Notes:
• The connection between the reader and controller should use 8 wires STP cable. The
diameter should be over 24 AWG (0.206mm). The distance should be less than 100M.
• To transmit the data successfully, the Data 0 and Data 1 should use the same pair, e.g.
Green and Green/white (pair of wires in the cable).
• When the transmitting distance is over 60M, the Data 0 and Data 1 wires should be
paralleled up with unused pairs to reduce the resistance. For example, if we have 4 free
wires, then 2 should be shortened to Data0 and 2 should be shortened to Data1.
• Do not use the same power supply source for the door lock and the reader to avoid
EMF (electromotive force) interference.
