KAPPA Telemetry Receiver Module
DS-KAPPA-T868-2
KAPPA-T868 Operation
1.
Operation
The KAPPA module will remain in a low power listening mode at all times when power is
present.
When a valid packet is received it will wake and action any output state changes required.
2.
Moment are or Latching Function
KAPPA actions button state change only, therefore momentary mode requires receipt of a
“button down/input active” packet and a “button up/input not active” packet from a
transmitter. In momentary mode on receiving a “button down” the KAPPA will hold its output
active until a “button up” is received. In latching mode KAPPA must see “button down” then
“button up” in order to make a state change to either activate or deactivate an output.
3. Pairing
Using Pin 8 it is possible to “pair” transmitters into the receiver memory as follows:
1.
Briefly GND Pin 8, the LED will flash once - this shows OP1 is selected
2.
GND Pin 8 again after release the LED will flash twice to show OP2 is selected
3.
Repeat above process to select OP3 or 4
4.
With the desired output selected (and before a 10sec timeout)
5.
Press the button or activate the input on the transmitter to be paired.
6.
This will complete the pairing and the LED will flash twice to confirm
Memory: maximum storage is 70 pairings.
4. Erase
To erase the KAPPA memory and remove all stored transmitter input pairings press and hold
the learn button for 10 seconds.
The LED will illuminate while the button is held and after release will flash 3 times to confirm
memory erase is complete.
Above assumes LED connection as per schematic example on Page 5
5. Outputs
Outputs are LVTTL / LVCMOS at Vcc and are Active high.
