Revised August 2017 These instructions are written by two users on RCGroups: jj604 and Daedalus66 . We are not associated with Lemon RX. LemonRX and OrangeRX are brand names. Spektrum, DSM2, DSMX, X-BUS, Airware, STi, and the Telemetry logo are Trade Marks of Horizon Hobby. These names are used here simply as descriptions of those items.

DSMX vs DSM2 – and Lemon's own DSMP Most Lemon receivers are fully DSMX-compatible and backward compatible to DSM2 . The “Feather Light” series and some of the other older receivers are only DSM2-compatible. The DSMX protocol developed by Spektrum includes frequency hopping for more reliable operation in areas of high potential interference from other 2.4GHz transmitters, but receivers using the older DSM2 protocol, also by Spektrum, continue to work well in all but the most demanding conditions. Lemon “DSMX-compatible” receivers work with any DSMX-compatible transmitter and are backward compatible with older DSM2-type transmitters. Lemon “DSM2-compatible” receivers work with either a DSM2-compatible transmitter or a DSMX-compatible transmitter operating in DSM2 mode. Revised August 2017 Most recent Spektrum DSMX transmitters support both modes and will automatically detect a DSM2 receiver at bind time. The exceptions are transmitters sold in the EU since 2015and the DXe, which support only DSMX.1 DSM2 in the EU. A significant change of regulations in the European Union requires that transmitters sold there after January 1, 2015 NOT include DSM2 modulation. Consequently, DSMX transmitters now sold in the EU support only DSMX-type receivers. Transmitters sold before 2015 that include DSM2 capability continue to be fully legal for use. Spektrum DXe. The low-costSpektrum DXe transmitter supports only DSMX, wherever it is sold in the world. Other currentSpektrum transmitters continue to support both DSMX and DSM2, except in the EU. Lemon “DSMP” receivers work with either a DSM2-compatible transmitter or a DSMX-compatible transmitter. DSMP is Lemon’s proprietary protocol that includes DSM2 and DSMX compatibility but adds some additional features. 2 . Binding Binding is the process

FAQs

Lemon RX 接收机如何判断 DSMX 与 DSM2 的兼容性？

Most Lemon receivers are fully DSMX-compatible and backward compatible to DSM2。Feather Light 以及部分较老接收机仅兼容 DSM2。DSMX-compatible 接收机可用于任意兼容 DSMX 的发射机，并向后兼容 DSM2 传输。

为什么绑定时需要控制发射机与接收机距离？

Binding 需要将接收机“锁定”到对应发射机。说明文档要求发射机与接收机分开约 3-6ft/1-2m，避免发射机“swamp”接收机；必要时可能需要更大分离（如 10ft/3m）以完成绑定。

进入绑定模式后接收机 LED 应该如何表现？

接收机红色 LED 会快速闪烁以指示绑定模式。如果 LED 不按预期快速闪烁，可能存在问题（例如电源连接反接），应确认快速闪烁后再继续操作。
