About this product

Model:  lynxastro_eqdir_sw_rj45_2m
Part Number:  FES-ASS-FTDI_5V-TTL_RJ45_2M

Updated design with a longer (up to 5m), more flexible cable!

FTDI EQDIR USB Adapter for Sky-Watcher EQ3 PRO, EQ5 PRO, AL55i Mount, HEQ5 Syntrek & PRO, EQM-35 PRO, AZ EQ5-GT, EQ6-R PRO, AZ EQ6-GT and EQ8 Mounts,Star Adventurer GTi Mount.

Also suitable for use with the Orion Sirius EQ-G. 

This convenient FTDI EQDIR adapter allows direct connection of Sky-Watcher EQ3 PRO, EQ5 PRO, HEQ5 Syntrek & PRO, EQM-35 PRO, AZ EQ5-GT, AZ EQ6-GT and EQ8 Mounts 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.

We have also taken this opportunity to specify a higher quality RJ45 plug with a rubber cowl that prevents snagging and an integral 'boot' (a reinforcing sleeve) for extra strength. 

And, we quality control every Lynx Astro cable before 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 comprises a suite of open-source applications that bypass the hand controller and communicate directly with the mount's stepper motor controller.

NOTE: The Skywatcher EQ5 PRO, HEQ5 PRO/Syntrek, EQM-35 PRO, AZ EQ5-GT, EQ6-R PRO, AZ EQ6-GT and EQ8 mounts all use the same Lynx Astro FTDI EQDIR adapter, so if you upgrade from one to another you will not need an additional EQDIR adapter.

Great quality cable
18 April 2024  | 

Not the cheapest cable, but it is well made and feels like it will last a long time, the ends are nicely secured and the cable is reasonably flexible, no problems in use, reconised straight away on my Raspberry Pi and connected to the motor control board of my Synscan EQ5 Pro mount in place of the hand controller, was then able to control the mount with the EQMOD driver.

Quality cable
18 November 2023  | 

This replaced a budget cable that was no longer working. The plugs in the new cable are a snug fit and the ASIair connected immediately to the mount without issue. Problem solved. Cable appears well made and will hopefully give many years of reliability. Expensive but highly recommended.

Pc cable for AZEQ6
08 September 2023  | 

Bought this as an upgrade to my basic eq-direct cable.
Very nice heavy duty type, a bit pricey for a cable (over £40) but I cannot fault its build quality or looks.
Great service from FLO as usual!

Worked flawlessly with ASIAIR Plus and HEQ5Pro mount

Worked first time syncing the Plus and my mount. Expensive for a cable but hey, it worked with no hassle

Very Happy with my cable
24 March 2023  | 

Am very happy with my cable I recently purchased from FLO, I brought to enable me to connect my new scope with my laptop. It took awhile but with advice from flo, I was able to successfully do it. And the cable is performing as it I hoped it would. Will definitely be doing business with again.

Did not work for me. Maybe a bad sample.
18 February 2023  | 

Disappointed by this relatively expensive cable. After many frustrating hours of trying to use this with EQMOD, I was reduced to second-guessing, and ordering a far cheaper FTDI cable from Amazon UK for my Sky-Watcher AZ-EQ6 GT Pro mount. That worked instantly.


We are surprised and confused.
We can find no communication from you requesting support.
If you had contacted us, we would have recommended you install the windows drivers, if windows hasn't done so, and select the correct com port in EQMOD.
Every single cable is tested in-house before dispatch. We have sold thousands over the years and have not experienced a single failure like the one you describe.
Please do contact us. We like to help and want to learn.

Lynx Astro FTDI EQDDIR USB Cable
19 January 2023  | 

A very high quality, technically superior piece of equipment which can withstand freezing temperatures without disintegration. Thoroughly recommended.

Bought this to connect my ASIAIR PLus to my EQM-35 Pro and it works brilliantly. Plugs into the mounts control box in place of the handset cable, so no more handset! Much easier.

Donít bother with cheeper alternativesÖ
23 November 2022  | 

Bought this cable after trying 3 cheeper alternatives from Amazon that all failed to connect my asiair to my heq5 mount without piggybacking my controller. This worked perfect first time. Itís not cheep for a cable but in terms of removal of setup stress this was a great buy.
