6. INSTALLATION TIPS & CHECK POINTS
Please refer to information below to stably operate the LX006.
6.1 CHECK POINTS BEFORE INSTALLATION
6.1.1 CABLE SELECTION
(Figure: System configuration)
6.1.2 RECOMMENDED CABLE TYPE AND PERMISSIBLE LENGTH OF CABLE
* Thicker wires are required if you connect the reader with high current consumption.
6.1.3 READER CONNECTION
If you install the reader in a long distance between the ACU and the reader, you should be aware
there could be voltage drop between ends of GND wire. For example, if you connect a reader with
100mA current consumption at 100m distance (assume to using DC resistance of cable of
100Ω/100m) and the reader power is supplied from the ACU, the voltage drop of the GND wire will
be 1V. In this case, the Wiegand data signal cannot be measured lower than 1V.
