Dear Valued Partners,


We would like to guide you how we can replace the site where 3rd party controller and RFID readers are installed by Wiegand cable with Suprema CS-40 controller, BER2 and/or XPD2. 


 

1. Check Wiegand cable 

 

 1.1 Wiegand cable should be Shielded twisted 2 pair cable. In order to connect RS485+, RS485- and GND to the Wiegand cable, the cable should be 2 pair cable or more. 


1.2 If the cable length is not long enough to connect BER2 or XPD2 with CS-40, you can add cable as below. Note that the cable should be shielded twisted pair cable.


** Sample cable 

  • AWG 24 Belden 9504 Shielded Twisted Pair Cable 
  • AWG 24 Alpha 5472C Shielded Twisted Pair Cable 

 

 

2. Install terminating resistance 

 

2.1 In case that the Wiegand cable characteristic impedance is 120ohm, switch ON terminating resistance of CS-40 and install 120ohm terminating resistance to reader.

 

** Please check cable characteristic impedance with the cable company 



2.2 In case that the Wiegand cable characteristic impedance is not 120ohm, switch OFF terminating resistance of CS-40. It is required to install terminating resistance to both CS-40 and reader. 




3. The max. quantity of BER2 or XPD2 that can connect to CS-40

 

 3.1 

- (1:1) 5ea readers can connect to CS-40

- (1:2) 10ea readers can connect to CS-40 


Ex e-2.


** Please note that terminating resistance must be installed to reader and switch off terminating resistance of CS-40 for daisy chain configuration. 

** Please note that you can not add more than 2 devices with same wiring per a RS485 port of CS-40 to the below picture.


Add case for Power Supply is differente for each reader and SIO2 :


In this case it is mandatory to wire GND from CS-40 to GND from Secure IO but also on XPD2 you will need to wire - to GND also.


Finally all - pole from all Power supply will be connected to GND from CS-40.
