About the IO/COM Bus Connectors 

The IO/COM Bus connectors provide the physical and electrical connection points between 

modules. The right side connector is shipped covered by a protective cover, protecting the 

connector from debris, damage, and ESD. 
The IO/COM Bus - Left (#3 in diagram) can only be connected directly to a CPU. 
The IO/COM Bus - Right (#5 in diagram) can be connected to an I/O module, or to the 
Base Unit of the Local Expansion Adapter. 

Notes 

 

UAC-01EC2 module must be next to and directly connected to a CPU 

 

In case that the UAC-01EC2 is the only module in the configuration, to which 
nothing is connected to its right: do not remove its Bus Connector Cover. 

 

Uni-COM™ modules cannot be connected via a Local Expansion Adapter. 

 

Installation 

 

 

 

 

Turn off system power before connecting or disconnecting any module or device. 

 

Use proper precautions to prevent Electro-Static Discharge (ESD). 

 

Installing the UAC-01EC2 Module 

 

 

1.  Check the unit to which you will connect the UAC-01EC2 module. Verify that its Bus 

Connector is not covered.  

If the UAC-01EC2 module is the last one in the configuration, do not remove the cover 

of its IO/COM Bus-Right connector. 

2.  Open the door of the UAC-01EC2 

module and hold it as shown in the 

accompanying figure.  

3.  Use the upper and lower guide-

tunnels (tongue & groove) to slide 

the UAC-01EC2 module into place. 

4.  Verify that the clips located at the 

top and bottom of the UAC-01EC2 

module have snapped onto the DIN-

rail. 

 

 

 

  

5.  Slide the Bus Connector Lock all the way to 

the left as shown in the accompanying figure. 

6.  If there is already a module located to its 

right, complete the connection by sliding the 

Bus Connector lock of the adjacent unit to the 

left. 

7.  If the module is the last in the configuration, 

leave the IO/COM Bus Connector covered.
