Product OverviewThe Astro Devices RJ11 Encoder Adapter Cable connects an encoder to a digital setting circle (DSC) through a standard encoder cable. One end carries a 5-pin flat polarised connector that mates with US Digital's S1/S2/S5/S6 encoders and CUI's AMT102, while the other end terminates in an RJ11 (6P4C) jack. The assembly is 150 mm (6") long and weighs 30 g, giving you a short, tidy bridge between the encoder and the rest of an RJ11-based encoder harness.Who It's ForThis cable suits push-to telescope and Dobsonian owners running a Nexus DSC or another digital setting circle system that uses RJ11 encoder cabling. It is the right adapter when your encoder uses the flat 5-pin polarised header (US Digital S1/S2/S5/S6 or CUI AMT102) and your DSC harness expects an RJ11 (6P4C) plug.Key Features & Design Dual-standard termination: a 5-pin flat polarised connector on one end and an RJ11 (6P4C) jack on the other. Encoder compatibility: works with US Digital S1/S2/S5/S6 and CUI AMT102 encoders. Compact length: 150 mm (6") keeps the run short and manageable between the encoder and the encoder cable. Light and unobtrusive: 30 g adds negligible weight to a mount. Recommended UsesUse this adapter to bring a US Digital or CUI encoder into an RJ11-based DSC wiring setup, whether you are adding encoders to a Dobsonian, wiring a new push-to build, or replacing an adapter in an existing Nexus DSC installation.Compatibility and Accessory NotesThe 5-pin flat polarised end fits US Digital S1, S2, S5 and S6 encoders and the CUI AMT102. The RJ11 (6P4C) end connects to a DSC or encoder cable that accepts an RJ11 plug. Confirm that your encoder cable and DSC port use the RJ11 (6P4C) standard before ordering.Good to Know Before You OrderLength: the adapter is 150 mm (6") long, intended as a short jumper rather than a full-length encoder run.Connector match: the flat 5-pin end is polarised, so it seats in one orientation to keep the encoder wiring correct.What's in the box: one adapter encoder cable.Frequently Asked QuestionsWhich encoders does this adapter work with?It mates with US Digital's S1/S2/S5/S6 encoders and CUI's AMT102 through the 5-pin flat polarised connector.What connects to the RJ11 end?The RJ11 (6P4C) jack connects to a DSC or encoder cable that uses an RJ11 plug.How long is the cable?It measures 150 mm (6") end to end.Is it difficult to set up?No. Each end uses a keyed connector, so the flat 5-pin plug meets the encoder and the RJ11 jack meets the encoder cable, and the polarised header seats in a single orientation.Bottom LineThe Astro Devices RJ11 Encoder Adapter Cable is a compact 150 mm bridge that brings US Digital and CUI encoders into an RJ11-based DSC setup, with keyed connectors on both ends for a straightforward, correctly-oriented connection.
