Adapter and Scale FAQ

‣ Do you sell complete DRO kits with scales and display?

No, we sell only the adapter units. You will need to source a set  of compatible DRO scales and an Android tablet that meets TouchDRO system requirements.

‣ Which scales and/or touch probe should I get for my machine?

Please see the Recommended Scales and Touch Probes

‣ Will TouchDRO Adapter work with my DRO Scales?

TouchDRO supports the majority of modern TTL and RS-422 DRO scales. Please refer to the Supported Optical and Magnetic DRO Scales page for more information.

‣ Can I use rotary encoders with TouchDRO?

Yes. TouchDRO can work with TTL and RS-422 encoders with 5V NPN or Push/Pull output. 

‣ Can I mix scale types or resolutions with TouchDRO?

Yes. You can mix glass and magnetic scales, RS-422 and TTL scales, and scale resolutions. 

‣ Will TTL scales or scales without a reference track work with TouchDRO?

Yes. The RS-422 input drivers used by the TouchDRO adapters can gracefully handle TTL inputs. 

‣ What is the difference between TouchDRO TDA and TDK adapters.

TDK adapters are sold as partially assembled kits, while TDA adapters are sold as fully assembled units and offer additional features. Please see the Adapter Comparison page for a detailed list of differences and feature explanation. 

 ‣ Can I add tachometer or touch probe inputs myself to an adapter that doesn't come with them?

No. The adapters that have touch probe and tachometer support use a different firmware.
