5. INSTALLATION
All Jupiter-MM-SIO power supplies are load tested prior to shipping. The supplies ship with all the external
connectors required to start using your supply immediately. Any connector not needed can be removed.
1. Select the serial port base addresses using J9. Refer to page 9 for instructions.
2. Select the serial protocol for each serial port using J7 and J8.
3. Select the interrupt levels desired for each serial port using J10 and J11.
4. Connect a DC source to the Main power connector J4, or to the Auxiliary connector J5. The supply will
operate with input voltages from 7 to 30VDC.
CAUTION: VOLTAGES ABOVE 31V WILL BE SHUNTED TO GROUND THROUGH THE TRANSIENT
VOLTAGE SUPRESSOR (TVS). THE TVS IS RATED FOR 1,500 WATT SURGES, BUT IT MAY BE
DAMAGED BY SUSTAINED VOLTAGES ABOVE 31V.
5. Once the input voltage is in the valid range, verify that the power output indicator LEDs in the lower left
corner are illuminated. This verifies your input power connections and the supply are fully functional.
Note that only indicators corresponding to the voltages available on the supply will be lit. On the dual
output version, the –5V and –12V LEDs may be present on the board but will not be lit.
6. Power down the supply. Plug the supply into your PC/104 stack. Your system is ready to use.
