Focuser Overview

The Optec FocusLynx driver is used for all three of the Optec Lynx family focuser types. All models support a base set of features but they do differ. This tutorial is mean to go over the basic physical features of each model.

All Lynx family focusers support serial connections. All have an LED that is turned on by the controller once it finishes booting.

FocusLynx Controller

The Optec FocusLynx controller is the primary external controller for most Optec Focusers. It supports up to two focusers via the dual output. It uses a 2.5 x 5.5 mm power jack to receive 12 volt input power.

The FocusLynx controller supports connections via Serial, Ethernet, Hand Controller, and WiFi (using the optional WiFi add in card). As many modern computers do not have hardware Serial ports the FocusLynx is designed to work with the Optec USB to Serial cable.

The FocusLynx controller also supports connections via networking. Both the Wired Ethernet and the optional WiFi support DHCP and Static IP networking. Generally for permanent installations Wired networking is recommended.

Note

The FocusLynx package comes standard with a single focuser control board. However, the system is capable of controlling two focusers with the optional secondary stepper board. Contact Optec or your dealer for pricing information.

TCF-LSI

The TCF-LSI is an all in one focuser. It uses an embedded version of the FocusLynx controller allowing it to operate without an external controller. The embedded controller supports Serial connections only. It uses a 2.5 x 5.5 mm power jack to receive 12 volt input power. The final port supports external temperature probes and the Optec In Out keypad.

ThirdLynx X-Series

The Optec ThirdLynx focusers are all in one focusers. They use an ebedded controller, allowing them to operate without any external controllers. The X-Series focusers connect to the computer via USB CDC, allowing them to use the same Serial command protocol as the FocusLynx. They use a 2.5 x 5.5 mm power jack to receive 12 volt input power. On recent versions the LED will blink if there is no 12 volt power available to run the motor.
