acceptable range is the Backup position and Primary converter positions one and two.
For the NSUN changes to any of the thirteen positions are accepted.

Response: $ACS
ACS: Active chain position Status indicator
ssssssssssss: 13 positions of ASCII characters, the first character represents the
backup position followed by primary position 1, the last character
represents primary position 12.
0 = NSU-Converter Serial Link enabled
2 = NSU-Converter Serial Link disabled
* = no change to stored value in position
ccccccccccccc: 13 positions of ASCII characters, the first character represents
the backup position followed by primary position 1, the last character

- = deactivate redundancy chain position
* = no change to stored value in position
The QUERY command requires no parameters. The query form of this command
informs the operator of the operational condition of each NSU-Converter Serial Link and
the status of the converter contacts in the redundancy chain.

0 = No Fault – chain position active
1 = Fault –chain postion active (Fault reported normally)
2 = Fault - chain postion active both contacts open
3 = Fault - chain postion active both contacts closed
- = chain postion inactive disconnected from redundancy chain
+ = chain postion inactive connected to redundancy chain
