Product Warranty (5 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for five years from the date of
purchase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is
defective, it will be repaired or replaced at no charge during the warranty period. For
out of-warranty repairs, you will be billed according to the cost of replacement
materials, service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any on screen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandise
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.

Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid
damage, keep static-sensitive devices in the static-protective packaging until the
installation period. The following guidelines are also recommended:
Wear a grounded wrist or ankle strap and use gloves to prevent direct contact to
the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.
Always disconnect the power from the device before servicing it.
Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.

2 EKI-1228-DR Series User Manual
1.1 Overview
The EKI-1228-DR Series Modbus gateways are bi-directional gateways for
integrating new and existing Modbus/RTU and Modbus/ASCII serial devices to newer
TCP/IP networked-based devices. The EKI-1228-DR Series has two independent
Ethernet ports and MAC addresses to provide redundancy and reliability. They
provide a simple and cost-effective way to bring remote management and data
accessibility to thousands of devices that cannot connect to a network. EKI-1228-DR
Series provides a feature that can allow users to select master or slave operation
mode for each serial port. They not only allow an Ethernet master to control serial
slaves but also allow serial masters to control Ethernet slaves.
1.2 Device Features
Provides 2 x 10/100 Mbps Ethernet ports for LAN redundancy
Integration of Modbus TCP and Modbus RTU/ASCII networks
Supports up to 921.6 kbps, and any baud rate setting
Support up to 16 connections on each serial port under Modbus Master mode
and 128 sessions under Modbus Slave mode.
Software selectable RS-232/422/485 communication (RS-422/485 for "CI"
model)
Mounts on DIN-rail and Wall mount
Built-in 15 KV ESD protection for all serial signals
Automatic RS-485 data flow control
Supports surge protection for D.C. power ports with line to line 2 KV, and line to
earth 4 KV; for signal ports with 4 KV
'I' models support a wide operating temperature
'CI' models support isolation and wide operating temperature

2.2 Connecting Hardware
2.2.1 DIN Rail Mounting
The DIN rail mount option is the quickest installation option. Additionally, it optimizes
the use of rail space.
The metal DIN rail kit is secured to the rear of the switch. The device can be mounted
onto a standard 35 mm (1.37”) x 7.5 mm (0.3”) height DIN rail. The devices can be
mounted vertically or horizontally. Refer to the following guidelines for further
information.
2.2.1.1 Installing the DIN-Rail Mounting Kit
1. Position the rear panel of the switch directly in front of the DIN rail, making sure
that the top of the DIN rail clip hooks over the top of the DIN rail, as shown in the
following illustration.
Make sure the DIN rail is inserted behind the spring mechanism.
2. Once the DIN rail is seated correctly in the DIN rail clip, press the front of the
switch to rotate the switch down and into the release tab on the DIN rail clip.
If seated correctly, the bottom of the DIN rail should be fully inserted in the
release tab.
Figure 2.5 Installing the DIN-Rail Mounting Kit
Note! A corrosion-free mounting rail is advisable.
When installing, make sure to allow for enough space to properly install
the cabling.
Warning! Do not install the DIN rail under or in front of the spring mechanism on
the DIN rail clip to prevent damage to the DIN rail clip or the DIN rail.

3. Grasp the bottom of the switch and slightly rotate it upwards. If there is
resistance, the switch is correctly installed. Otherwise, re-attempt the installation
process from the beginning.
2.2.1.2 Removing the DIN-Rail Mounting Kit
1. Ensure that power is removed from the switch, and disconnect all cables and
connectors from the front panel of the switch.
2. Push down on the top of the DIN rail clip release tab with your finger. As the clip
releases, lift the bottom of the switch, as shown in the following illustration.
