The workflows [Teradek RT CTRL.1 Single-Channel Hand Controller](https://specs-dev.teradek.com/products/prod.ctrl-1-single-channel-lens-controller.md) serves, how well it fits each, which slot it fills, and what else is needed.

## Core (1)

- CTRL.1 in [Wireless focus/iris/zoom (FIZ) lens control (draft: corrections pending)](https://specs-dev.teradek.com/workflows/wf.WF-14.md): fit core, role Lens control handset: Hand unit the focus puller holds; sends FIZ commands to an MDR receiver and motor., slot 1. control, 1 per lens axis (or 1 CTRL.1 per single axis; several RT units can control other axes of the same lens). Caveat: Range 1500 m (5000 ft, vendor) line-of-sight in USA/FCC mode, 150 m (500 ft, vendor) indoors; 2.4 GHz FHSS; the cited pages give no EU/CE-mode range. Single axis only. Also needed: [Teradek MDR.S](https://specs-dev.teradek.com/products/prod.mdr-s.md), [Teradek RT MDR.X 3-Axis Lens Control Receiver w/ Bluetooth](https://specs-dev.teradek.com/products/prod.mdr-x.md), [Teradek MOTR.S](https://specs-dev.teradek.com/api/third-party/tp.teradek.motr-s), [Teradek MOTR.X](https://specs-dev.teradek.com/api/third-party/tp.teradek.motr-x). Confidence: high.
## Supporting (1)

- CTRL.1 in [On-set zero-delay monitoring](https://specs-dev.teradek.com/workflows/wf.WF-09.md): fit supporting, role Mounts on the SmallHD monitor that shows the zero-delay video and sends lens maps for overlays; it does not carry video itself., slot 2. control, 1 per focus-puller monitor. Caveat: Overlays need a monitor interface cable, sold separately; the video is carried by the Bolt link, not by CTRL.1. \| Requires (as stated): Bolt TX/RX (video chain) Confidence: high.
## Not suitable (7)

- CTRL.1 in [Camera-to-cloud dailies and proxies](https://specs-dev.teradek.com/workflows/wf.WF-12.md): fit not suitable. Why: Carries no video or IP stream, so it cannot be the video, encoder, decoder or cloud element of this workflow.
- CTRL.1 in [Cloud video village / remote review on set](https://specs-dev.teradek.com/workflows/wf.WF-11.md): fit not suitable. Why: Carries no video or IP stream, so it cannot be the video, encoder, decoder or cloud element of this workflow.
- CTRL.1 in [ENG / breaking news live shot](https://specs-dev.teradek.com/workflows/wf.WF-01.md): fit not suitable. Why: Carries no video or IP stream, so it cannot be the video, encoder, decoder or cloud element of this workflow.
- CTRL.1 in [Live post review (editorial, HDR color)](https://specs-dev.teradek.com/workflows/wf.WF-13.md): fit not suitable. Why: Carries no video or IP stream, so it cannot be the video, encoder, decoder or cloud element of this workflow.
- CTRL.1 in [RF camera for live sports / IMAG](https://specs-dev.teradek.com/workflows/wf.WF-03.md): fit not suitable. Why: Carries no video or IP stream, so it cannot be the video, encoder, decoder or cloud element of this workflow.
- CTRL.1 in [UAV / public safety situational awareness (draft: corrections pending)](https://specs-dev.teradek.com/workflows/wf.WF-08.md): fit not suitable. Why: WF-08 is video from an encoder on a UAV or vehicle to a command centre. This product carries no video; its drone/gimbal mention only says the receiver is small enough to mount on such rigs.
- CTRL.1 in [Wireless camera control and live color](https://specs-dev.teradek.com/workflows/wf.WF-10.md): fit not suitable. Why: WF-10 is wireless camera control and live colour (LUT/CDL) to a DIT cart. This product only drives lens motors and, at most, camera run/stop; no colour or LUT path is documented.
