4. Setup
- Unpacking: Carefully remove the SHC Smart Hand Controller V2 and all accessories from its packaging.
- Connecting to Mount:
- Locate the RJ11 Control/ONSTEP Port on the bottom of the SHC controller.
- Connect one end of the provided RJ11 cable to this port.
- Connect the other end of the RJ11 cable to the corresponding ONSTEP control box port on your astronomical mount.
- Important: Do not connect the USB Upgrade Port and the RJ11 Control Port simultaneously during normal operation.
- Powering On: The controller typically draws power from the Onstep control box once connected. The OLED display should illuminate.
- Initial Check: Verify that the display shows relevant information (RA, Dec, tracking speed) and that the directional buttons respond to input.
5. Operating Instructions
- Power On/Off: The controller powers on automatically when connected to a powered Onstep control box. To power off, disconnect from the control box.
- Navigation and Movement:
- Use the Directional Pad (N, E, S, W) to move the telescope mount in the respective directions.
- The Center Button within the directional pad typically acts as a selection or confirmation button.
- Speed Control: The display shows the current tracking or slewing speed (e.g., "20x 1/2x"). Speed adjustments are usually made through the F1/F2 buttons or menu options.
- Auxiliary LED: Press the LED button (red button) to activate or deactivate the auxiliary light. This is useful for low-light conditions.
- Function Buttons (F1, F2): These buttons are typically programmable or context-sensitive. Refer to your Onstep mount's specific firmware documentation for their exact functions (e.g., changing speed, accessing menus, GOTO commands).
- Firmware Upgrade:
- Disconnect the RJ11 control cable from the controller.
- Connect the USB Upgrade Cable to the USB port on the bottom of the controller and to your computer.
- Follow the instructions provided by Terrans Industry or the Onstep open-source community for firmware upgrade procedures.
