7. Known problems / issues
The following issues for the APC620/PPC700 devices are known:
• No support for IDE-based slide-in drives. Only USB slide-in drives are supported.
• Graphics Engine 2 (GE2) interface not supported. Only GE1 and analog RGB are
supported.
• In Windows XP, the Windows Standby mode is not supported in combination with the
add-on hard disk (5AC600.HDDI-05 and 5AC600.HDDI-06) in IDE Slave Only mode. A
blue screen or Windows crash can occur sporadically when returning from Windows
Standby mode. Windows Standby mode will function if a CompactFlash card is
connected to the IDE Master in addition the HDD on the slave slot. The same problem
also occurs if the "Turn off hard disks" function is activated in the Power Options in the
Control Panel (must be set to "Never").
• If the Intel GMA driver (Graphics Media Accelerator) is installed in the system (e.g. in
Windows XP), then an analog RGB monitor will always be detected, regardless of
whether one is connected or not.
• Using two different types of CompactFlash cards can cause problems in Automation PCs
and Panel PCs. This can result in one of the two cards not being detected during system
startup. This is caused by varying startup speeds. CompactFlash cards with older
technology require significantly more time during system startup than CompactFlash
cards with newer technology. This behavior occurs near the limits of the time frame
provided for startup. The problem described above can occur because the startup time
for the CompactFlash cards fluctuates due to the variance of the components being used.
Depending on the CompactFlash cards being used, this error might never, sometimes or
always occur.
• During daisy chain operation of multiple AP800/AP900 devices via SDL, it's possible that
the touch controller status shows a red "X" in the Control Center applet for the touch
screen driver when the touch controller is detected. The functionality of the touch system
is not affected by this. This can be avoided by setting a panel locking time of 50 ms. The
panel locking time can be configured with the B&R Key Editor.
