Chapter 18
A system using the MOPSlcdLX also can be supplied from the PC/104 bus connectors. If only those supply
voltages pins are used, the following limitations apply:
Modules on the PC/104 bus consuming a higher supply current must provide power supply through an
additional connector.
Note:
The MOPSlcdLX is not a replacement for a backplane. Use all power pins on the power connector and on the
PC/104 connectors for power supply to the MOPSlcdLX, and also use all additional power connectors on additi-
onal 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 for power supply to the full PC/104 stack.
18.3 External Battery
You can connect an external battery to Pin 3 (BATT) of the power connector instead of Pin 9 of the KBD
connector. For more information refer to the Keyboard chapter of this manual.
Note:
Pin 3 (power connector) and Pin 9 (KBD connector) are connected to the same signal. The pins are not de-
coupled, therefore do not connect two batteries.
