Additional Functions
Line monitor function
The states of all control lines (IFC, AT N, SRQ, REN, EOI, DAV, NRFD, and NDAC) can be read. The
latch data can also be read.
T he states of the data lines (DIO1 to DIO8) can be read on the GP-IB(PCI)F and GP-IB(LPCI)F.
Communication using FIFO memory
T he board can use on-board FIFO memory for communication. As the board controls this form of
communication, it can be performed at high speed irrelevant to the PC’s CPU speed.
Note, however, that the actual communication speed is set to the speed of the slowest device in
compliance with the GPIB standard.
Analyzer function (GP-IB(PCI)F, GP-IB(LPCI)F)
The state transition of all lines in the GPIB cable can be analyzed by using the on-board FIFO memory.
(A maximum of 64K data items can be collected.)
T his function can be used to locate the cause of a failure or to check data flowing on lines.
T he function is provided by the analyzer utility (Analyzer.exe).
Open the Start Menu, then select “ CONTEC API-PAC(W32)” – “ GPIB” – “ GPIB ANALYZER”.
Otherwise, directly execute “ Program Files\API-PAC(W32)\GPIB\ANALYZER\Analyzer.exe”.
Running Method
(1) Install the board on your PC according to Step 2 “ Setting the Hardware” and Step 3 “ Installing the
Hardware” in Chapter 2 “ Setup”.
After having installed the board, connect the board to an instrument for analysis. T he board can
communicate with the instrument while executing analysis.
Example 1 of Connection:
3765
One board communicating the instrument while analyzing
Example 2 of Connection:
PC1
3765
PC2
PC1: Only the analyzer is executed.
PC2: Communicating with the measuring instrument
