1. Overview & Purpose

️· Product: CUI Devices AMT11 series modular incremental encoder.
️· Function: Measures rotational position/speed.
️· Key Feature: Modular design enabling customization and assembly. It uses tools (A, C) for proper alignment and installation.
️· Communication: Supports a serial UART interface for configuration, diagnostics, and position zeroing.

2. Mechanical Assembly & Features

️· Assembly Steps: Detailed instructions provided using tools A and C for precise alignment. This includes defining distance, sliding components over the shaft, pressing adapters, and securing the top cover. Recommends limiting top cover removal cycles.
️· Bases: Two base options:
- Standard Base: Typical mounting pattern.
- Wide Base: Provides more mounting options. Outer mounting holes are oblong.
️· Tools:
- Tool A: Spacer for initial alignment and distance.
- Tool C: Centering tool; used for pressing components and final alignment.

3. Serial Interface & Programming

️· Interface: Serial UART (115200 baud, 8 data bits, no parity, 1 stop bit, 1 start bit).
️· Commands:
- `0` (Hex 0x30): Zeros the encoder, storing the index position.
- `Q` (Hex 0x51): Resets the encoder (like a power cycle).
️· Pins:
- TX\_ENC+: Encoder transmit.
- RX\_ENC+: Encoder receive.
- MCLRB: Used for reprogramming.

4. Important Notes & Specifications

️· Limited Warranty: One year.
️· Modifications: CUI Devices can change products without notice.
️· No Critical Applications: Not designed for life-support devices.
️· Resolutions: 360 and 2500 PPR options.
️· Operating Temperature: Up to 125°C
