USER'S MANUAL. MO-170
6) Once completed the message processing, the MO-170 will send an XON
indicating that its ready for a new command.
A typical communication timing diagram would be as follows:
PC
⇐
1) XON
2)*?NA<cr> ⇒
⇐
3) XOFF
⇐
4) ACK
5) wait ...
⇐
6) *NAMO-170<cr>
7) wait ...
⇐
8) XON
(All characters are transmitted in ASCII code)
Commands should always be sent in capital letter and cannot be edited online,
i.e., once a character is received it is stored in the MO-170 buffer and cannot be
rectified by sending an erase code.
When in communication idle mode (MO-170 waiting for a command) the
instrument will send an XON code at one second intervals, to allow synchronization.
Command list: Commands are classified between interrogative and control
commands. They are initiated by sending an '*' character, and have ASCII text format
and always share a similar structure. For instance, the equipment model name can be
asked by sending "*?NA<cr>" and the answer is "*NAMO-170" (always without quotes)
Some amount of parsing must be applied, to recover the wanted data from the answer
text (in this case, "MO-170")
