y
4
kk',
where:
y
1
is the input selected for output 1, the range is [1~8]
y
2
is the input selected for output 2, the range is [1~8]
y
3
is the input selected for output 3, the range is [1~8]
y
4
is the input selected for output 4, the range is [1~8]
kk is the unit address (2 digits), the range is [01~16]
Example:
To query the status of unit at address 01, issue the following RS-232 sequence:
'01ww' or '01WW'
To query the status of unit at address 16, issue the following RS-232 sequence:
'CCww' or 'CCWW'
