systems are supported. PG4UWMC can handle from 1 to 8 programmer sites. One
programmer site means one ZIF socket module.
Troubleshooting
Serial numbers
For successful using of multiply programmers, correct serial numbers must be specified for
each used programmer in panel Serial numbers. If there is empty field for serial number,
application PG4UW for the programmer Site won't start.
When PG4UWMC application is searching for connected programmers in "Search for
programmers" dialog, serial numbers of programmers are detected automatically. User does
not need (and can not) specify serial numbers by himself.
Communication error(s) while searching for programmers
If some kind of communication error(s) occurs, please close all PG4UW applications and
PG4UWMC and then start PG4UWMC and click button "Connect programmers" to start
PG4UW applications for each Site and connect programmers.
All programmers are connected correctly but unstable working
If communication with programmers is lost randomly during device operation (for example
device programming), please close other programs, especially programs which consumes
large amount of system resources (multimedia, CAD, graphic applications and so on).
Note: We also recommend using computer USB ports placed on back side of computer and
directly connected to motherboard, because computer USB ports connected to computer
motherboard indirectly - via cable, may be unreliable when using high speed USB 2.0 transfer
modes. This recommendation is valid not only for programmers, but also for other devices.
