3.8.4 Failing
Transfers
A failing transfer can have several causes:
•
Incorrect COM port selection, try another COM port (i.e. select COM 1 or COM 2).
•
The SMT-200 to Docking Station cable is not connected properly.
•
Docking Station's power is off: the SMT-200 will be switched on however, but the
communications circuit needs power.
•
PC is not ready, i.e. other processor tasks are taking too long, causing time-out errors.
Preferably run the Docking Station software under DOS if transfer problems are found. It has
been proved that it will work successfully under Windows 3.1. Windows 95 will run the
software but this has been found to be system dependent. Try running the software in MS-
DOS mode.
•
Some problems have been encountered with incompatible serial interface controllers on
certain computers. If all the above fails then try a different computer, if available.
