GSS-initiated (unsolicited) messages
When a local event, such as a front panel operation or error
condition, occurs, the GSS responds by sending a message to
the host. The GSS-initiated messages are listed in the following
pages. The messages are underlined.
The GSS does not expect a response from the host, but the host
program may request a new status.

]
The GSS issues the copyright message when it first powers on.
Vx.xx is the firmware version number.
X1^
= Event data to write
X1&
= Number of bytes to read
X1*
= Event status fields: Event type
Event state
Event paused
Error status
RcvBuff_startptr
RcvBuff_endptr
UsrBuff_startptr
UsrBuff_endptr
X1(
= ASCII digit(s) representing the numeric value of the data element read from
the event buffer (leading zeroes are supressed)
X2)
= Port number 00 to 99 (00 = all ports)
X2!
= Baud rate 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 14400, 19200,
28800, 38400, 57600, 115200 (9600 is default)
X2@

N Use the first letter only.
X2#
= Data bits 7 or 8
X2$
= Stop bits 1 or 2
X2%
= The number of seconds (in 10-second steps) before timeout on the IP connec-
tions: (min = 1, max = 6500, default = 30 [300 seconds]). If no data is received
during the timeout period, the Ethernet connection is closed. Applicable to
Ethernet connection only; when connected via the RS-232 port, only the global
timeout commands apply.
Image selection
Take
]
Bsy1
]
Bsy0
]
The GSS issues the above sequence of commands when a front
panel image selection operation or a slide show image change
occurs.
• The Take message indicates the change of output image.
• The Bsy1 message indicates to the connected control
device that the GSS is busy processing the cut or dissolve
transition and is unable to respond to input commands.
• The Bsy0 message indicates that the GSS is no longer busy
and can respond to input commands.
Switch effect
EffX#
]
The GSS initiates the Eff message when a front panel change in
the image switch effect takes place.
DurX#
]
The GSS initiates the Dur message when a front panel change in
the dissolve duration takes place.
Output configuration
N
The Output Configuration settings apply only to
the output of still images stored in the GSS; the
RGB Pass-through video is output exactly as it is input.
RteX%*X^
]
The GSS initiates the Rte message when a front panel change in
the output resolution takes place.
TpoX&
]
The GSS initiates the Tpo message when a front panel change in
the output sync format takes place.
PolX*
]
The GSS initiates the Pol message when a front panel change in
the output sync polarity takes place.
DlyX#
]
The GSS initiates the Dly message when a front panel change in
the RGB delay interval takes place.
