ETS-Lindgren 2090 Controller - Manual (Page 122)

Appendix A: Model 2090 GPIB Command Reference Model 2090 Multi-Device Controller
SKN
Compatibility: 2090 (Firmware Rev 2.3)
Description: Instructs the device to begin seeking the specified target value in the negative
(down/counterclockwise) direction only. If the target is up/clockwise from
the current position, no motion occurs. The target must be located between
the current upper/clockwise and lower/counterclockwise limits. This
command is provided primarily to support continuous rotation turntables and
reverberation paddles. It allows forcing the seek of a position from a
particular direction. Thus, a SKN from 180.0 to 181.0 will rotate
counterclockwise to reach the target value.
Devices: Towers, Turntables
Syntax: SKN [+/-] XXX[.X]
+ Optional for positive values
- Necessary for negative values
XXX[.X] Decimal value for the seek target in centimeters for
towers and degrees for turntables.
In N1 mode .X is ignored
In N2 mode .X is optional.
Leading zeros are optional.
Example: CALL ibwrt (TowerUD%, "SKN 100.0") ' Instruct tower boom to seek
' 100.0 cm if CP > 100.0
CALL ibwrt (TableUD%, "SKN 260") ' Instruct turntable to seek
' 260 degrees if CP > 260 or
‘ in continuous rotation mode

SKP
Compatibility: 2090 (Firmware Rev 2.3)
Description: Instructs the device to begin seeking the specified target value in the position
(up/clockwise) direction only. If the target is down/ counterclockwise from
the current position, no motion occurs. The target must be located between
the current upper/clockwise and lower/counterclockwise limits. This
command is provided primarily to support continuous rotation turntables and
reverberation paddles. It allows forcing the seek of a position from a
particular direction. Thus, a SKP from 181.0 to 180.0 will rotate clockwise to
reach the target value.
Devices: Towers, Turntables
Syntax: SKP [+/-] XXX[.X]
+ Optional for positive values
- Necessary for negative values
XXX[.X] Decimal value for the seek target in centimeters for
towers and degrees for turntables.
In N1 mode .X is ignored
In N2 mode .X is optional.
Leading zeros are optional.
Example: CALL ibwrt (TowerUD%, "SKP 255.0") ' Instruct tower boom to seek
' 255.0 cm if CP < 255.0
CALL ibwrt (TableUD%, "SKP 260") ' Instruct turntable to seek
' 260 degrees if CP < 260 or
