Rocktron VooDu Valve Online User Manual page 94

If errors occur during transmission, the unit will display "RECEIVE ERROR" for transmission
errors and "XMEM ERROR" for internal hardware errors. Errors occurring in transmission
does not indicate that all of the received data is corrupted. Only the transmission string where
the error occurred is corrupted.
When receiving a Bulk Load, it is important that the data loaded to the Voodu Valve
is not transmitted faster than it was originally dumped from the Voodu Valve. If infor-
mation is sent too fast to the Voodu Valve, an error will occur.
When dumping information from a data storage device, such as an Alesis Data Disk,
it is necessary to perform the dump in sequence mode rather than sysx mode. Se-
quence mode will dump the information back to the Voodu Valve at the same rate as
it was received from the Voodu Valve. The Voodu Valve™ can receive a data dump at
about 65Hz (or about 1 byte every 15 milliseconds).
