d. Scanning command on request (Data sending on request ) -
0x46 (‘F’ ASCII)
When DS2 is programmed in Remote Mode
– Data Sending On Request, the host sends this
special command to request the information packet relative to each single beam or partial scanning
information in the form of one or two numeric measurements of the following type:
- Top Beam (dark or light)
- Bottom Beam (dark or light)
- Middle Beam (dark or light)
- Total Beam (dark or light)
- Total Contiguous Beam (dark or light)
- Transition number (dark or light)
Host sends:
0x1B
0x46
DS2 replies:
The DS2 replies with one of the following packets according to the selected programming mode:
- Complete Binary Scanning (Beam Status Array) -
0x41 (‘A’ ASCII)
- Complete ASCII Scanning (Beam Status Array) -
0x41 (‘A’ ASCII)
- Partial Binary Scanning (Measurements) -
0x42 (‘B’ ASCII)
- Partial ASCII Scanning (Measurements) -
0x42 (‘B’ ASCII)
For the description of these packets, see section
“Scanning modes”.
e. Remote configuration reading command -
0x47 (‘G’ ASCII)
Reads the binary information relative to the remote configuration.
Host sends:
0x02
0x01
0x47
0x03
0xB7

0x08
0x67
rrrrrrr
0x03
x
where:
rrrrrrr = 7 bytes with the remote configuration status (see
Synchronism
packet)
x = checksum (complement to one of the
Length
,
Type
and
Data
field bytes sum)
f Remote configuration writing -
0x48 (‘H’ ASCII)
Saves in the DS2 non-volatile memory the binary information of the remote configuration.
Host sends:
0x02
0x08
0x48
