IOtech GPIB Command Associated MCC GPIB 488.2 Command

Hello TestSys

Limited functionality

Syntax

Hello INT WINAPI Hello(DevHandleT devHandle,

LPSTR message);

TestSys SendSetup(int board, short addresslist [],

short resultlist[])

Usage Notes

The Hello command, no longer to be used, verified communication with Driver488, and read

the software revision number. When the Hello command was sent, Driver488 returned a

string similar to the following: Driver488 Revision X.X (C)199X ...where X was the

appropriate revision or year number.

TestSys When this routine is executed, all of the devices identified within the

addresslist array are concurrently sent a message which directs them to perform their self-

test procedures. Each device returns an integer code indicating the results of its tests. This code

is placed into the corresponding element of the resultlist array. Note: according to the

IEEE-488.2 standard, a result code of 0 indicates the device passed its test. Any other value

indicates an error.

In the following example the command is telling the devices at addresses 6 and 7 [from Board

0] to perform their self-test procedures.

Example:

short addresslist[3] = {6, 7, NOADDR};

short resultlist[2];

TestSys(0, addresslist, resultlist);

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 63 64
