in open status.
IT-ES3020-IU-4GS series support 1 channel relay alarm output, can connect alarm light or alarm buzzer, it can also connect other I/O device,
It is convenience to note operator once alarm.
【DIPswitch】
Top panel provided 4 bits DIP switch to do function configure(OFF is default factory), 1 keep for future function, 2 power alarm open or close, 3
flow control open or close, 4 broadcast storm suppression open or close. Please power off and power on when you change the status of DIP switch.
【Communication connector】
10/100BaseT(X) Ethernet port
The pinout of RJ45 port display as below, connect by UTP or STP. The connect distance is no more than 100m. 100Mbps is used 100Ωof UTP
5, 10Mbps is used 100Ωof UTP 3, 4, 5.
RJ 45 port support automatic MDI/MDI-X operation. Can connect the PC, Server, Converter and HUB .Pin 1,2,3,6 Corresponding connection
in MDI. 1→3, 2→6, 3→1, 6→2 are used as cross wiring in the MDI-X port of Converter and HUB. 10Base-T/100Base-TX are used in
MDI/MDI-X, the define of Pin in the table as below.

MDI-X (Cross over cable)
MDI/MDI-X auto connection makes IT-ES3020-IU-4GS series easy to use for customers without considering the type of network cable.
100Base-FXFiber port
100Base-FX full-duplex SM or MM port, SC/ST type .The fiber port must be used in pair, TX (transmit) port connect remote switch’s RX
(receive) port; RX (receive) port connect remote switch’s TX (transmit) port.
The optical fiber connection supports the line to instruct enhance the reliability of network effectively.
Suppose 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, shown as below,
or A1-to-A2 and B1-to-B2).
1000SFP fiber port (mini-GBIC)
1000BaseSFP fiber port adopts gigabit mini-GBIC transmission, can choice different SFP module according to different transfer distance.
Fiber interface must use for pair, TX port is transmit side, must connect to RX (receive side). The fiber interface support loss line indicator.
Suppose: 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, shown as below,
or A1-to-A2 and B1-to-B2).

【Installation】
Before installation, confirm that the work environment meet the installation require, including the power needs and abundant space. Whether it is
close to the connection equipment and other equipments are prepared or not.
1.Avoid in the sunshine, keep away from the heat fountainhead or the area where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not (less than 100m) according to reasonable scheme.
4. Screw, nut, tool provide by yourself.
5. Power: redundant 12-48VDC power input
6. Environment: working temperature -40～85℃
Relative humidity 5%～95%
DIN rail installation
In order to use in industrial environments expediently, IES618-4D series adopt 35mm DIN-Rail installation, the installation steps as fellows:
1. Examine the DIN-Rail attachment
2. Examine DIN Rail whether be firm and the position be suitability or not.
3. Insert the top of the DIN-Rail into the slot just below the stiff metal spring.
4. The DIN-Rail attachment unit will snap into place as shown below.
Wiring Requirements
Cable laying need to meet the following requirements,
1. It is needed to check whether the type, quantity and specification of cable match the requirement before cable laying;
2. It is needed to check the cable is damaged or not, factory records and quality assurance booklet before cable laying;
3. The required cable specification, quantity, direction and laying position need to match construction requirements, and cable length depends
on actual position;
4. All the cable cannot have break-down and terminal in the middle;
5. Cables should be straight in the hallways and turning;
6. Cable should be straight in the groove, and cannot beyond the groove in case of holding back the inlet and outlet holes. Cables should be
banded and fixed when they are out of the groove;
7. User cable should be separated from the power lines. Cables, power lines and grounding lines cannot be overlapped and mixed when they
are in the same groove road. When cable is too long, it cannot hold down other cable, but structure in the middle of alignment rack;
8. Pigtail cannot be tied and swerved as less as possible. Swerving radius cannot be too small (small swerving causes terrible loss of link). Its
banding should be moderate, not too tight, and should be separated from other cables;

9
9. It should have corresponding simple signal at both sides of the cable for maintaining.
