Use SST to find out a variety of information about the current state of the projector. The single
broad-ranging request (ssT?) for all information triggers the return of a series of replies as if
multiple requests had been sent. In each of these status replies, P1 explains the general content
or topic in the reply, and P2 the individual details. To obtain status regarding one topic only,
specify the desired P1 parameter corresponding to that topic in your request—for example,
the request (ssT?0) will trigger general projector information only. For a specific single-status
inquiry, include both P1 and P2 in the request—for example, (ssT?4 2) asks whether the lamp
door is open or closed. Thus you can use the SST request command in 3 ways:
1)
(ssT?) returns all results along with descriptive text/data. The specifics
within each of the five status groups will vary from model to model and be
affected by options installed, software versions and other factors, thus a
general SST inquiry is a good way to establish exactly what status reports
are available for your projector.
2)
(ssT? x) where X = which Status Group 0-4 (P1). This request obtains all
results belonging to this status group.
3)
(ssT? x Y) where X = which Status Group 0-4 (P1), and Y= which Detail
0-varies (P2). This request obtains
for all projectors listed on page 3:
P1 = Status Group
0 = General Projector Model Information – model, serial#, resolution, factory
settings, etc.
1 = System Status – power on/off, lamp, hours of use, shutter, OSD, etc.
2 = Signal Information – source frequency, channel#, switching, etc.
3 = Operation Status – errors, temperatures, and interlocks
4 = Versions – h/w versions, s/w versions, h/w serial numbers, optional
modules

Use STD to select the video standard to use with the video input. If "auto" is selected (8) the
projector will automatically find the correct standard. If a request for standard is made and the
standard has been set to "auto" the return value will be preceded with an 'A'.
0 = PAL
1 = NTSC
2 = SECAM
3 = NTSC4.43
4 = PAL-M
5 = PAL-NC
6 = PAL-60
7 = NTSC
8 = Auto-select
