Common notes
too. If pins are outputs, then use of resistors saves a
programming time. Of course the isolation resistors R1, R2,
(R3) can be replaced by switches or jumpers, if necessary.
In that case, during the ISP programming of target device
the switches (jumpers) must be open. But the using of
switches (jumpers) adds a next manipulation time to
programming procedure.
Other
Attention to multitasking OS's (Windows
95/98/Me/NT/2000/XP). There is needful for regular running of
control program for any Dataman programmer that printer port,
on which is programmer connected, must be reserved for this
programmer only. Otherwise, any other program must not
simultaneously to use (or any way to modify) this printer port.
PG4UW SW can handle all modes of LPT port (full IEEE 1284
support), thus you don't need to configure LPT port for
connection of Dataman programmers.
Please don't move Info window during BUSY LED is on -
watching circuit can be activate to switch the programmer in
safe status as in case communication PC-programmer error.
LPT port driver
For programmers connected through parallel LPT port, control
program requires correctly installed LPT port driver. LPT port
driver installation and uninstallation is made automatically by
installation program. Normally there are no problems with the
driver. But sometimes driver can not be initialized correctly. It is
especially in the case that no LPT1 port is present in the
Windows NT/2000/XP operating systems. When the LPT port
driver is not initialized, control program can not detect any LPT
ports in the system.
LPT driver requires port LPT1 to be present in the operating
system. Please check the parallel port LPT1 is present in the
system.
The short description, how to see LPT ports present in
operating system:
1. click to "Start" menu
2. click with right mouse button to "My computer" item and
select menu "Properties
3. in the "System properties" dialog select "Hardware"
page and click to "Device manager" button
