a.
Antenna connection
: remove the K61-40 and K61-04 antenna caps, and screw the 433Mhz frequency band "suction
cup antenna" on the product clockwise;
b.
Power connection
: connect the "
red wire
" of the "power adapter cable" to the "
+
" pole of the product, and the
"black
wire"
to the "
-
" pole of the product; connect the "12V/1A adapter power supply" to the "power adapter cable" .
Figure 2-2 Connecting the antenna and power
(2) Notes:
a. When wiring, please do not connect the wrong port, so as not to damage the product! !
b. For the RF antennas of the transmission pair, it is necessary to be as open as possible and to be able to see directly; the
RF antennas should be as far away as possible: walls, metal shields, big trees, hills, large buildings, etc.
c. The top of the radio frequency antenna should not be attached to objects that have a great attenuation effect on radio
frequency, such as metal and walls, so as not to affect the transmission of radio frequency signals.
d. The distance between the RF antennas of the product is preferably 1 meter or more. If the high-power RF product is
too close to the RF antenna, the receiver cannot receive data. (For more details, see the Frequently Asked Questions and
Solutions (FAQ) section)
2.2.2 Step 2: Sending (collecting) terminal product signal input wiring
(1) Connect a switch (or sensor, etc.) to the DI and GND interfaces of the K61-40 acquisition end of this product as
shown in Figure 2-3 below. Then, after tightening the screw on the plug-in terminal of this product, close the switch (or
let the sensor output a closed switch signal). When the switch is closed, the corresponding IO light is always on,
indicating that the switch closed signal is collected.
(2)
Notes:
a. When the input voltage is applied, below 0.7V belongs to the closed state (effective state and the switch signal is
closed), and above 0.7V belongs to the open state (invalid state and the switch signal is disconnected).
b. When the communication between the K61-40 device and the K61-04 device is successfully established, the "NET"
light is on;
c. When the switch signal is collected, the corresponding IO light is always on. If the IO light is not on, please check
whether the sensor outputs a closed switch signal normally;
d. When the terminal is connected to the wire, please tighten the screw on the plug-in terminal of this product, and pay
attention that the conductive part of the terminal cannot be pressed against the insulation layer of the wire, so as to avoid
