Setup
Controller Address
Use this menu to set the MLS controller address. The controller address
is used for multiple controller communications on a single RS-485
cable, so each MLS must have a different address. Begin with address 1
for the first controller and assign each subsequent controller the next
higher address.
Selectable Range: a number between 1 and 32.
Communications Error Checking
Use this menu 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 MLS communications.
BCC ensures a high degree of communications integrity, so ANAFAZE
recommends that you use BCC unless your application specifically
requires CRC.
Selectable values: BCC or CRC.
NOTE
If you are using ANASOFT, be sure to configure
ANAINSTL for the same error checking method that
you set in this menu.
