Updated design - longer option (5m), more flexible cable!

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.

Skywatcher Az gti USB cable
Monday, 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.
Wednesday, 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.

Lynx Astro FTDI EQDIR USB Adapter for Sky-Watcher AZ, GTi Mounts
Wednesday, 17 November 2021  | 

Bought this Adapter on advice from a friend who has the same equipment as me and has experienced the same wi-fi problems. So acting on their advice bought this from FLO and am reasonably happy with both the product and to a lesser extent the lack of notification and delivery time.
Nevertheless the adapter seems to resolve the wi-fi stability and Iím now able to slew my scope so as to use the SynScan program.

Second EQDIR Cable
Wednesday, 29 September 2021  | 

I already had a Lynx Astro EQDIR cable for my NEQ6, but bought this one to use with an AZ-GTi mount and the new dual AZ-EQ firmware. Being familiar with the whole setup, I expected this cable to work flawlessly, which in the end it did but not after a few issues unrelated to the cable. I was seeing erratic mount behaviour and disconnections/stalling which basically boiled down to communications errors between the laptop and the mount . After trying all sorts of things, different computers, different comms settings, re-installing EQMOD and ASCOM, etc. nothing worked.

Eventually I tried running the AZ-GTi on batteries and everything worked fine. I think the power supply (which had previously worked fine with the NEQ6) was causing interference. It might be that the power supply was getting old, or that the AZ-GTi is more susceptible to interference. I bought a replacement power supply from FLO and everything is not working great. Can't fault FLO's customer service as they worked to try and resolve my problem so thanks!

Great cable
Tuesday, 6 July 2021  | 

I bought this cable to connect my laptop to my AzGti mount as I usually do this wirelessly but wanted a wired connection for my peace of mind whilst guiding, not used it in anger yet due to clouds but tested it indoors and does what it says on the tin, a great quality reliable cable

Perfect for connecting AZGTi (EQ mode) to ASIAIR PRO
Sunday, 4 April 2021  | 

I placed this order on FLO on a Sunday evening (from California) and it was delivered by DHL on Thursday afternoon! This cable works great for connecting my AZGTi (in EQ mode) to my ASIAIR PRO and it is so much easier than trying to connect wirelessly. It also allows me to run ASIAIR PRO in 5GHz instead of the 2.4 GHz limit with wireless.

GREAT service from FLO and DHL

Quick delivery but cable didnít work for me.
Saturday, 13 February 2021  | 

Excellent service as usual from FLO. Ordered the cable yesterday and it arrived today.

I bought this cable to try and update my AZGTi as itís stuck in firmware mode and a review on here suggested the cable worked for them with their AZGTi.
I had to download drivers even though laptop is WIN 10. In Device manager the cable is displayed and says is connected and working. However when I connect it direct to the AZGTi mount, it stil wonít update firmware and either fails after a small percentage or says cannot connect to motor controller. It detects the correct COM port but having spent two hours trying to update, Iíve given up trying. The AZGTi will now have to be consigned to the bin. Very disappointed in Skywatcher products as this is the second item that has failed within last two weeks (other was my EQ3-2 synscan which appears to be the motherboard.

Skywatcher firmware updates seem to not like new technology e.g.USB. 3 and WIndows 10. And their WiFi products are very flaky (my synscan dongle constantly fails to be detected by the synscan app). For a company that charges a premium for its products, their support is non existent (Skywatcher not FLO I hasten to add).

Very frustrated at the time, effort and money Iíve wasted!

Iím sure the cable works as designed so feel free to purchase but not to use for updating firmware.
