d. Scanning command on request (Data sending on request ) - 0x46 (ASCII ‘F’ )
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
DS2 replies:
0x02 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)
