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 VX4801. The translation driver takes function
calls to the VX4801 and converts them to SM4801 calls. The result is that virtually any code
written to operate with the VX4801 can be used, without modification, when an SM4801 is
installed in its place.
All commonly used functions are supported in the translation driver set. For those functions not
supported, VTI includes the translation driver source code for custom modification or will add the
functions by request. A list of all tkvx4801 functions supported in the translation driver set are
listed in the following table.
