6-176 Chapter 6: Programming
Model 801GC, 801GF & 801GX¥Rev. A
*WAI WAIt for completion suffix
Classification: Direct processor control
Command Syntax: <command>; *WAI
Limits: <command>
FMTU, IMGU, ALLU, BOOT, INIT, or SCAL
Query Syntax: None
Description: Normally, the generator returns a prompt immediately after either
an FMTU, IMGU, ALLU, BOOT, INIT, or SCAL command is
received - even before these commands have finished executing.
If the system controlling the generator must know when a
command has finished executing, use a semicolon to append
the suffix … ;*WAI. This causes the generator to wait until all
processes have been completed before sending the > prompt.
Other Required Cmds: The *WAI command is used as a suffix with the FMTU, IMGU,
ALLU, BOOT, INIT and SCAL commands.
Example: FMTL vga_m3 // Load a format from memory
// to buffer
IMGL SMPTE133 // Load the SMPTE RP-133
// image to buffer
ALLU;*WAI // Update hardware to current
// buffer contents and delay
// prompt until all done
XVSG Video Signal Gating
Classification: Format parameter setting
Command Syntax: XVSG <red mode>, <green mode>, <blue mode>
Limits: < mode>
0 = OFF
1 = ON
Description: The XVSG command determines which video outputs are active
when the format is selected. The same command controls both
the analog and digital video outputs.
Other Required Cmds: The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.
Example: XVSG 1 1 1 // Enable all color channels
FMTU // Update hardware to current
// buffer contents
