FCC WARNING
Class A for Ethernet Serial Server (Model SE5404 series)
This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses
and radiates radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expenses.
A shielded-type power cord is required in order to meet FCC emission limits and also to prevent interference
to the nearby radio and television reception. It is essential that only the supplied power cord can be used.
Use only shielded cables to connect the device’s ’ RS-232 or RS-485 port.
Be cautioned that changes or modifications not explicitly approved by ATOP Technologies could void your
authority to operate the equipment.

1. I NTRODUCTION
Many industrial and Commercial devices equipped with slow serial communication ports—RS-232, RS-485,
and RS-422—are limited in their transmission distance of 15 m. Examples of these devices are PLC
controllers, card readers, display signs, security controls, CNC controller, etc. ATOP Technologies has
overcome the limit with a family of SE5404 Series Ethernet Serial Servers. The SE5404 sever family is
designed to transmit data between one-or-more serial device and one-or-more TCP/IP device through
Ethernet, and hence enhance the accessibility of the serial device through the ubiquitous TCP/IP based
Ethernet.
Of the SE series, the SE5404 is for RS-232/RS-422/RS-485 without isolation protection built-in, while the
SE5404-S5is is for RS-422 and RS-485 devices built-in isolation protection.
1.1 Packaging
Check your package to make certain it contains the following items:
SE5404◎/SE5404-S5is Ethernet Serial Device Server
Quick Inst◎allation Guide
◎Product Warranty
◎Product CD
◎Rack mounting L type ears*2 (include screw*6)
◎Wall mounting screws*2
◎3-pin terminal block*1 for power input only for SE5404-S5is
◎5-pin terminal block *4 only for SE5404-S5is
◎Optional Accessories：
1. Power Adapter - DC Jack 12VDC,1.25A with Lock only for SE5404
1.2 Modes of Operation
The SE5404 Series can be operated in one of the following 3 modes:
TCP Server Mode：SE5404 can be configured in a TCP server mode on an Ethernet Network to wait
for the host computer to establish a connection with the serial device ( the client).
After the connection is established, data can flow in both directions (Figure 1.1).

Figure 1.1 TCP Server Mode
TCP Client Mode：SE5404 can be configured in a TCP client mode on a TCP/IP Network to actively
establish a connection with an applications server –the host computer. After the
connection is established, data can flow in both directions (Figure 1.2).

UDP Mode：UDP is a fast but non-guaranteed datagram delivery protocol. SE5404 can be configured in
a UDP mode on a TCP/IP Network to establish a connection, using
unicast data to and from a serial device to one or multiple host computers (Figure 1.3).

Step 1:Connect SE5404 to a 12V DC power source Jack. (Or to a 9~30VDC Terminal Block power
source which only for SE5404-S5is)
Step 2: Connect SE5404 to the Ethernet network. Use a standard straight-through Ethernet cable when
connect to a hub/switch, or connect to a PC‘s Ethernet port via a crossover Ethernet cable. However,
Always make sure ones PC is on the same sub-net as the SE5404.
Step 3:Connect SE5404’s serial port to a serial device.
Step 4:Mount SE5404 to a Rack with one pair L type Rack mounting ears included
