Teradek’s MDR.S is a modular receiver with integrated Bluetooth for reliable smart device connections. MDR.S can command up to three daisy-chained motors for FI+Z control (Focus, Iris, and/or Zoom), offers camera control for ARRI, RED, Sony, and LANC-compatible models, supports all current Latitude functions and integrations, and features several configurable options accessible via the built-in OLED display.

POWER AND CONNECT
1. Connect power to the MDR.S’s power input (F).
2. Attach the motor(s) to the rods/lens.
3. Connect the motor to MDR.S motor input using a 4-pin to 4-pin cable. To connect multiple motors (up to three motors), use additional 4-pin to 4-pin cables to “daisy-chain” the other motors together. The motor(s) will then begin calibrating.
4. Use one of two methods to pair your controller with MDR.S
PAIR MDR.S AND CONTROLLER
If the controller you are using has not been paired with MDR.S, you can use one of the following methods to pair both devices.
Wireless Pairing via MDR.S
Press the MENU button on the MDR.S, then navigate to WIRELESS>CHANNEL and select the same channel number as the controller to begin pairing. The LED on both the controller and MDR.S will turn green once paired.
Wireless Pairing via Controller
Press the MENU button on the controller, then navigate to WIRELESS>FIND RECV to scan for active receivers and automatically pair. The LED on both the controller and MDR.S will turn green once paired.
CAMERA RUN/STOP
1. Connect a camera cable from the CAM port on the MDR.S to the camera, then navigate to MENU>CAMERA on the MDR.S and select which camera you have connected.
2. Press the REC/PWR button on the controller to start/stop recording on the camera.
NOTE: If using a RED camera, the camera serial communication setting must be set to RCP (Redlink Command Protocol) for the unit to operate.
MDR.S MENU OPERATION
Press the MENU button, then use the UP, DOWN, and SET button to navigate through the different menu options.

CONNECT VIA BLUETOOTH
1. Download the Bolt App.
2. Navigate to ADV>BLUETOOTH on the MDR.S, then select YES to enable.
3. Enable Bluetooth on your cellular device, then open the Teradek RT app. Your device will automatically detect your MDR.S if it is within range.
4. Select the RT device(s) you want to configure.
ASSIGN AN AXIS TO A MOTOR
1. Open the RT app, then select the device (MDR.S or controller) the motor(s) are configured to.
2. Tap the Settings icon on the top-right corner, select Device Settings, then scroll down to the motor you want to assign a specific axis to.
3. Tap the Class button to select an axis. From this menu, you can also configure the motor’s response speed and orientation.

CREATE A LENS MAP
1. Open the RT app, then select your MDR.S from the main screen.
2. Tap the Settings icon on the top-right corner, select Lens Mapping, then tap the Create New Lens Map button at the bottom of the screen.
3. Select the lens manufacturer, then create a name to identify the lens map.
4. If the lens is a prime lens, tap the Prime Lens switch, then enter the Focal Length (e.g. 35mm, 85mm).
5. Select the axis you want to map (Focus, Iris, Zoom). Make sure a motor is attached to the corresponding ring, and that both the motor and MDR.S are set to the same axis.

6. Move the virtual knob for the motor to adjust the lens ring to the smallest mark.
7. Using the Up and Down buttons on the right, enter the corresponding mark, then select Insert. Repeat this step for all marks until they have all been mapped.
8. Press the Back button to select additional axis to map. Repeat steps 5 and 6 for each axis you want to map.
9. Press the Back button once more, then tap Save at the top right corner. You will then be prompted whether or not to apply the Lens Map.
