EKI-1121L/1122L/1124L User Manual 6
In this chapter, you will be given an overview of the EKI-1121L/1122L/1124L hard-
ware installation procedures. As mentioned in the previous chapter, the EKI-1221L/
1222L/1224L comes ready with all network connections, including Ethernet and RS-
232/422 /485 port connections.
2.1 Understanding the EKI-1121L/1122L/1124L
Networks have become increasingly vital for industrial automation applications. Many
control devices today do not have a network port and can only communicate with a
dedicated local PC or control panel. Advantech's revolutionary network-enabling
technology is now allowing control devices with serial ports to connect to the Ethernet
and share networks quickly and cost-effectively. The EKI-1121L/1122L/1124L are
network-based, Modbus gateways for integrating new and existing Modbus/RTU and
Modbus/ASCII serial devices to newer TCP/IP networked-based devices. Manufac-
turers, system integrators, and end users can now take advantage of Modbus gate-
ways to create networked applications for remote managing and accessing data for
their control devices that wasn't possible before.
2.2 Hardware
The following instructions will give the overview of EKI-1121L/1122L/1124L hardware
and its installation.
2.2.1 LED Indicators
There are LEDs indicating the two sets of power status, system status, dual networks
status and serial communication status on the front panel of EKI-1121L, EKI-1122L,
and EKI-1124L. Each of them has its own specific meaning, please refer to the below
table.
