Improvements Over Servo Controller I
- 4 extremely high-speed encoder inputs
- Industrial terminal blocks
- Double the motor amperage
- Built-in autoguider port
- USB and RS-232
- Better custom enclosure
- Overtravel limit switch inputs
- PEC limit switch inputs
- Homing switch inputs
- 4× more memory
- 4× the clock speed
- LEDs for handpad & comm status
- Cascade telescope encoder mode
All features of the original Servo Controller I are included. All existing SiTechExe and ScopeII software works with the Servo II.
Cascade Encoder Mode: Requires high-resolution encoders (~13 million ticks/rev, available from Renishaw and others). The servo motors are driven until there is zero positional error on the telescope axis hi-res encoders — enabling mount models in the low arc-second range and long-exposure unguided imaging with SiTechExe (PointXP by Dave Rowe).
