1 Introduction

Welcome to the Blū Revolution! Your CTT BlūSeries Receiver provides up to four (4) 2.4GHz radio channels for you to detect BlūSeries tags. These include the groundbreaking BlūMorpho tag (weighing as little as 0.06g and totally battery-less!) and the BlūBat tag, a new battery-based tag weighing as little as 0.16g and able to last 76 days beeping every 5 seconds! There are a few things you should know about your BlūSeries Receiver, and we’ve compiled them below.

2 Unboxing your BlūSeries Receiver

2.1 What’s in the box

  • BlÅ«Series Receiver with Case
  • USB-to-Ethernet Adapter (to connect the receiver to your CTT SensorStation)
  • Hardware (4x Bracket Bolts, 4x Bracket Nuts, 1x Wire Holder, 1x Screw, and 1x Cable Gland)
  • Top and Bottom Mounting Plates
Everything included with the purchase of a CTT V3 Node
Everything included with the purchase of a CTT V3 Node

2.2 What you’ll need

  • Ethernet Cable: CAT-5 up to CAT-8 will work. Any length under 100m. Choose a cable without a covering on the ends as this will make it difficult to impossible to fish through the cable glands and into the Receiver and SensorStation.
  • Coaxial Cable(s) for antenna(s)
  • 2.4GHz Antenna(s)
  • Pipe clamps or similar for attaching the mounting plates to your mast

2.3 Tools

This assumes you have a CTT SensorStation with a pre-existing cable gland for getting the Ethernet cable into the SensorStation. If not, you will also need a drill and circular bit for the dimension of whatever cable gland you choose. If you purchased a new CTT SensorStation with this receiver your case should provide a pre-existing knock-out for installing your cable gland.

  • #1 and #2 Phillips-head Screwdrivers
  • Coax tape
  • 2x Crescent Wrenches

3 Assembly

3.1 Installing the Ethernet cable and Cable Gland into the CTT Node V3

  1. Unscrew the Node V3 case using a #2 Phillips screwdriver. Open the Node lid and place the lid and screws to the side.
  2. Unscrew/disassemble cable gland into its 3 plastic pieces

Disassembled Gland. Note: The rubber grommet still inside of the main component (middle)

  1. Push out the rubber grommet from the main gland component
  2. Put the split grommet around the Ethernet cord (with the tapered end of the grommet facing away from the working end of the cable).
  3. Insert the Ethernet cable into the gland’s main housing (starting from the “toothed” end of the connector). Some force may be required, but take care not to break the Ethernet cable end.
  4. Fish the grommet into the connector and be sure the grommet is circular, uniform and not deformed.


Partially Assembled Gland on Ethernet Cable. Note: The end of the ethernet cable that will ultimately be plugged into the Node is displayed here.

  1. Put the threaded cap onto the opposite end of the cable, bring it towards the end that you have already started connecting. Thread on the connector a couple of turns until the gland is on the wire snug but can still be slid up and down with some force.
  2. Insert the partial cable/gland assembly into the case with the recently “capped” part of the gland on the outside of the case.

Important: Make sure that the Ethernet cable stays under the 4 wires running from the printed circuit board (PCB) to the bottom of the case. Also, for best performance, be sure the Ethernet cable is not twisted or kinked from the gland to its connection onto the PCB.

  1. Inside the case, thread the last piece of the gland onto the rest of the gland assembly. Tighten fully either by hand or with a couple of crescent wrenches.
  2. Feed the Ethernet to the back of the case, as shown above.
