B&B Electronics Zlinx 485 Benutzerhandbuch

 

Zlinx 485 Base modules have three LED indicators: a Power LED, a Data LED   and  a 
Local Bus Data LED.  

Expansion modules have two LED’s: a Power LED and a Local Bus Data LED 

The Power LED illuminates (red) immediately on power up indicating that DC power is 
present on the power supply terminals.  

The  Data LED blinks (green) when data is being transmitted or received, either to an 
expansion module or another base module. When the LED is off no data is being 
transmitted or received. 

The Bus LED blinks (green) when data is being transmitted or received on the local bus 
connection. When the LED is off no data is being transmitted or received. 

Note: If communications is not established within a preset number of retries (default is 10) the Data 
and Bus LED’s blink alternately to indicate a loss of communications. 

Zlinx 485 Base and Expansion modules feature connectors for connecting field I/O 
wiring and plugging together Zlinx 485 modules (local bus). In addition, Zlinx 485 Base 
modules include connectors for connecting a power supply and an RJ45 connecter to 
connect to the PC using the supplied RJ45 to serial cable.
