Overview, Specifications, Installation Overview, DIP Switch     iii 

 

Modbus is a registered trademark of Gould Inc.

 

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. 
 

 

Power Requirements:       24 V dc nominal (8 – 28 V dc) 
                         1.5 Watt, UL Class 2 power supply, if needed. 
Mounting: 

35 mm DIN rail 

Dimensions:   3.5” H, 2.8” W, 2.9” D (8.9 cm, 7.1 cm, 7.4 cm) 

 

Field Communication Cable Requirements: 

Ethernet: 

Belden 7882A or equiv. UTP CAT 5 with 
RJ45 connectors (untwisted pair or higher) 

Serial: 

Belden 9842, 9829, 89729, 82729 or Apha 
6202C, 6222C, 58902. UL Listed, stranded, 

twisted pairs, over-all foil shield with stranded drain wire 

 

J1, J2 TTL Port Connectors: 

Two built-in TTL ports 

(DB9 pin male) for ATS/PM connectivity 

 

J3 Ethernet Port Connector : 

One built-in 10 Base T (RJ45) 10 Mbps Ethernet port 

 

J4 Serial RS-485 Port: 

One 5-pin terminal block header with a socket block (J4) 
designed to be daisy chained for up to 32 devices. 

Terminal 1 – RX+ 

Terminal 4 – TX- 

Terminal 2 – RX-  

Terminal 5 – Com 

Terminal 3 – TX+ 

 

Ambient Temperature: 

Operating   32 to 140° F (0 to 60° C) 
Storage - 

-40 to 185° F (-40 to 85° C) 

 

Configuration Parameters:  The parameters that are required 

to make an Ethernet connection are: 

IP Address 

169.254.1.1 

Subnet Mask 

255.255.0.0 

Gateway 0.0.0.0 
TCP Port No. 

10001 

The TCP port is used for passing the data to the applications 
and is configurable for user specific requirement. 

Baud Rates 

19200 (default) or 9600 

Flow Control 

No Flow Control (default)  

Interface Mode  TTL/RS485 – 4 wires (default)  
Reply Timeout 

200 milliseconds (default)  

 

Protocol Support: The following protocols are supported:  

Serial Protocol:   

ASCO I, II, and Modbus 

Transport Protocol: 

TCP, UDP 

Application Protocol:    HTTP, Telnet, Modbus/TCP 

AES Encryption

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). 

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.
