DocumentDocumentUni-COM® CB Modules User Guide UAC-CB-01RS2, UAC-CB-01RS4, UAC-CB-01CAN This guide provides basic installation information for Unitronics' Uni-COMTM CB Modules. Use them to add communication ports to specific models of the UniStream® family of Programmable Logic Controllers. Compatible models comprise a Uni-COMTM CB COM Module Jack which provides the connection point for the module. Refer to the specifications of your UniStream model to check whether it is compatible with CB modules. UAC-CB-01RS2 offers one RS232 port, UAC-CB-01RS4 offers one RS485 port, and UAC-CB-01CAN offers one CANbus port. User Guides are available in Unitronics Technical Library at www.unitronicsplc.com.

Refer to the device's technical specifications Use these to set RS485/CANbus network termination Installation NOTE Turn off system power before connecting or disconnecting any module or device. Use proper precautions to prevent Electro-Static Discharge (ESD). The module is shipped with its COM module jack covered. To protect the jack from debris, damage, and ESD, you must leave it covered when not in use. The final module in a row must have its jack covered. UAC-CB modules can only be installed onto compatible devices, such as UniStream PLCs, or connected to other UAC-CB modules. Installing UAC-CB Modules NOTE Mount on a standard DIN-rail next to a compatible device. Ensure there is sufficient space to install/uninstall modules. In the first figure below, the module being installed is UAC-CB-01CAN; the second figure shows a UAC-CB-01RS2 being connected to the UAC-CB-01CAN. Installing the first module onto the side of the controller: 1. Check the controller to verify that its COM module jack is not covered. If the Uni-COMTM CB module the last one in the configuration, leave the COM jack covered. 2. Push the module onto the DIN-rail until the clips located at the top and bottom of the unit have snapped onto the DIN-rail. 3. Slide the module as shown in the accompanying figure, until the COM module plug is firmly seat in the other devices' COM module jack. Connecting additional modules onto the first: 1. Check the module that is already installed to verify that its COM jack is not covered. If the UAC-CB module is to be the last one in the configuration, do not remove the cover of its COM jack. 2. Insert the module's connection plug into the jack until it is firmly seated. NOTE 2 If you mount vertically, place a DIN-rail stop or end clamp under the final module in the configuration. This is especially recommended if vibrations are present. Unitronics Removing a Module You must remove the end module in a row before removing the next one. 1. Turn off the system power. 2. Disconnect any wires or cables connected to the module. 3. Press the clips on the top and bottom of the modules, and carefully pull the module from its place. Uni-COMTM CB Wiring Caution All wiring activities should be performed while power is OFF. Unused points should not be connected (unless otherwise specified). Ignoring this directive may damage the device. Double-check all wiring before turning on the power supply. To avoid damaging the wire, use a maximum torque of 0.5 N·m (5 kgf·cm). Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to break. Install at maximum distance from high-voltage cables and power equipment. Wiring Guidelines In order to ensure that the device will operate properly and to avoid electromagnetic interference: Use a metal cabinet. Make sure the cabinet and its doors are properly earthed. Use shielded cables. NOTE For detailed information on avoiding EMI, refer to the document System Wiring Guidelines, located in the Technical Library in the Unitronics' website.

Description Not connected Receive Data Transmit Data Not connected Signal Ground Connected to Pin 7 Connected to Pin 6 Not connected UAC-CB-01RS4 RS485 module Wiring Procedures Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2 3.31 mm2). 1. Strip the wire to a length of 7±0.5mm (0.275±0.020 inches). 2. Unscrew the terminal to its widest position before inserting a wire. 3. Insert the wire completely into the terminal to ensure a proper connection. 4. Tighten enough to keep the wire from pulling free. Use the RS485 port to create a multi-drop network. The UAC-CB-01RS4 is shipped with a 4 pin RS485 terminal block. This connector is marked with a pin assignment that is identical to the corresponding marking on the module.

When wiring each node, connect the cable shield to the functional ground point of the RS485 terminal block. Caution In order to avoid ground-loops, do not connect the RS485 functional ground terminal to the earth of the system, as it is internally connected to the controller's functional ground point. RS485 Termination Use the DIP switches shown in the diagram on page 2 to set the RS485 termination according to this table. The device is shipped with both its DIP switches set to ON; change settings if the device is not at one of the ends of the RS485 network.

Connect one connector to your CANbus network. The other connector may be used to daisy-chain to another device. CANbus Wiring Use CAT-5e shielded cable with RJ45 connector. When wiring each node, connect the cable shield to the shield of the RJ45 connector. Connect the CANbus cable shield to the system earth at only one point near the power supply.
