WA-NEX Instruction Manual 

 

What is the WA-NEX? 

 
The WA-NEX is generally used to partition a wired system that has 
exceeded the maximum cable distance of the data run.  Once 
partitioned by a WA-NEX the two partitioned halves will behave 
exactly as if it were a single wired network.  
 
The RAKO wired system has a maximum data network length of 
approximately 3000m.  When using a RAK-STAR the cable length 
is effectively doubled as the data travels out and returns on the 
same cable. This means the maximum is reached with 1500m of 
cable.  
 

Symptoms of excessive cable length: 

The symptom of this maximum data length being exceeded is that newly 
added CAN devices will cause other network devices to disappear from 
the system.  If keypads or other devices that were previously appearing as 
online start going offline as new ones are added and the system is large 
then it is very likely that the total data length has been exceeded.
