Do multiple wireless lever kits on the same site affect each other?
No. During pairing, each joystick establishes a session only with its own servo motor, and communication runs over the AXI-specific encrypted XRF protocol. On the HCT402, pairing must be performed within 50 meters. Thanks to this pairing, another remote control working on the same site is prevented from commanding your motor.
On sites with multiple pieces of equipment there are two separate risks: mismatched pairing (another remote control driving your machine) and interference (command loss due to a crowded band).
Mismatched pairing is prevented by the session-based encrypted protocol. The joystick does not command any device other than the motor it is paired with.
On the interference side, the 2.4 GHz band is shared; frequency hopping operation gets past occupied channels. Still, field practices matter:
- Label each kit to its own equipment so there is no room for confusion. Two joysticks of the same model look physically alike.
- Keep unused remote controls in the charging station; the HCT402 does not accept commands while charging, which reduces the risk of accidental commands.
- Make the division of work between operators clear; technical measures do not cover organizational error.
If any kit loses its link, the others are unaffected; the disconnected system moves the motor to the safe center position within 250 ms and stops the oil flow of that lever.
