I built another Case :
and wanted to use the uZeus with a 3000 mA PSU Adapter. When i turned it on the -12v led didnt light up, but the other ones did. Some modules powered on, too but I quickly turned the PSU down because I feared of destroying anthing.
I also found something in the manual of the uZeus regarding the -12v rail:
"The –12V rail uses a switching regulator. This switching regulator needs to
have a minimum load of 100mA (out of 500mA) at any given time. The
uZeus has a factory setting to self consume this current. If your uZeus is
powering more than four (4) analog modules you can then disable this
setting if desired to make this 100mA available for use by your modules.
With the uZeus powered off, look for header J7 (located below the blue
resistor) and remove the jumper. Re-insert the jumper such that it comes in
contact with only one pin. Once reinstalled in the system, the uZeus will
provide the full 500mA of –12V power for your modules"
Do I just need to remove the jumper? If not, what are the best steps to debugging?
Thanks in advance!
