A system using the T-MOPSlcdSA also can be supplied from the PC/104 bus connectors. If only
those supply voltages pins are used, the following limitations apply:
Power Number of Pins on
ISA Part
Max. Current
VCC (+5V) 4 4A
+12V 2 2A
-12V 2 2A
-5V 2 2A
GND 8 8A
Modules on the PC/104 bus consuming a higher supply current must provide power supply through
an additional connector.
The T-MOPSlcdSA does not replace a backplane. Use all power pins on the power connector
and on the PC/104 connectors to supply power to the T-MOPSlcdSA, and also use all additional
power connectors on additional I/O cards if your system exceeds the above limitations. It is not
acceptable to use only the power pins of the PC/104 connector to supply power to the full PC/104
stack.
16.3 External Battery
You can connect an external battery to Pin 3 (BATT) of the power connector instead of Pin 9 of the
Keyboard connector. For more information refer to the Keyboard and Feature Interface section.
Notes: The two battery inputs are protected against each other by diodes.
16.4 Configuration
The T-MOPSlcdSA is equipped with an Advanced Power Management system (APM). You can
configure lots of options for power-saving states such as doze/sleep, standby, and suspend state.
You can specify wake-up events that bring the system back to full-on state. Please refer to the
“Power Menu” section in the “Appendix B: BIOS Operation” chapter.
