NXC-VAI4 Send_Commands (Cont.)

Command Description

Sets one of the two "set

point" variables "I/O <x>

SET POINT H|L"

(high or low).

These variables are used to calculate calibration parameters for I/O <x> (input

or output). Receiving this command with no voltage specified returns the

specified set point to the default value.

Syntax:

SEND_COMMAND <DEV>,'P<I/O>Z<VOLTAGE>H|L'

Variables:

I/O: Any input or output ('1', '2', '3', '4', '5', '6', '7', '8' plus '0' for EREF)

VOLTAGE: The current actual/measured voltage at the I/O.

Examples:

SEND_COMMAND <DEV>,'P1Z0.5VL'

Creates a low-end calibration point associating the current D/A code with 0.5

volts.

SEND_COMMAND <DEV>,'P1Z11.5VH'

Creates a high-end calibration point associating the current D/A code with

11.5 volts.

SEND_COMMAND <DEV>,'P0Z0.1VL'

Creates a low-end calibration point associating the current EREF A/D code

with 0.1 volts.

SEND_COMMAND <DEV>,'P1ZL'

Returns the Output 1 lower set point to its default.
