SYNCHRONIZATION WITH A PC

1. H8 DSP functioning problems
- If, while tuning the system with a laptop PC, the H8 DSP should present any functioning problems, try to
disconnect the laptop PC power supply cable. In this way, with the laptop PC working on battery power, a
possible voltage difference in USB ground between car ground (H8 DSP) and earth (PC) can be avoided.
2. The H8 DSP does not connect to the PC software
- If, while tuning the system with a laptop PC, the H8 DSP is switched off and then on again, the connection is
lost and the software can not "finalize" the selected setup. If you do not want to lose the modifications and
setup previously selected, proceed as per the following steps:
a- save the setup as a file on the PC using the function FILE / SAVE SETUP;
b- exit the software;
c- turn on the H8 DSP;
d- launch the software again;
e- load the setup file again using the function FILE / LOAD SETUP.
3. The H8 DSP does not respond
If, while tuning the system with a laptop PC, the H8 DSP does not respond, proceed as per the following steps:
a- Spegnere l'H8 DSP: premendo la manopola del DRC, oppure scollegando il Remote IN, o anche scollegando
per un istante il cavo di alimentazione.
b- Salvare il setup in un file sul PC tramite la funzione FILE / SAVE SETUP.
c- Uscire dal software.
d- Accendere l'H8 DSP.
e- Riavviare il software.
f- Ricaricare il setup salvato tramite la funzione FILE / LOAD SETUP.
4. Settings not stored
In order to successfully complete the H8 DSP setup and not lose the settings performed, remember to store the selected
settings. Select File from the main software menu via the PC and then choose Finalize to H8 DSP.
