TM-350/400 Operating Manual
Where the period value is converted from the four byte binary data as shown in the
example above.
To instruct the TM to output sensor #1 and sensor #2 period, the computer would
send the following message:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(6)+Chr$(2)+Chr$(128)+Chr$(1)+
Chr$(118)
The TM will return two, four byte values containing sensors #1&2 period.
Data logging is stopped by sending the following message:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(6)+Chr$(2)+Chr$(0)+Chr$(0)+Chr$(247)
8. Internal command (Code #7)
9. Internal command (Code #8)
10. Internal command (Code #9)
11. Set active film # (Code #10)
This instruction allows the computer to set the active film number. The message
must be in the following format:
Format: Header, Address, Instruction=10, Length=1, 1 byte Film# (1-100),
Checksum.
