There are multiple encoder options that can be used with ETC Rigging 3rd Party Controls.
Fixed Speed Motor Starter (FSMS):
- TTL Encoder (Differential Signal)
- 5-30 VDC Supply
- 5V Signal
- HTL Encoder (Differential Signal)
- 5-30 VDC Supply
- Requires HTL -> TTL Conversion Card
- Quadrature Encoder (Single Ended Signal)
- 10k Analog Pot
Variable Speed Motor Starter (VSMS):
- TTL Encoder (Differential Signal)
- 5-30 VDC Supply
- 5V Signal
- HTL (Differential Signal)
- 5-30 VDC Supply
- Requires HTL -> TTL Conversion Card
- 10k Analog Pot
- For use with SoftLift Fixed Speed Control Only, not reccommended.
Motor Control Interface (MCI):
- TTL Encoder (Differential Signal)
- 5-30 VDC Supply
- 5V Signal
- HTL (Differential Signal)
- 5-30 VDC Supply
- Requires HTL -> TTL Conversion Card
- 10k Analog Pot
ETC recommends using Belden 9728 or equivalent for encoder field wiring.
