CLEANUP Function
"Q" + CRC
This command activates the cleaning function.
It is equivalent to push the two buttons ZERO and
PROBE together on the HeliTest front panel.
This command is available only when the unit is in the
REMOTE operation mode (letter "R" is flashing on the
HeliTest display).
REQUEST OF INFORMATION
Operating Status Request
"A" + CRC
The HeliTest answers with a character (+CRC) with the
following meaning:
7
6
5
4
3
2
1
0
–
bit 0 = zero: 0 =AZ; 1 = FZ
–
bit 1 = probe: 0 = OFF; 1 = ON
–
bit 2 = audio: 0 = OFF; 1 = ON
–
bit 3 = sensitivity: 0 = HS; 1 = LS
–
bit 4 = mode: 0 = MS; 1 = SP
–
bit 5 = local/remote: 0 = loc.; 1 = rem.
–
bit 6 = light: 0 = OFF; 1 = ON
–
bit 7 = always 1.
This information can be requested also when the
HeliTest is set for LOCAL operation.
Operating Phase Request
"B" + CRC
The HeliTest answers with a character (+CRC) (with the
bit 7 always 1) indicating the actual operating phase.
The character has the meaning detailed in the following
table.
