16. Power Connection
In some applications, the T-MOPSlcdSA is intended for use as a stand-alone module without a
backplane. You need to have a power connector available on the board for direct power supply. The
T-MOPSlcdSA is a +5V-only board. Peripherals can obtain additional voltage from the power
connector that is located next to the PC/104 bus. The additional voltages (+12V, -5V and -12V) are
not generated onboard the T-MOPSlcdSA.
16.1 Connector
The power connector is available as J9C (8 pins). To find the location of this connector on the T-
MOPSlcdSA board, please see the chapter “Connector Locations”.
The following table shows the pin-out.
Header Pin Signal Name Function
1 GND Ground
2 VCC +5V
3 BATT Battery
4 +12V +12V
5 -5V -5V
6 -12V -12V
7 GND Ground
8 VCC +5V
16.2 Power Pins
Every power pin on the power connector as well as on the PC/104 bus connectors is limited to a
maximum current of 1A per pin.
If a system using a T-MOPSlcdSA is only supplied from the power connector, the following
limitations apply:
Power Number of Pins Max. Current
VCC (+5V) 2 2A
+12V 1 1A
-12V 1 1A
-5V 1 1A
GND 2 2A
