H.3 Polling Address
To participate in the Central Reporting System, each SmartScanIS must have a polling
address. What the address is depends on which mode you're in. In Poll/Standalone mode,
the address is based on a single alpha character designator. In Dialup mode, the address is
based on the site name.
H.4 Messages
All messages sent between the SmartScanIS and the Central Reporting System use a fixed
