Setup
Keyboard Lock Status
This selection lets you lock the front panel operator function key,
Change SP, so that pressing this key has no effect. If you want to use
this function, turn off the Keyboard Lock.
Selectable values: On or Off
Scanner Address
This menu allows you to set the CAS scanner address. The scanner
address is used for multiple scanner communications on a single RS-485
cable, so each CAS must have a different address. Begin with address 1
for the first scanner and assign each subsequent scanner the next higher
address.
Selectable values: 1 - 32
Communications Error Checking
This selection allows you to set the data check algorithm used in the
Anafaze communications protocol to Block Check Character (BCC) or
to Cyclic Redundancy Check (CRC). CRC is a more secure error
checking algorithm than BCC, but it requires more calculation time and
slows the CAS communications. BCC ensures a high degree of
communications integrity, so we recommend that you use BCC unless
your application specifically requires CRC. Also, if using Anascan,
ensure that the same error checking algorithm has been set through the
’scaninst’ program.
Selectable values: BCC or CRC
