FCC WARNING

Class A for Ethernet Serial Server (Model GW312/315 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 NETEON Technologies could void your

authority to operate the equipment.

1 Introduction

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. NETEON Technologies has

overcome the limit with a family of GW312/315 Series Ethernet Serial Servers. The GW312/315 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 GW312 is for RS 232/RS 422/RS 485 without isolation protection built-in, while the

GW315 is for RS 422 and RS 485 devices built-in isolation protection.

1.1. Packaging

Neteon GW312 /GW315 Ethernet Serial Device Server x 1

5 pins Terminal Block for Serial Connector x 1 (Only for GW315)

3 pins Terminal Block for Power Connector x 1 (Only for GW315)

Wall-mounting screws x 2

Neteon Serial Server quick start guide x 1

Product CD containing configuration utility x 1

Power Adapter - DC Jack 12VDC,1.25A with Lock (Only for GW312)

Optional Accessories：

- Din Rail Kit DK-25

1.2. Modes of Operation

The GW312/315 Series can be operated in one of the following 4 modes:

TCP Server Mode：GW312/315 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 (Fig.1 TCP Server Mode).

User manual Version 1.4

TCP Client Mode：GW312/315 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 (Fig 2 TCP Client Mode).

Fig. 2. TCP Client Mode

UDP Mode：UDP is a fast but non-guaranteed datagram delivery protocol. GW312/315 can be

configured in a UDP mode on a TCP/IP Network to establish a connection, using

unicast or broadcast data to and from a serial device to one or multiple host

computers (Fig 3 UDP Mode).

Fig. 3. UDP Mode

Tunneling Mode(Pair Connection)：The tunneling mode is used for multiple serial devices to “talk” to each

other through GW312/315’s and their Ethernet connections (Fig 4 Tunneling Mode). This mode is particularly

useful when two serial devices are far away, because their communication distance is limited to 15 m.

1.3. Hardware Description

NOTE:

1. Model GW312 is for RS-232/422/485 without isolation protection built-in; GW315 is for RS422/485 with

isolation protection built-in. See Appendix A.3.1 for full Panel layout.
