15.3.2Computer 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.
