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.
