ETC Net3 I O Gateway Setup Guide

I/O Gateway Setup Guide

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

• 7 or 8 data bits

• None, Even or Odd for Parity

• 1 or 2 Stop Bits

• None, Xon/Xoff, Hardware are the Flow Control options

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).

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.

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.

Optional Accessories

Power Up Using DC Power

When using an external power supply, the gateway must be connected to a network before being powered.

Rack Mount Kit (4260K1001)

The Net3 Gateway Rack Mount kit is capable of holding up to two Net3 gateways for mounting into a standard 19” rack enclosure. If you only
need to mount one unit, a blanking plate is provided with the kit. This blanking plate can be installed on either side of the rack mount bracket.

Hanging Hardware Kit (4260K1005)

The Net3 Hanging Hardware kit allows pipe mounting of a Net3 Gateway in a variety of orientations. You can vary the way the U-bolt (or
c-clamp) attaches to the bracket and the way the bracket mounts to the gateway. The bracket attaches to any edge on the bottom of your
gateway.

Menu Structure

The Net3 I/O Gateway has a one button interface. Pressing the [Menu] button repeatedly cycles through the menu, displaying
related data. On certain menu items you are prompted to press and hold the [Menu] button for a period of 5 seconds to
change a state or setting.
