Type/Description

nDmm

int

Identifies the DMM. DMMs are numbered starting with zero.

iTest

int

Test type. 0: Basic Read/Write. 1: Toggle Reset line iNumber

times. 2: High Speed Guard Crossing stimulation. 3: Guarded
controller communication test. 4: Guard Crossing loopback test. 5:
High Speed Guard Crossing test (SM2064).

iNumber

int

Number of tests to be repeated.

Return Value

Integer error code.

Value

Meaning

DMM_OKAY

Operation successfully completed.

Negative Value

Error code

Example

int i =

GrdXingTest(0, 1, 3); // Test Guarded controller

5.9 Error Codes

Operation of the DMM may be impaired, should be aborted or is not possible following an Error. Use the

DMMErrString()

function, to retrieve the string describing the error.

DMM_OKAY

// no error

DMM_E_CAL

-1

// cannot open the calibration file at the specified location.

DMM_E_INIT

-3

// DMM must be initialized in order to execute the operation.

DMM_E_IO

-4

// I/O Error, DMM not responding

NOT_FOUND

-5

// DMM was not detected PCI bus

DMM_E_CAL_R

-6

// Not found a valid calibration record in specified file.

ERR_AD_HW

-7

// H/W Error, the A/D does not respond.

ERR_HW_INIT

-8

// H/W error, can't access H/W to initialize it. May be due to bad address

NO_CAL_RECORD

-9

// can't find a cal record for for this DMM in the specified cal file.

ID_HW_ERR

-10

// Can't read ID from DMM

GUARD_COM

-12

// Communication error with DMM uP

TIMEOUT

-13

// process timed out Error

GUARD_XING

-14

// Guard crossing is broken

CONTROLR_COM

-15

// Microcontroller communication error

OVERRUN

-16

// Communication Overrun error

FRAME

-17

// Communication Frame error

RCV_FIFO

-18

// Com receive Fifo error
