INTRODUCTION The CPCI-H110 Passive Extender, can be used in any 6U CompactPCI H110 compatible system. The CPCI-H110 Passive Extender board has short circuit and over current protection for all voltages to protect the system motherboard, the power supply and the UUT from being damaged when an unknown board is plugged in. On-board current-to-voltage circuitry is designed in to allow current measurement for the +5V, +3.3V and +12V, using only a Voltmeter at the provided terminals.
EXTERNAL POWER SUPPLY An external terminal J5 is used for the external power supply input. However remember never to connect any supply to these inputs so long as you have JP4, JP5, JP6 and JP7 installed. In case you want to use the external supply as an input you must remove these 4 jumpers in order not to cause any conflict with the bus voltages. These jumpers are, however, independent from each other.
JUMPERS TABLE Description Jumper Utilization External power input J5 Inputs from external power supply Current measurement J3 Outputs to DVM -12V isolation from the system JP4 On = voltage from system, Off = from Ext. supply +12V isolation from the system JP6 On = voltage from system, Off = from Ext. supply +5V isolation from the system JP5 On = voltage from system, Off = from Ext.
SPECIFICATIONS Bus CPCI-H110, CompactPCI H110, 5V or 3.3V Extender Voltage Requirements: +5V, +12V & -12V @ 50 mA at no load. UUT Input Voltage Source: +5V, +/-12 V +3.3V Output Ratings: +5V +3.3V +/- 12V Output Voltage Drop: From the system bus or the external input, configurable by jumpers per voltage. From the system bus, on board regulator, or the external input, configurable by jumper. Jumper selectable to 10 Amp or 2 Amp limit. 3.
