When connecting a clock/data reader, attach the reader's DATA output to the
positive line of the input 1 of the TEV-IB1 board. Attach the CLOCK output to the
positive line of the input 2. Combine negative lines of inputs 1 and 2 together and
connect them to the ground line of the reader. Leave JP4 jumper opened.
When connecting a Wiegand reader, attach the reader's W0 output to the positive
line of the input 1 of the TEV-IB1 board. Attach the W1 output to the positive line
of the input 2. Combine negative lines of inputs 1 and 2 together and connect them
to the ground line of the reader. Close the jumper JP4.
Most Wiegand readers have open-collector outputs, which means you may need to
install pull-up resistors on their W0 and W1 outputs.
The function of the JP4 is to combine the signals W0 and W1 -- this is required for
the EM1000's serial port operation in Wiegand mode.
Jumpers JP1-3 should be left open.
