Overview

The Connectivity Module brings together several different serial devices that communicate at different baud rates and with different protocols to a common Ethernet media. It can communicate with up to eight clients, such as Web applications (web pages), Vpi, or third-party Modbus ® devices simultaneously over Ethernet media.

Installation Overview

1.Determine the kind of network to use to connect the various devices to the Connectivity Module.

2.If a RS485 network will be used, do not install the Connectivity Module until the DIP switches are checked and set on the bottom of the unit. See below.

3.Refer to the outline & mounting drawing (page iv) and wiring diagrams (pages v, vi).

4.Select the appropriate installation (pages 1-1, 1-2) that corresponds to the product to be connected.

5.Establish and test communications (page 1-2). Refer to Status LEDs (page vii).

6.View and change configuration pages (page 1-3).

Check the DIP Switch Settings for RS485

For RS485 networks only, before installing the Connectivity Module check the position of the DIP switch actuators on the bottom of the unit. The upper two actuators turn on a built-in termination resistor, if needed. The lower two actuators select either a 2-wire or 4-wire RS485 network. See the figure below.

Termination Resistor, upper two actuators

On a daisy chained RS485 network the Connectivity Module termination resistor must be ON. Likewise only the farthest device from the Connectivity Module must have the termination resistor ON. All other devices must be OFF. The DIP switch upper two actuators control the built-in termination resistor:

ON – move to left. OFF – move to right.

2-Wire or 4-Wire network, lower two actuators

If a 2-wire RS485 network is to be attached to the Connectivity Module, move the lower two actuators to the left. If a 4-wire RS485 network is used, move these actuators to the right.
