Figure 4-7
Circuit for Activating the Engine
The illustration below shows the circuit of activating the EM2037 from sleep mode. The right part of
Figure 4-8 is the receiving circuit on EM2037 decoder board. The left part of Figure 4-8 is provided for
design reference. The nWAKE signal comes from PIN11 of 12 PIN-FPC.
The host terminal can adjust the external circuit and its functions as per actual needs, but the external
circuit should match the circuit of the decorder board.
Figure 4-8
Circuit for Trigger
The illustration below shows the circuit which provides EM2037 with the trigger signal and thus enables a
read. The right part of Figure 4-9 is the receiving circuit on EM2037 decoder board. The left part of Figure
4-9 is provided for design reference. The nTRIG signal comes from PIN12 of 12 PIN-FPC.
The host terminal can adjust the external circuit and its functions as per actual needs, but the external
circuit should match the circuit of the decorder board.
