AXB-PT10/30 PosiTrack Camera Controllers
Positional Commands (Cont.)
GL
Turns on the specified
output at the current
speed until the speci-
fied position as read by
the POT input is
reached.
This command can be used for motor mode and servomotor speed modes.
Syntax:
"’G<output>L<position>’"
Command forces output to go to a preset position using the POT input as a
reference. (Positions 0-65,535 are available using the 'AD MODE x 10' command.)
Variables (See
Parameters - Send_Commands
section on page 36):
G - output = 3 - 4
L - position = 0 - 255 or 0 - 65535
Example:
SEND_COMMAND CAM,"’G3L100’"
Sets ZOOM to search for position 100 as referenced by the ZOOM POT input.
GS
Sets the current speed
for future and current
Send_Commands and
channel commands.
This command is used for motor mode and servomotor speed mode applications.
Syntax:
"’G<output>S<speed>’"
Variables (See Parameters - Send_Commands section on page 36):
G - output = 1 - 5
S - speed = 0 - 127
Example:
SEND_COMMAND CAM, "’G1S64’"
Sets PAN to speed 64 (50%) for current and future commands.
The G1 and G2 commands are used for all modes. The G3, G4, and G5 commands
are for the Motor mode ONLY.
PLT
Ramps specified out-
put voltage from cur-
rent level to a specified
level or percentage at
the current rate or
optionally in a specified
amount of time.
This command can be used only for servomotor positional mode applications.
Syntax:
"’
P<output>L<level >[T<time >]
’"
Variables (See Parameters - Send_Commands section on page 36):
P - output = 3 - 5
L - level = 0 - 255 or 1 - 100%
T - time = 0 - 255 (in tenths of a second)
Example:
SEND_COMMAND CAM,"’P3L50%’"
Ramps zoom output to 50% (mid-voltage) at current rate.
SEND_COMMAND CAM,"’P4L255T30’"
Ramps FOCUS output to 255 in 3 seconds.
