Figure 6: using the digital inputs
Examples:
-
B0=0V, B1=5V, B2=5V, B3=5V -> antenna channel 1 active
-
B0=5V, B1=0V, B2=5V, B3=5V -> antenna channel 2 active
-
B0=5V, B1=0V, B2=5V, B3=5V -> antenna channel 3 active
-
B0=5V, B1=5V, B2=0V, B3=5V -> antenna channel 4 active
-
B0=0V, B1=5V, B2=0V, B3=5V -> antenna channel 5 active
-
B0=5V, B1=0V, B2=0V, B3=5V -> antenna channel 6 active
-
B0=0V, B1=0V, B2=0V, B3=5V -> antenna channel 7 active
-
B0=5V, B1=5V, B2=5V, B3=0V -> antenna channel 8 active
After switching to a new antenna channel the ARE i2 can read the transponder in the antenna field.
Attention!
Be sure that the ARE i2 is not reading (GT or MD0) while the AMP 4/8 switches the channel. The
reader can hang up or can be damaged.

Startup and testing the AMP 4/8
Connect the reader via cable with the serial interface (COM) from your notebook or pc.
Connect the reader with your power supply (9..30V DC). Look after the polarity!
Switch the power supply on. The yellow LED of the AMP starts to blink.
