Advantech EKI-1352, EKI-1351 manual Wireless Connection, Power Connection

2.3.2Wireless Connection

EKI-1351 and EKI-1352 operate in the 802.11b/g WLAN environment, which is created by an access point working with 802.11b/g protocols. Locate your access point and connect to the Ethernet network first. Then build up the connection between the access point and the EKI-1351 and EKI-1352. While the host PC can not connect to EKI-1351 and EKI-1352, you might switch the EKI-1351/1352 as Diag. (Diagnostic) mode.

„Set the switch of EKI-1351/1352 to Normal mode, then power on.

„Wait for 10 to 20 seconds until the signal quality is stable.

„Adjust the switch to Diag. mode, and then wait for about 5 seconds until the signal strength LED is blinking.

„Return the switch to Normal mode, EKI-1351/1352 will reboot automatically with diagnostic infrastructure mode. Now EKI-1351/1352 will search the filed site for access points and create the connection to the one with best signal strength.

„Start the configuration utility tool on your host PC (ensure your host PC and the possible access point the EKI-1351/1352 can connect to, are in the same net- work domain). Find the EKI-1351 or EKI-1352 on the network.

„Reset the network setting as required. (About network settings, please refer to next chapter of the manual)

After the connection is ready, you can follow the steps shown in chapter 3 to config- ure and virtual COM port mapping through network and access point.

You can check the signal access strength with the WLAN signal strength LED indicators. Adjust the antenna of the EKI serial device server to optimize communication quality.

2.3.3Power Connection

The EKI-1351/1352 supports dual 12 to 48 VDC power inputs and power-fail relay output.

Figure 2.14 Power Connector

You can connect an alarm indicator, buzzer or other signaling equipment through the relay output. The relay opens if power input 1 or 2 fails (“Open” means if you connect relay output with an LED, the light would be off).
