Teradek RT MDR.S Motor Driver

Teradek RT MDR.S is a tiny receiver+control unit to drive lens motors. I guess the “S” in MDR.S could stand for small or stylish.

You can control a single motor or daisy-chain up to 3 motors—for focus, iris and zoom. Short cables minimize clutter.

MDR.S connected to RT MK3.1 Brushless Lens Motor. The motor comes with thin, flexible cables and gears are available in 0.8, 0.6, 0.5, and 0.4 width.

MDR.S works with Teradek’s CTRL.1 single channel or the CRTL.3 three channel hand unit.

Teradek RT Single Channel Kit: single channel CTRL.1, MDR.S and one RT MK3.1 Brushless Lens Motor. You’ll probably use this kit for focus.

Teradek RT Three Channel Kit: one MDR.S, three RT MK3.1 lens motors, and one CTRL.3 hand unit. This kit controls Focus, Iris and Zoom.

If you left your hand unit behind at the last location, or just want to use your iPhone, the MDR.S has Bluetooth inside to control the lens with Teradek RT’s app for iOS.

The OLED display has a simple menu system.
Maximum line-of-sight range is 5,000 ft.
MDR.S is ridiculously lightweight: a mere 2.4 oz.
The camera control port allows users to start and stop recording from your RT hand unit.
