OSSM Controls

Control Screen Overview

When connected to an OSSM, the control screen displays:

• Top: Three tabs showing Depth, Sensation, and Stroke modes
• Top Bumpers: << and >> buttons for mode switching
• Left Side: Speed encoder dial with arc indicator
• Right Side: Mode encoder dial (Depth/Sensation/Stroke) with arc indicator
• Center: Linear rail graph showing stroke and depth visualization
• Below Graph: Current pattern name
• Bottom: Menu, Pause, and Patterns buttons

Speed Control

The left encoder always controls speed, regardless of which mode is active.

• Turn clockwise to increase speed
• Turn counter-clockwise to decrease speed
• The encoder has acceleration: faster turns make bigger changes

Adjustment Modes

The right encoder controls one of three parameters, depending on which mode is active. Use the shoulder bumpers to switch modes.

Depth Mode

Controls how deep the penetration reaches.

• Higher values = deeper penetration
• The depth is visualized on the linear rail graph

Sensation Mode

Controls the intensity or "feel" of the motion.

• Lower values = gentler, smoother motion
• Higher values = more intense, aggressive motion

Stroke Mode

Controls the length of each stroke.

• Lower values = shorter strokes
• Higher values = longer strokes
• The stroke is visualized on the linear rail graph

Switching Modes

You have two ways to switch between Depth, Sensation, and Stroke:

Using Bumpers (Recommended)

• Left Bumper (<<) — Switch to the previous mode
• Right Bumper (>>) — Switch to the next mode

The mode order is: Depth → Sensation → Stroke → Depth...

Visual Feedback

When you switch modes:

• The corresponding tab at the top becomes highlighted
• The right encoder LED color changes:
  • Coral/Red — Depth mode
  • Blue — Sensation mode
  • Green — Stroke mode
• The left encoder LED stays purple (always speed)

Pause and Stop

The middle button controls pausing and stopping.

Single Press: Pause

A single press pauses the OSSM:

• Speed is set to 0%
• The pattern name changes to "Paused" in red
• The middle LED turns red
• The Pause button changes to "STOP" (red)

Safety Feature: Persistent Speed Monitoring

When you enter Pattern Mode or other menus, RADR continues to monitor the left encoder (speed) for safety. This means:

• You can still adjust speed while browsing patterns
• If you turn the speed to 0, the OSSM stops immediately
• This ensures you always have instant stop capability

Hold: Device Stopped

On the Stroke Engine control screen, press and hold the middle button for about a second to stop:

• Speed is set to 0%
• The "Device Stopped" screen appears
• Your depth, stroke and sensation settings are kept

On the Device Stopped screen, press Back (left) or the middle button to return to the controls, then turn speed up to continue. Press Home (right) to disconnect from the OSSM and go back to the main menu.

Pattern Mode

Press the right button (Patterns) to enter Pattern Mode.

In Pattern Mode:

• The screen shows a list of available patterns
• Use the right encoder to scroll through patterns
• Press the right button to select a pattern
• Press the left button to cancel and return

See Stroke Patterns for details on each pattern.

Linear Rail Graph

The linear rail graph in the center of the screen provides a visual representation of the OSSM's motion:

• The graph shows the stroke range and depth position
• As you adjust Stroke and Depth, the visualization updates in real-time
• This helps you understand the physical motion without looking at the machine

Menu Button

The left button (Menu) is reserved for future OSSM device settings.
