Hi folks My 2 x BIII both unlock and mute on. Checking on board Trident Voltage as 1.VDD = 0.56V / LED light 2.VDD_XO=3.2V / LED light 3.DVCC=3.2V / LED light Trident 1.2V module testing R4=10R / R8=1M UNLOAD Vout <-> GND = 1.18V, Vin <-> GND = 5V R1 / 1.13V R2 / 0.78V R3 / 1.17V R4 / 0.09V R5 / 0V R6 / 0V R7 / 0.01V R8 / 1.17V R9 / 0.01V LOADED Vout <-> GND = 0.57V, Vin <-> GND = 5V R1 / 1.13V R2 / 0.78V R3 / 1.17V R4 / 0.08V R5 / 0V R6 / 0V R7 / 0.01V R8 / 0.56V R9 / 0.01V My sensed that 1.2V module was wrong intuition!! Need help!! Thanks Edited by moderator Wednesday, May 23, 2012 4:16:40 PM(UTC)

It sounds like you are not delivering enough current to power the Tridents fully (the 1.2V module requires the most current, and will be the first one to cut out).
What are you using for a power supply?

[img]null[/img]Hi Brian My power supply is 9V Transformer -> Placid HD Black Label -> BIII Placid HD Voltage between TP_Vin+ <-> TP_CCS+ = 390mV TP_out+ <-> TP_SHUNT+ = 61mV BIII VDD= 0.58V VDD_XO = 3.28V DVCC = 3.31V Try to adj. current up to TP_Vin+ <-> TP_CCS+ = 560mV TP_out+ <-> TP_SHUNT+ = 120mV BIII VDD= 0.02V/1.19V but unstable VDD_XO = 3.29V DVCC = 3.30V My BIII included BIII/4 channel converter/sidecar, How much current for kits appropriately?? Thanks Brian for response Edited by user Wednesday, May 23, 2012 3:48:32 AM(UTC)
