Symbols
Symbols (values), defined starting below, are used throughout the discussions of the
GSS-initiated messages that begin below and the command and response table that
begins on page 22. The symbols represent variables in the GSS-initiated messages and the
command and response table fields.
] = CR/LF (carriage return and line feed) (hex 0D 0A)
} = Carriage return (no line feed, hex 0D)
| = Pipe (can be used interchangeably with the } character)
• = Spacecharacter
E = Escape key (hex 1B)
W = Can be used interchangeably with the E character
X! = Image file name Image name with file extension (*.bmp or *.jpg)
(Up to 240 alphanumeric characters with no spaces)
X@ = Status:
On / off 0 = off 1 = on
Busy 0 = free 1 = busy
Cut / dissolve 0 = cut 1 = dissolve
Pass-through 0 = pass-thu 1 = no pass-thru
X# = Time 00 – 50 (0.0 to 5.0 seconds) for RGB delay and dissolve duration
000 – 300 seconds for slide show interval
X$ = Auto-switch / slide show 0 = off 2 = on / still
1 = off / show 3 = on / show
X% = Resolution 0 = 640 x 480 10 = 1366 x 768
1 = 600 x 600 11 = 1365 x 1024
2 = 852 x 480 12 = 1400 x 1050
3 = 1024 x 768 13 = 480p
4= 1024 x 852 14 = 576p
5 = 1024 x 1024 15 = 720p
6 = 1280 x 768 16 = 1080i
7 = 1280 x 1024 17 = 1080p
8 = 1360 x 765 18 = 1280 x 800
9 = 1365 x 768 19 = 1440 x 900
X^ = Refresh rate 0 = 50 Hz 3 = 96 Hz
1 = 60 Hz 4 = 100 Hz
2 = 72 Hz 5 = 120 Hz
X& = Sync format 0 = RGBHV 1 = RGBS
X* = Sync polarity 0 = H– / V– 2 = H+ / V–
1 = H– / V+ 3 = H+ / V+
X( = Front panel Lock mode 0 = unlock 1 = partial lock 2 = complete lock
X1) = Event number 00 through 99
X1! = Event buffer 0 = Receive 1 = User 2 = NVRAM
X1@ = Even buffer offset 00 through maximum buffer size
X1# = Event data size b = bit S = short (16 bits)
B = byte L = long (32 bits)
NOTE: The
X1#
parameter is case sensitive.
X1$ = ASCII digits representing the numeric value of the data element read from the event buffer (leading zeroes are suppressed)
X1% = Event status fields Event type
Event state
Event paused
Error status
