NXC-VAI4 Input Level Assignments
Level Description
1 8 bit field, returns the current output voltage code for Output 1 (range= 0 to 255).
2 8 bit field, returns the current output voltage code for Output 2 (range= 0 to 255).
3 8 bit field, returns the current output voltage code for Output 3 (range= 0 to 255).
4 8 bit field, returns the current output voltage code for Output 4 (range= 0 to 255).
5 8/16 bit field, returns the current input voltage for Input 1 (range= 0 to 255 or 0-65535, depending on the
ADMODE setting. See the AD MODE Send Command for details).
6 8/16 bit field, returns the current input voltage for Input 2 (range= 0 to 255 or 0-65535, depending on the
ADMODE setting. See the AD MODE Send Command for details).
7 8/16 bit field, returns the current input voltage for Input 3 (range= 0 to 255 or 0-65535, depending on the
ADMODE setting. See the AD MODE Send Command for details).
8 8/16 bit field, returns the current input voltage for Input 4 (range= 0 to 255 or 0-65535, depending on the
ADMODE setting. See the AD MODE Send Command for details).
NXC-VAI4 Send_Commands
Command Description
AD MODE Sets the format for data reporting to either 8 or 10 significant bits (16 bit format with 10 significant bits).
Even though the output is specified in the command, the format change really applies to the
corresponding input. Input level changes and commanded positions are in this format. The reporting of
the output levels is unaffected. The default format is 8 bits.
Syntax:
SEND_COMMAND <DEV>,'AD MODE <OUTPUT> 8|10'
Variable:
OUTPUT: Any Output ('1', '2, '3', 4')
Examples:
SEND_COMMAND <DEV>,'AD MODE 2 8'
Sets the reporting format for Input 2 to 8 bits. (0-255)
SEND_COMMAND <DEV>,'AD MODE 1 10'
Sets the input reporting format for Input 1 to 10 significant bits (0 - 65535)
DEFAULT Sets all card settings (except for calibration) back to original factory settings.
Syntax:
SEND_COMMAND <DEV>,'DEFAULT'
DEFAULT ALL Sets all card settings back to original factory settings.
Syntax:
SEND_COMMAND <DEV>,'DEFAULT ALL'
GAS Sets the slowdown distance and slowdown speed. When these variables have been set, and a GL
command is in progress, the speed output on Output <x> will be reduced to that specified when the
position as read on Output <x+4> is within the distance specified away from the target position.
Syntax:
SEND_COMMAND <DEV>,'G<OUTPUT>A<DISTANCE>S<SPEED>'
Variables:
OUTPUT: Any Output '1', '2', '3', or '4'
DISTANCE: 0-127
SPEED: 0-127
Example:
SEND_COMMAND <DEV>,'G1A127S127'
Sets Output 1 slowdown distance to 127 (max) at full speed.
