The flat panel and CRT interface signals are routed to two separate connectors, both
displays can be driven simultaneously. The ability to drive both displays is dependant on
the particular timing parameters of the flat panel display. It is not always possible to
select appropriate clock rates to achieve an output on the CRT and flat panel displays.
The CRT output signals are routed to a 16-way 0.1” boxed header PL11. These signals
will normally be connected directly to a VGA compatible CRT monitor. A suitable cable
is provided as part of the SBC-GX1 development kit. The following table shows the
connection details for this cable. The CRT signals may be affected by noise and
therefore this cable should be kept as short as possible and should be routed away
from other signals to stop any crosstalk.
