NXC-VAI4 Send_Commands (Cont.)
Command Description
PN
Sets the value of either the
minimum output voltage
allowed for an output, or the
minimum position voltage
expected for an input.· Voltage settings are rounded to the nearest D/A or A/D code. Voltage settings
for Outputs are absolute levels and are unaffected by any software scaling
functions. Negative voltages are not valid for Input 3.
Syntax:
SEND_COMMAND <DEV>,'P<I/O>N<LEVEL VALUE>'
Variables:
I/O: Any input or output ('1','2','3','4','5','6','7','8')
LEVEL VALUE: -12.000V to +12.000V
Examples:
SEND_COMMAND <DEV>,'P1N5.023V'
Sets the minimum output level for Output 1 to 5.023V.
SEND_COMMAND <DEV>,'P1N-5.023V'
Sets the minimum output level for Output 1 to -5.023V.
SEND_COMMAND <DEV>,'P7N5.023V'
Sets the minimum of the expected input range for Input 7 to 5.023V.
PR
Sets the CURRENT
OUTPUT <x> RAMP UP
TIME and/or CURRENT
OUTPUT <x> RAMP DOWN
TIME of the specified Output
where TIME is the time to
ramp the full range. It can be set to ramp both down to up and up to down or just down to up or just
up to down.
Syntax:
SEND_COMMAND <DEV>,'P<OUTPUT>R<TIME>[U|D]'
Variables:
OUTPUT: Any Output '1', '2', '3', or '4'
TIME: 0 - 255 in 0.1 second increments
U/D: Ramp Up (U) or Down (D)
Examples:
SEND_COMMAND <DEV>,'P1R25'
Sets CURRENT OUTPUT 1 RAMP UP TIME" and "CURRENT OUTPUT 1
RAMP DOWN TIME" to 2.5 seconds each for full range travel.
SEND_COMMAND <DEV>,'P2R75U'
Sets CURRENT OUTPUT 2 RAMP UP TIME to 7.5 seconds for full range
travel, CURRENT OUTPUT 2 RAMP DOWN TIME remains unchanged.
SEND_COMMAND <DEV>,'P2R50D'
Sets "CURRENT OUTPUT 2 RAMP DOWN TIME" to 5 seconds for full range
travel; "CURRENT OUTPUT 2 RAMP UP TIME" remains unchanged.
PU
Sets the level to which this
Output is set immediately
after power-up and before
any Output is commanded. Syntax:
SEND_COMMAND <DEV>,'P<OUTPUT>U<LEVEL VALUE>'
Variables:
OUTPUT: Any Output ('1', '2', '3', or '4')
LEVEL VALUE: 0-255
Example:
SEND_COMMAND <DEV>,'P1U127'
Sets the power up output level for Output 1 to 127.
