CI-100 Crucible Indexer Operating Manual
4.3 Command Protocol
The CI-100 communicates with a host computer via an ASCII based protocol. The
instrument RS-232 configuration is set to 19200 baud, 8 data bits, and no parity.
The basic protocol is:
<$> <1 to n data characters> <CRLF>
Once a valid command has been transmitted to the CI-100, a response is returned.
The structure of the packet is identical in both the command and response. In the
response, the character after the $ is a Response Status, as shown in the table:
