ASR650 Operational Manual

 

 

 
The two ends of the cable  should have a termination  resistor  connected  across the two  wires. 
Without termination resistors, reflections of fast driver edges can cause multiple data edges that 
can cause data corruption. The value of each termination resistor should be equal to the cable 
impedance (typically 120 

Ω for twisted pairs). 

 

 

 

 

The above drawing shows the RS485 schematic of the ASR650 including the fail-safe resistors 
and protection diodes. The resistors are necessary for biasing the lines to known voltages and 
nodes will not interpret the noise from undriven lines as actual data.  
 
The RS485 baud rate can be configured from 9600 to 115200 baud. Please ensure that all nodes 
use the same and correct setting.  
 

 

It is very important that each device on the bus uses a different network- or 
node address. If several readers are using the same address, data collision 
might be the result. You can change the reader’s node addresses via the 

ASR-PC-Demo

 Software. 

 

ASR650 Settings 

In order to allow the ASR650 to work in a wide range of applications, there are lots of possibilities 
for  changing  the  behavior  of  the  reader,  i.e.  for  altering  several  settings.  Therefore,  Agrident 
provides a software which is available for free. You may also control the reader with own software 
or change settings using the corresponding commands according to the ASR650 protocol. Please 
see the ASR650 protocol description for details. 
 
All the different reader settings will be explained in combination with the 

ASR-PC-Demo

 software 

for  stationary  readers  in  the  following  chapters  as  well  as  the  comprehensive  diagnostic 
capabilities.
