The NodeType is a numeric identifier that is stored in EPROM that identifies

the Excel 10 node type. Whenever a new software version or upgrade is

issued, this is reflected in nroPgmVer which typically is read by a network

management node to identify the node type. The contents of nroPgmVer

 

 

 

 

 

 

 

 

 

 

 

 

 

contain compatible model type information and is fixed at the time when the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

node software is compiled.
