WK2x01

Details

Protocol Number: 30 Autobind: Yes Channel Re-mapping: Yes Extended Limits: Yes Failsafe Support: Yes - WK2801 sub-protocol Receiver Match: Yes Telemetry: No Option Value: N/A

Notes

Sub-protocol choice roughly corresponds to the number of channels supported by the receiver, but many of the newer 6-channel receivers actually support the WK2801 protocol.

It is recommended to try the WK2801 sub-protocol first when working with older Walkera models, before attempting the WK2601 or WK2401 mode, as the WK2801 is a superior protocol.

The WK2801 protocol supports up to 8 channels.

Sub Protocols

0 - WK2801

CH1	CH2	CH3	CH4	CH5	CH6	CH7	CH8
A	E	T	R	CH5	CH6	CH7	CH8

Serial Mode Binding

• With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.

• Turn on the TX, set protocol = WK2X01, sub_protocol = WK2801 with option=0, turn off the TX (TX is now in autobind mode).

• Turn on RX (RX LED fast blink).

• Turn on TX (RX LED solid, TX LED fast blink).

• Wait for bind on the TX to complete (TX LED solid).

• Make sure to set a uniq RX_Num value for model match.

• Change option to 1 to use the global ID.

• Do not touch option/RX_Num anymore.

PPM Mode Binding

• With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.

• Turn on RX (RX LED fast blink).

• Turn the dial to the model number running protocol protocol WK2X01 and sub_protocol WK2801 on the module.

• Press the bind button and turn on the TX. TX is now in autobind mode.

• Release bind button after 1 second: RX LED solid, TX LED fast blink.

• Wait for bind on the TX to complete (TX LED solid).

• Press the bind button for 1 second. TX/RX is now in fixed ID mode.

• To verify that the TX is in fixed mode: power cycle the TX, the module LED should be solid ON (no blink).

• Note: Autobind/fixed ID mode is linked to the RX_Num number. Which means that you can have multiple dial numbers set to the same protocol with different RX_Num and have different bind modes at the same time. It enables PPM users to get model match.

1 - WK2401

Models: WK2401 is used with older Walkera models.

CH1	CH2	CH3	CH4
A	E	T	R

2 - W6_5_1

Models: WK2601 - 5+1

CH1	CH2	CH3	CH4	CH5	CH6	CH7
A	E	T	R	Gear	Disabled	Gyro

• Aileron, Elevator, Throttle, Rudder, and Gyro (CH7) are proportional

• Gear (CH5) is binary

• CH6 is disabled

3 - W6_6_1

Models: WK2601 6+1

This mode is highly experimental!

CH1	CH2	CH3	CH4	CH5	CH6	CH7
A	E	T	R	Geal	Collective	Gyro

• Aileron, Elevator, Throttle, Rudder, Collective (CH6), and Gyro (CH7) are proportional

• Gear (CH5) is binary

4 - W6_HEL

Models: WK2601 Heli

CH1	CH2	CH3	CH4	CH5	CH6	CH7
A	E	T	R	Gear	Collective	Gyro

• Aileron, Elevator, Throttle, Rudder, and Gyro (CH7) are proportional

• Gear (CH5) is binary

• Collective (CH6) is linked to Throttle

  • If CH6 >= 0 the receiver will apply a 3D curve to the Throttle

  • If Ch6 < 0, the receiver will apply normal curves to the Throttle

  • The value of CH6 defines the ratio of Collective to Throttle

• Option Value = maximum range of Collective servo

5 - W6HEL_I

Same as W6_HEL, but with Collective inverted.
