Power supply
The AMP 4/8 needs 9..30 V/DC. Be sure that the SAB cap is mounted rightly when you switch on
the power supply. Do never remove the SAB cap when the power supply is active. Otherwise the elec-
tronic can be damaged.
It is very important to power the AMP with a clean ground (without any electrical interferences).
The best way is, to use the same ground as the reading system.

Interface
The AMP has a RS232 or USB interface. The standard parameters are: 19200 baud, 1 startbit, 8
databits, 1 stopbit, no paritybit.
