Switch S3 is an eight position DIP switch used to configure

the 1558D unit address ID for the NET A hardware and the

NET B hardware. Unique addresses must be optioned for

each 1558D unit when multiple units are co-located and a

1559 Site Manager is being used. If no manager is being

used, the user should leave the DIP switches in the factory

default positions (all in the OFF or DOWN position). This

configures the unit for NET A address 1 and NET B address

2. Table 2-H indicates how to configure the address settings

for the first six 1558D units.

When connecting to the SUPV port using the

APS local access software, the 1558D NET A

and NET B addresses are viewed as a single unit

address and are displayed as 1.01 for addresses

1 and 2, 1.02 for addresses 3 and 4, etc.
