TROUBLESHOOTING TROUBLESHOOTING
We really want you to enjoy our product. Nevertheless, problems can occur. In such cases please read
carefully all the enclosed documentation again. Probably you will find the needed answer right away.
Should the problem persist, please follow the instructions below.
COMMUNICATION ERRORS
- Programmer must be supplied correctly, so the green supply LED must be ON and the power
supply must be the one delivered with the programmer. To test the supply cable's physical
integrity twist it delicately and see if something changes.
- Update the control program, often a more recent version includes enhancements also in
communication reliability. Please refer to “FREE SOFTWARE UPDATES” paragraph for
more information.
- Programmer must be connected directly to parallel port, no data switch, hardware keys or port
duplicators can be put between PC and programmer.
- Parallel port must be completely dedicated to the programmer, under Windows it must not be
shared as a network resource and no printer driver must use it.
- The printer port where the programmer is connected must be configured as IEEE 1284 port. You
should check in the BIOS configuration of Your computer that the port is set correctly, or, if
You use a multi I/O card, assure that it can be configured and used as IEEE 1284.
- The parallel cable must be the one delivered with the programmer or a printer cable with all the
pins connected. To test the cable's physical integrity twist it delicately when PG4U/PG4UW
tries to connect to the programmer and see if something changes.
- Try to install programmer and PG4U/PG4UW on another computer. If your system works
normally on the other computer you might have a problem with the first one PC. Compare
differences between both computers.
- Try to set the parallel port as Centronics compatible. This may decrease communication
efficence but assures the greatest compatibility level Your PC can give.
READING OR PROGRAMMING PROBLEMS
- Assure the correct alignment of target device in the socket. Check the serigraph on the
programmer or see the adapter serigraph if using one.
- Target device name must be selected on PG4U/PG4UW before attempting to read or to program
it.
- Target device name and selected device on PG4U/PG4UW MUST BE EXACTLY THE
SAME ! If You attempted to program or to read a device with a name different or just similar
to the target device name You may have damaged both the target device and the programmer.
- Update the control program. Electronic manifacturers create new devices almost everyday so
it is essential to serch target device names in the latest version of PG4U/PG4UW. If You still
can't find Your target device please refer to paragraph “UNSUPPORTED TARGET DEVICE”.
- If the target device has never been programmed before or has been deleted it has returned to blank
state. Perform “Blank check test” through Device/Blank Check menu or the keyboard shortcut
