Title: Universal Ultra Test Taps Post by: jbshocks on September 16, 2011, 01:31:09 PM In case anyone ever wondered what the colored beads are for on the Universal Ultra board they are for testing. The picture shows the "beads" Their use is as follows:
1. CH1 white Ground 2 2. CH2 Blue VCC2 3. CH3 Orange +30 volts 4. CH4 Black Ground 1 5. Ch5 Yellow Vcc1 6. CH6 Green Ground 3 7. Ch7 Red +12 volts. I don't have Vcc 1 and 2 voltage handy. Maybe Uniman has it handy. One word of warning. The ultra does not have a shared ground. The 3 grounds are unique.

I'm finding Vcc 1, yellow, at 5 Vdc and Vcc 2, blue, also 5 Vdc. Title: Re: Universal Ultra Test Taps Post by: jbshocks on September 16, 2011, 11:11:32 PM was that from a meter test? If so what ground did you use?

I made a test station with power supply, backplane and mpu board. Used the white ground with the blue tap and the black ground with the yellow tap. I don't see where the Vcc 2 gets used? |
