2.1
Parallel port connection
The ST7 EPB communicates with your host PC (running STVP7) via a parallel port
connection.
Most communication failures between the host PC running STVP7 and your programming
board stem from problems in the parallel port connection.
To prevent communication problems, when setting up your parallel port connection:
●
Configure your PC’s parallel port suing either the Centronics, EPP, ECP, or bidirectional
parallel port configuration.
●
Use the parallel cable provided with your kit—using a longer parallel cable may cause
malfunctions.
●
Connect the cable directly between the host PC and the programming board—the
insertion of additional cables or switch boxes between the host PC and the
programming board may cause malfunctions.
●
Remove any parallel port dongles.
