Important Note!

 For high density applications with C8491 or C8492 

status display 

and C8492(B) compact modules, it is possible to operate the 

CAN bus

 

if 1MBit/s is used: 

with 

1MBit/s

 to increase the internal bandwidth for loudness logging 

and metering. After power-up the 

C8702

 checks the 

CAN bus

 and 

automaticlly sets its 

CAN bus

  speed accordingly. If by accident one 

inserts a low speed module afterwards, the C8702 will enter "CAN bus 
off mode" and will reboot after a while until that module is removed. 

 
Don't mix up 

modules which are set to

 different 

CAN bus speeds. 

 
For loudenss logging, live plot or bar graph display you must use the 

J*AM

 from version 2.9.0 and higher.
