TouchDRO Scale Compatibility
Quick reference for determining if your DRO scale will work with TouchDRO adapters. Use this section to quickly answer "Will TouchDRO read this scale?" without diving into detailed documentation.
Compatibility Overview
✅ Fully Compatible
- Chinese glass scales (Ditron, Easson, generic)
- Heidenhain incremental scales
- Mitutoyo AT2xx series (quadrature)
- iGaging and Shahe digital calipers
- Most magnetic scales with quadrature output
⚠️ Compatible with TDA-4xx Only
- Heidenhain analog scales (sin/cos)
- Mitutoyo AT1xx series (analog)
- Mitutoyo Digimatic protocol
- Renishaw TONiC analog scales
- High-end Magnescale analog scales
❌ Limited or No Support
- Mitutoyo AT7xx series (proprietary digital)
- Renishaw BiSS protocol scales
- Heidenhain EnDat protocol scales
- Proprietary machine tool scales
- Scales requiring >5V power supply
Quick Compatibility Check
Step 1: Identify Your Scale Type
- Look for brand markings: Manufacturer name and model number
- Count connector pins: 4-pin (usually SPC), 9-pin (usually quadrature), 15-pin (usually analog)
- Check power requirements: Most compatible scales use 5V
Step 2: Check Signal Type
- Digital quadrature (A/B phases): ✅ Fully compatible
- Analog sin/cos: ⚠️ TDA-4xx only
- SPC/Digimatic serial: ✅ Compatible (varies by adapter)
- Proprietary digital: ❌ Limited support
Step 3: Verify Adapter Compatibility
- TDA-4xx series: Supports all compatible signal types
- DIY glass scale kits: Quadrature signals only
- DIY iGaging/Shahe kits: SPC protocols only
