Chapter 3 Software Overview

Set_DAQ_Device_Info

Selects parameters pertaining to the device

operation.

Timeout_Config

Establishes a timeout limit that is used by

the synchronous functions to ensure that

these functions eventually return control to

your application. Examples of synchronous

functions are

DAQ_Op

DAQ_DB_Transfer

,and

WFM_from_Disk

Software-Calibration and Device-Specific Functions

Each of these software-calibration and configuration functions is specific

to only one type of device or class of devices.

Refer to the NI-DAQ Function Reference Online Help file to determine

which functions your device supports.

AO_Calibrate

Loads a set of calibration constants into

the calibration DACs or copies a set of

calibration constants from one of four

EEPROM areas to EEPROM area 1. You

can load an existing set of calibration

constants into the calibration DACs from

a storage area in the onboard EEPROM.

You can copy EEPROM storage areas

2 through 5 (EEPROM area 5 contains the

factory-calibration constants) to storage

area 1. NI-DAQ automatically loads the

calibration constants stored in EEPROM

area 1 the first time a function pertaining to

the AT-AO-6/10 is called.

Calibrate_1200

Calibrates the gain and offset values for

the 1200/AI devices ADCs and DACs. You

can perform a new calibration or use an

existing set of calibration constants by

copying the constants from their storage

location in the onboard EEPROM. You can

store up to six sets of calibration constants.
