Indiemark 2 Lens Encoder

Indiemark Encoder Overview

On this page, we'll go over the setup and operation of the Indiemark 2 Lens Encoder.



  1. Zero Button
    • Used to reset the encoder to Zero
  2. LED indicator
    • Indicates status of encoder
  3. USB Cable Clamp
    • Securely holds USB-C connector and protects it from damage
  4. Rod Clamp
    • Mounts encoder onto 15mm or 19mm rods
  5. Lens Gear
    • Interfaces with cine lens gearing

LED Indicator

Effect Description
Breathing Orange Power applied, but unable to enumerate USB
Pulsing red Encoder is not zeroed
White Encoder is at or near it's zero point
Fading blue Normal operation

Physical setup

Choose the gear that correctly interfaces with your lens. Gears can be replaced by using a 1.3mm allen wrench.

Select the rod clamp that fits your setup, and slide it onto the clamp track. Tightening the knob will lock the clamp. When first powered on, the encoder will pulse to indicate it needs to be zeroed.

It doesn't matter which side of the lens you mount the encoders. When you Zero the encoder, it will report positive values no matter which direction it is spun.

Set the lens to the following settings:

  • Focus: Close focus
  • Iris: Widest aperture
  • Zoom: Widest focal length

Once set, press the Zero button to zero the encoder. You are now set.

USB Cable Clamp

Loosen the two thumbscrews to insert a USB-C cable (included.) Once the cable is plugged in, finger tighten the thumbscrews to clamp the connector securely. The USB clamp is optional and can be removed by removing the two allen screws on the side of the encoder. This allows thicker cables or right angle connectors to be used.

LONET 2 Server Software

The LONET 2 Server software is used to detect, manage, map, and output data from Indiemark Lens Encoders. It can be downloaded for free, and will auto-detect Indiemark encoders on startup. More details can be found here.

Indiemark Network Relay

The Indiemark Network Relay utility (built with VPOS) can be used to send Indiemark encoder data via a wireless or wired network, enabling the remote use of Indiemark encoders by plugging them into a Mini PC.

The utility can be started with RUN.BAT. When running, any Indiemark encoders will be detected and sent to LONET 2 via the standard LONET multicast IP. They can then be mapped just as if they were connected via USB.

The utility can be set to start automatically on system bootup. We reccommend the GMKTec NucBox line of Mini PCs.

Using Multiple Encoders

An easy way to connect multiple encoders to one camera is to connect them all to a USB hub, and then run an active USB cable back to the PC.
