Remote communications protocol
Version 1.2 Patch A
Each command string sent to the projector should start with character 0x0a and end
with character 0x0d. If you are using Windows Hyperterminal, then this will be taken
care of by the Ascii Setup described on the previous page.
Pre fi x each command with:
“[id],[user],[time],[date],[command priority],[projector id],[projector name],”
for example:
1234,external,16:37:31,01/04/2004,5,543210,DPL-123,
example lens command (close shutter)
1234,external,15:20:25,14/10/2004,5,543210,DPL-123,lens,move,write,s,c,0,0
example lens command (open shutter)
1234,external,15:20:30,14/10/2004,5,543210,DPL-123,lens,move,write,s,o,0,0
