Installing dual Networkers on a system
Follow these procedures when configuring the two Networkers. The two Networkers
must be configured as master or slave. The Networkers should never be configured
as both masters or both slaves as the system will malfunction. Because all
Networkers come set as masters by default, only the Slave needs to be addressed.
Method 1 can only be used if both Networkers are masters. Refer to method 2 if the
Master and Slave Networkers are to be reversed, or if both Networkers have been set
to Slave by mistake.
Method 1 (new installation).
•
Connect both Networkers to the appliance and power the system up. At this stage
both Networkers will be set as Masters, so both Networkers should have the word
"clock" next to

in this state as there will be communication errors.

Determine which Networker you wish to be the Slave.
