To replace obsolete components typically requires a great deal of software effort because there are
often many test program sets that need to be changed. VXI Technology has greatly simplified this
task by developing a translation driver set for the VX4802. The translation driver takes function
calls to the VX4802 and converts them to VTI4802 calls. The result is that any code written to
operate with the VX4802 can be used, without modification, when an VTI4802 is installed in its
place.
