Overview

This Setup Guide will guide you through the setup of the Net3 I/O Gateway including hardware, electrical and data

connections. Software configuration of your gateway is covered separately and relates specifically to the software

versions that may be running in the gateways.

• For

Net3 configuration, please refer to the Gateway Configuration Editor (GCE) Online Help System.

• For use on

ETCNet2 systems, use the ETCNet2 Network Configuration Editor (NCE) User Manual which includes

information about the Net3 gateways running in ETCNet2 mode.

RS-232 Serial Port

At the most basic level, the serial port on the I/O Gateway acts as a converter between standard

RS-232 serial strings of information and a Net3/ACN equivalent that is sent over Ethernet. This

allows a control console, or other ACN device, to have a remote serial port and to extend the

normal distance limitations of serial communications. The I/O Gateway does not act on this serial

communication, but acts as a bridge between RS-232 and Ethernet.
The serial property options available are (default settings are in

bold):

•

9600, 14400, 19200, 28800, 38400, 57600 and 115200 Baud

Relay Outputs

When choosing your connections (normally open versus normally closed) to the relay outputs, be sure to consider the default or powered off state

of the relay and how your connected device will react when the I/O Gateway is powered off or reset.
For example, if your device will activate with a closed circuit, don’t choose a normally closed connection and keep it open using a command from a

controlling Ethernet based device. This choice could result in your device activating at an unanticipated time during a software update or when the

gateway is not powered. You should choose the normally open connection instead as it doesn’t activate unless it is specifically directed to do so.

Analog Input Port

The analog input port is used to accept external contact closures and/or analog 0 - 10Vdc input (depending on software configuration) and send

them as Net3/ACN Ethernet messages to a networked control console or other ACN device. This port requires an external 10Vdc power supply to

operate. In On/Off mode (contact closure), the gateway supplies +5Vdc to the circuit through each input pin.

NOTE:

Each relay supports a maximum of 1.0A at 30Vdc.

NOTE:

A straight through cable is required to connect to a computer (use DTE pinout). Connecting to many remote serial

products requires a cross-over cable (use DCE pinout).
