Direct Serial Control

Section 2.3 - Operating Focusers With Direct Serial Commands

The following instructions assume that you are using the Optec Terminal Application, available from the Optec website. If you are using another serial terminal application, the interface and commands should be very similar.

After opening a connection to the focuser hub, you should be able to send serial commands to the FocusLynx using the following instructions:

• Plug In Your Focuser - Ensure that there is a valid connection between your focuser and one of the two focuser ports on the FocusLynx.

• Enter A Command - Enter the command into the Transmit Data text box.

• Send The Command - When your command is finished, click the Send button or press the Enter key to send the command.

Note: It is possible to send more than one command simultaneously! Just enter each command into the Transmit Data text box as you would a single command, and when you send them off, they will be executed in the order they were written.

• Check The Response - Within moments, a response (if any) will appear in the Received Data text box.

• Clearing Responses - To clear old responses out of your received data log, click the Clear button.

Note:  With both relative and absolute moves, if you try to move beyond the physical limits of the focuser the focuser hub firmware will stop you from doing so to prevent you from damaging the focuser. This is why it is extremely important to ensure that you have configured your focuser type!
