FTDI EQDIR USB Adapter for Sky-Watcher AZ-GTi Mounts

Important: EQMOD only works with mounts in equatorial mode, you may need to install the new EQ mode firmware for your AZ-GTi prior to use.

This convenient FTDI EQDIR adapter allows direct connection of a Sky-Watcher AZ-GTi Mount to your laptop. 

The FTDI 232R chipset works reliably across all versions of Windows and, because each cable has a unique chipset ID, each time you unplug the adapter then plug it back into the same computer, even if on a different physical USB port, the COM port number remains the same.

And, we quality control each and every Lynx Astro cable prior to dispatch. 

1, 2 or 5m cable length.  

Compatible with Windows XP, 7, 8 & 10, Linux, Mac OSX 10.3 and above.

Windows users, the EQDIR adapter should install automatically but should you require drivers they can be downloaded here.

The EQMOD project consists of a suite of open source applications that bypasses the hand-controller and communicates directly with the mount's stepper motor controller.

Poor USB Cable by Gary Warnes
07 October 2023  | 

Being having a lit of connection issues with this cable to my laptop with the Skywatcher SynScan windows app easily losing the connection to the GoTo tripod. Just touching the USB end of the cable with a single nudge with a finger disconnects the app even when attached to a USB Hub. Hopefully duct taping the cable to the hub and the wire to the table will fix the issue. Not sure if there is another make of cable I can buy which won't have this terrible issue.


It sounds like there is a fault with this cable, please get in touch and we will arrange to collect and replace. We check every faulty Lynx Astro cable in our workshop because we see so few issues given the amount of QC testing we do on these that we like to understand any faults. It sounds like in this instance cable snag has caused damage to the USB connector.

Lynx EQ Cable - WiFi woes solved
21 April 2023  | 

Appears to be reasonable quality cable. For the price I would have liked a bit more protection around the connectors. Hence the 4 stars.

I did put some heat shrink over the phone connector end that attaches to the mount just to add some extra support, as this looked like a weak spot.

Most importantly this instantly solved all my WiFi woes. Gone are the super frustrating drop outs and re-alignments. Im running guiding from my laptop using PHD, and the cable link has improved the performance and reliability. Didnt connect to my Az-Gti straight away. I had to increase the connection timeout. Once that had been done its worked flawlessly.

Normal brilliant support and delivery service from FLO

No need now to fiddle around with wifi settings when the AZ-GTi decides to reset the wifi settings. One less thing to worry about. Great item.

Skywatcher Az gti USB cable
20 June 2022  | 

Required a good well made cable for comms from pc to mount, some of these are cheap and not well made and can cause damage to equipment, finding this cable with FLO being a good supplier I was confident they had sourced a good product, indeed it is well made with glued heat shrink down to the RJ connector, quality USB dongle fitted with choice of cable lengths.. Happy to pay a little extra for peace of mind..

Works but needed modification.
30 March 2022  | 

Although the cable works the plastic strain relief on the rj12 end needed trimming in order for it to fit into the socket of the AZ GTI.Once cut back with a very sharp craft Knife it fitted. Quality control from Lynx needs to check if the item fits.


Sorry about this - we recently started adding some additional strain relief to these but need to tweak the length slightly to ensure it suits all sockets. This has already been fixed in our production department ongoing.
