15.3.2 Computer data setting from PC to OSP
Computer OSP
Tx IDNAME → Rx IDNAME Proceed if the name is acknowledged
Rx IDNAME ← Tx IDNAME If not, do not answer
Tx Instruction → Rx Instruction
Rx Instruction ← Tx Instruction
Tx DATA 1 → Rx DATA 1
Rx char ← Tx char
Tx DATA 2 → Rx DATA 2
Rx char ← Tx char
Tx DATA 3 → Rx DATA 3
Rx char ← Tx char
Tx DATA 4 → Rx DATA 4
Rx char ← Tx char
Tx CHKSUM → Rx char
Rx char ← Tx char
IDNAME, Instruction, DATA 1, DATA 2, DATA 3, DATA 4 and CHKSUM are 8-bit values (1 byte).
CHKSUM = DATA 1+DATA 2+DATA 3+DATA 4 .AND. FF
The above is useful to verify correct received data.
The minimum time-out of OSP is 3 seconds.
IDNAME is set to 1.
