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

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 merchandize
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)

EKI-1526(TI) | 1528(TI) User Manual 2
1.1 Introduction
This manual provides the necessary information to use the EKI-1526(TI) | 1528(TI).
The Advantech EKI-1500 series of serial device servers consist of fast and cost-
effective device servers between serial RS-232/422/485 and Ethernet interfaces.
The two Ethernet ports allow the EKI-1526(TI) | 1528(TI) to establish two separate
Ethernet connections to two Ethernet domains or switches in the same domain.
Through dual Ethernet connections, the EKI-1526(TI) | 1528(TI) greatly improve the
device connectivity reliability, increases system stability, and simplifies redundant
configuration.
By encapsulating serial data and transportation over Ethernet, the EKI-1526(TI) |
1528(TI) allow virtual serial links over Ethernet and IP (TCP/IP, UDP/IP) networks.
After the Advantech Serial Device Server Configuration Utility (including COM port
redirector driver) installation, standard serial operation calls are transparently
redirected to the serial device servers, guaranteeing compatibility with legacy serial
devices and enabling backward compatibility with existing software. The EKI-
1526(TI) | 1528(TI) also support serial tunneling, allowing two native serial devices to
communicate over a network without any hosts and programming. As a result, you
can extend limited distance, point-to-point, direct serial connections within the plant,
throughout the factory, the facility, the office building, or across the global enterprise.
The EKI-1526(TI) | 1528(TI) are industrial-grade network-based serial device servers
for connecting up to 8 or 16 serial RS-232/422/485 devices, such as CNCs, PLCs,
scales and scanners, directly to a TCP/IP network. The EKI-1526(TI) | 1528(TI)
feature two independent Ethernet ports and MAC addresses to provide a redundant
network mechanism to guarantee Ethernet network reliability. The EKI-1526(TI) |
1528(TI) provide a simple and cost-effective way to bring the advantages of remote
management and data accessibility to thousand of devices that can't connect to an
Ethernet network. The EKI-1526(TI) | 1528(TI) offer multiple ways to configure
through the Windows utility, Web Browser, serial or Telnet console, these methods
make it easy manage many EKI-1526(TI) | 1528(TI) or serial devices on your
network.
