RS-422	RS-485
COM3	Close A	TX3-TR	Data+, Data-
	Close B	RX3-TR
COM4	Close C	TX4-TR	Data+, Data-
	Close D	TX4-TR

Close: Enable termination resistor.

Note: Please refer to Figure A.3 for location of JP6

2.4 LAN: Ethernet Connector

The UNO-3074 is equipped with a Realtek RTL8139C Ethernet LAN con- troller that is fully compliant with IEEE 802.3u 10/100Base-T CSMA/CD standards. The Ethernet port provides a standard RJ-45 jack on board, and LED indicators on the front side to show its Link (Green LED) and Active (Yellow LED) status.

2.5 Onboard Isolated Digital Input

The UNO-3074 has 4 isolated DI channels designated DI0~DI3.

2.5.1 Pin Assignments

The connector type of UNO-3074 is plug-in screw terminal block that enables you to connect to field I/O devices directly without additional accessories. Figure 2.4 and Table 2.4 shows its pin assignment as well as signal description.
