How to configure Xenta 913 to talk to C-Bus devices

Environment

• Xenta 913
• C-Bus

Cause

C-Bus is a public protocol which is commonly used in lighting control. Xenta 913 can be configured to talk to C-Bus devices with proper settings.

Resolution

A. Device Preparation

1. C-bus 5500PC (PC Interface) RS-232 port
   
       
    
2. Xenta 913 RS-232A port
   
   
   
   NOTE: Communication is between Xenta913’s RS-232A port (NOT RS-485A port) and 5500PC’s RS-232 port (NOT C-Bus port).
    
3. Communication Cable
   

   Xenta913		C-Bus 5500PC, PC Interface
   RS-232A	<--------------------->	RS-232
   3(TX)	<--------------------->	5(RX)
   4(RX)	<--------------------->	6(TX)
   5(COM)	<--------------------->	4(COM)

   
   Above number are RJ45 jack (as shown below) pin numbers.
   
   

B. Configuration

1. Configure C-Bus device with CBusToolkit. Make sure to write down the Application number and the device’s Group number which Xenta 913 needs to communicate with.
    
2. Configure Xenta 913 in Xbuilder.
   1. Set Application number to 38 (38 is the HEX value of 56).
      
      
       
   2. In DeviceEditor
       
   • The Group number (Hex value) needs to be inputted. Such as ‘01’ in the figure below.
   • Same Group number can be inputted in different lines; however the ‘IO’ type should not be the same, such as ‘R’ and ‘W’ in below figure.
   • ON Only and OFF Only types are NOT applicable to read-only values.
     

C. Verification

1. In Xbuilder, drag all C-Bus points onto Value page.
2. Download Xbuilder project into Xenta 913.
3. Login Xenta 913 webpage and check if all point are correct and can be modified.
    

D. Additional Information

Since CBusToolkit communicates with 5500PC by 5500PC’s RS-232 port, and Xenta 913 also communicates with 5500PC by 5500PC’s RS-232 port. Therefore, Only ONE device can be connected to 5500PC’s RS-232 port for CBusToolkit and Xenta 913.
