Yes, it is available for sale at this right moment, DOT (Door Operator Translator).
The actual model is for DMC1, and pretty soon there will be a version for the TAC20-3.
Call Hytec 800.883.1001 and ask about the DOT unit, the operator will transfer you to the customer service rep. They are upgrading the website about the DOT.

Dowtiedrooster16, what do you want to know about this unit?

It is a metallic box smaller than 6x4x2", with 2 communication wires you connect to the DMC1, it has 10 wires cable you connect to the MOVFR2, uses 24V power from the MOVFR2 curtain connector, an internal jumper to select front/rear door, and that's it. The DMC1 sees it as an old door operator FX board, and DOT will control the door through the MOVFR2 open/close/nudge inputs and reads the DPM/DOL/DCL/Reopen MOVFR2 outputs. It translates the operation between DMC1 and the MOVFR2 operator. The DOT is installed over the MOVFR2 aluminum plate. The old door-gate-switch still connected directly to the DMC1 relay board. There are 5 LEDs on top, two to indicate communication, the other three for Open, Close, Nudge as commands received from DMC1. Having rear door, two MOVFR2 and two DOTs (the rear with the jumper) will do the job. No more blow up expensive FX boards, motor, encoder.

We installed one on the DMC also. It does not have to be a GAL, it will interface with any door operator.

Looking forward to the tac 20-03 ourselves.

You're really better of using either the Wittur drive only or the retrofit version of the GAL MONXT called omni. This will allow you to retain the Miami Elevator/early TK door hardware including the clutch, which is still in spare production.

You can retain the old door locks and pick up rollers 3 ways. You can just use the movfr with the direct drive mount and add the ramp for the clutch to the movfr set up. I've done several that way on other dovers. Second way is there a guy who created a setup that allows you to keep the dover pickup rollers and door locks while using a gal clutch by switching where the rod attaches on the keeper with some custom little parts. And the third way, is a part I make, that you add to the gal clutch to work with the existing hardware.

I'm no fan of harmonic door operators. I don't know why anyone in their right mind would install one on a completely new job. I can understand the constraints on mods though. The european linear ones with the cabin door lock are my favorite. No gate switch that pranksters and enthusiast can tinker with.
