CMG-DM24
–GCFIN
Syntax: input-port -GCFIN
Instructs the digitizer to stop accepting GCF input on input-port,
and to return the port to normal operation.
OPEN
Syntax: OPEN system-id stream-id-prefix (n.b.)
Opens a terminal session to a second, connected digitizer.
The DM24 scans all the ports which are currently accepting GCF input
(see +GCFIN, above) to find a digitizer which matches system-id and
stream-id-prefix.
For stream-id-prefix you should use the first 4 characters of the
Stream IDs produced by the required digitizer, i.e. without the
component and tap designations.
A terminal connection is then made to the second digitizer, allowing
you to issue commands.
To finish the session and return to the first digitizer's terminal mode,
use the command GO.
USBPORT
This command is only available on units with the optional USB
interface.
Syntax: port USBPORT
Instructs the digitizer to redirect input or output from port port to the
USB interface. You can then attach the USB port to your computer
with a suitable cable, where it will appear as an additional serial port
with a significantly faster data transfer rate. The value for port can be:
•
0, for the DATA OUT port;
•
1, for the GPS port; or
•
2, for the DATA IN port.
