Optec WiFi Wireless Option

New!  Replaces FocusLynx WiFi option - #19535

#19755 - OptecWiFi 802.11b/g Wireless Network Option

Designed for FocusLynx and Gemini control circuits

FocusLynx WiFi OptionThe FocusLynx and Gemini Control Hubs include a wired Ethernet connection and interface as standard.  However, many users prefer to use wireless Ethernet with their telescope setups.  The Optec WiFi wireless networking option eliminates the need for any communication wires to the control PC or tablet.  Taking advantage of the 802.11b/g  networking standard, the Optec WiFi option allows true wireless networking connectivity. 


With the WiFi Option in place, an Ad-Hoc network is created by the wireless module that allows easy communication and integration into any existing 802.11b/g wireless network.  Control of the FocusLynx hub can be accomplished through Optec's iPhone or Android OS apps using the built-in wireless web pages allowing the user to focus through most any smartphone.  Concurrent communications ensure FocusLynx or Gemini Commander software, ASCOM client software, connected hand controllers, and smartphone are all updated simultaneously. 

The #19755 FocusLynx WiFi Option can be added to any existing FocusLynx or Gemini system at any time.  Contact Optec Technical Support with questions or for assistance with your configuration.

SoftAP Installation:

Windows 10 does not enable support for Ad-Hoc networks by default, so the Optec WiFi can be configured using the SoftAP interface.  With SoftAP, the Optec WiFi board creates a temporary net using a simplified DHCP server.  To configure, you wil first attach your PC or mobile device to this network, attach the Optec WiFi board to your WPA-PSK or WPS2-PSK wireless network, then re-attach to your local wireless network and re-establish your connection to the hub. 

The Optec WiFi can be set for a static IP address as well as act as a DHCP client.  Use of a dedicated home wireless router and DHCP server is highly recommended.
