Configuration Parameters

The DIP switches allow you to configure the following items:

• Starting Logical Rack Number (Logical Rack) – is the 1747-ASB module’s

starting logical rack number in the scanner’s image.

• Starting Logical Group Number (Logical Group) – is the 1747-ASB

module’s starting logical group number within the scanner’s image.

• Baud Rate (Baud Rate) – is the 1747-ASB module’s RIO link communication

rate. The baud rate must be the same for all adapters on the RIO link.

• Primary/Complementary SLC Chassis (PRI/COMP) – determines

whether the 1747-ASB module appears to the scanner as a primary or

complementary chassis.

• Adapter Image Size (IMAGE SIZE) – indicates the I/O image size to be

reserved for the adapter. It can be any size between 2 and 32 groups in

2 logical group increments.

• Hold Last State (HLS) – determines whether the discrete output modules

are held in their last state when:

– RIO link communication with the 1747-ASB module is lost.

– The scanner inhibits the 1747-ASB module.

– The scanner sends Reset, Adapter Decide commands to the 1747-ASB module.

• Processor Restart Lockout (PRL) – determines whether the 1747-ASB

module automatically resumes RIO link communications if communication is

lost and then restored.
