programmable.

It has automatic initialization. Interface parameters are set to default automatically when
starting using the interface. Parameters can still be changed by calling the initialization
routine.

Its DIP switch selectable wait states (0/2/4/6 wait states) to ensure the compatibility to very
high speed PC’s.

Its PCL-848A offers the connectors of the IEEE-488 standard white PCL-848B uses the 25
pin D type connectors for the IEC-625 standard.

Its own terminators can be assigned to each device on the IEEE-488 bus. (PCL-848C

3.5 GPIB Driver Selection
Two GPIB drivers are found from the Internet, one is NI 488.2 software, which is Beta version of
GPIB driver released by National Instruments in June 2003, the other is Simple GPIB driver (sgpib),
which can found in Author’s home page at
http://cip.physik.uniwuerzburg.dehttp://cip.physik.uniwuerzburg.de/~cip307/gpib/main.html. Both NI 488.2 and sgpib can be used to
drive PC-LAB GPIB Card on Linux, however, in this project, sgpib was chosen because of its
simpleness of installation and implementation.
The data flow of sgpib driver is shown below.
