2.3.3 Output Power Connector
Output power is available for non-PC/104 use via connector CN2.
- Terminal 1: +5VDC output
- Terminal 2: Common
- Terminal 3: +12VDC output (optional)
- Terminal 4: -12VDC output (optional)
- Terminal 5: -5VDC output (optional)
2.3.4 Battery Power Connector (Optional)
The batteries are connected to the screw terminal block, CN3. The V104 accepts DC battery
voltages in the range of 8V to 30VDC through the Battery Power Connector. Two external signals
can be connected to the battery terminal block for use by add-on modules plugged into the
mezzanine header connectors. Connect to the V104 Battery Terminal Block as follows:
- Terminal 1: Common of battery
- Terminal 2: Positive Battery Terminal
- Terminal 3: External signal 1
- Terminal 4: External signal 2
Note: When optional Plug-IN Boost regulator (VR3) is ordered, batteries or external signals cannot
be connected to CN3. See section 2.3.5
2.3.5 Onboard DC “Boost” Converter (Optional)
Three optional converter “boost” pumps (model NMH05XXS, XX = output voltage, +5V, +9V, +12V,
+15V) can be installed on the V104. The NMH charge pumps have a maximum 2 watt capacity, but
require a minimum load of 10 percent for proper operation.
The –5V output is generated by installing a NMH0505S in location VR4 and adding capacitor C7.
The –5V output is available on the PC/104 bus (B-7) and on connector block CN2, terminal 4.
The third optional converter is used for generating custom voltages, which is installed in location VR3
and adding capacitors C4 and C8. The NMH charge pumps have an isolated positive and negative
output. By referencing (connecting) the charge pump to other voltages, the user can create +/-
supplies, elevated and negative voltages (ie. The charge pump “0V” is not connected to the V104
common).
- Terminal 1: Common of battery
- Terminal 2: -V output
- Terminal 3: 0V
- Terminal 4: +V output
