Re: EMXP error codes

2012-03-06 by esynthesist

OK, the fact that Mac mode can be set by EMXP and the EmuSer means that the asynchronous mode works.
The DC voltages seem OK.
Do you have an oscilloscope to check the clock signal on pin 9 ? Is it OK (frequency (500kHz), signal level) ? 
What capacitors did you use for C4 and C5 ?
What revision of Emulator II are you using ?
Especially rev 1 emulator-II samplers are sensitive to these capacitors - they have been added to the EmuSer afterwards specifically for rev 1 E-II because without them the same error codes as you have appeared. Rev 0 emulators can work without these capacitors.
Maybe you can experiment with other values for these capacitors or skip these capacitors.
If this doesn't help neither, I will send you the terminal software and contact you via e-mail.
