Warranty
•
Applying any negative voltage (< 0V) or positive voltage above +5V (> +5V) to one of the 64
analog inputs (JP1 – JP8 ) will destroy the circuit !
•
If potentiometers and/or switches are connected between GND and +5V of USB64 as
described in this manual no problems will occur.
•
When external control voltages are connected to USB64 the user has to pay attention that
the voltages applied are strictly within GND and +5V referenced to GND of USB64 !
•
Do not solder directly to any of the pin headers but use female connectors to make the
connections between USB64 and the potentiometers, switches or voltages. A cable set that
contains all required connectors and cables is included with USB64.
•
Carry out all connections in the off-state of USB64 (i.e. when powered-off only) !
•
Do not power on USB64 before all 64 analog inputs are connected. Do not leave analog
inputs unconnected !
•
USB64 electronics is an electrostatic sensitive device. Avoid any electrostatic charges ! Do
not touch the inputs with your fingers !
•
Avoid short circuits !
•
Ignoring any of these items will cause warranty loss !
•
We are not responsible if devices connected to the USB64 connector (e.g. computers) are
damaged because one or more of these remarks have been ignored. In particular one has
to pay attention to make no short circuit at the USB connector (e.g. by screws or other
conductive material).
•
Return of the USB64 within the 2 weeks return time limit (valid only in Germany) is only
possible if all these items have been met. Return of used cable sets is not possible. We
also cannot take back modules that have been soldered by the user.
