Pins and +5 volts from the power supply?
2001-12-23 by Bret Truchan
Season's greetings everyone! I'm experimenting with creating my own modules and ran into a big unknown. The rack frame and power supply should supply +5 volts and +/- 12 volts. However, it *seemed* (and I probably did something wrong) that the +5 volts was not there. To check, I built a simple circuit with a resister, and used a volt meter to check the presence of the +5 volts. Nada. This seems strange, because all my modules are working just fine. The LED next to +5 volts isn't on. The LEDs near +/- 12 volts is on. Perhaps those LEDs turn on only when a module uses that power source? Does anyone have experience in tapping into this +5 volt source? Can someone instruct me how to build a simple circuit that uses this power source? Much thanks! I'm obviously more ambitious than experienced... - Bret _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
