2.11.1 CRT display connector (CN13)
CN13 is a 16-pin, pin head housing connector. Please use the
VGA cable (provided with your kit) to convert the pin head
housing connector into a connector for conventional CRT
displays.
Detailed information on pin assignments for CRT display
connector CN13 is given in Appendix C.
2.12 Reset button connector (CN13)
If you install a reset button, it should be a single pole switch
rated at 5 V. Momentarily pressing the button will activate a
reset. For reset button pin assignments, please see Appendix
C.
2.13 Panel Back-light power (CN15)
This supplies main power to the PCM-3341 (+5 V), and also 12 V power
to the backlight connector.
2.14 PS/MS connector (CN17)
The PCM-3341 board provides a pin head keyboard connector, which
supports both a keyboard and a PS/2 style mouse. In most cases, espe-
cially in embedded applications, a keyboard is not used. If the keyboard is
not present, the standard PC/AT BIOS will report an error or failure dur-
ing the power-on self test (POST) after resetting the PC. The PCM-3341
board's BIOS standard setup menu allows you to select "Absent/Present"
for your keyboard under the Advanced CMOS Setup section. This allows
non-keyboard operation in embedded system applications without the
system halting during the POST. When "PS/2 mouse support" is enabled,
your PS/2 mouse is automatically detected by the system.
