Looking for a Tam Valley Depot Octo III? One of the QuadLN_S operating modes has 8 servos and 8 inputs for fascia controllers or pushbuttons. There are two pre-configured versions of the QuadLN_S available with everything preset for you. All 8 servos can be adjusted using a QuadLN_S Remote Align board – no LocoNet or JMRI required for this basic functionality. If you don’t have LocoNet and only want to control your servos using fascia controllers then check out the pre-configured versions on the QuadLN_S Board page.

The QuadLN_S product family – Servos, Detectors and Signals

QuadLN_S LocoNet stationary decoder is the heart of the system and handles servo control, inputs, outputs and LocoNet communications. Provides complete turnout control using compact SG90 servos. Supports optional Detector and Signal add-on boards. Fully configurable using JMRI. Operates on a conventional LocoNet with a command station or on a standalone LocoNet that has no command station. Firmware updates performed using JMRI (Remote Align board required to initiate a firmware update).

Detector Board add-on for 4 channels of current detection with individual channel sensitivity adjustments. Includes 4 detectors mounted on their own boards with screw terminal for easy wiring.

Signal Board add-on for 24 LED outputs with realistic effects for Searchlights, CPL signals and crossings.

See the individual product pages for more information or download the Version 2 or Version 3 packages below and get the manuals for all 3 boards.
