Installation 1. Unwrap the device wire harness but do not connect it to the device yet. Refer to the following picture of the TagLINK Bridge connectors when performing connections in the subsequent steps of this procedure. 2. If using the automotive type harness: ● Connect the red wire (pin #1) to positive 12/24v power (when installation is in Vehicle - via a 3A fuse to the vehicle battery (+30)). - In a vehicle installation, make sure this positive feed remains live even when the Ignition switch is turned OFF and when starting the engine. The fuse must be removed from the fuse housing during installation. ● Connect the black wire (pin #5) to the ground (-) power (in vehicle installation – to the vehicle chassis or any grounded part of the vehicle). - Make sure the connection is free of paint or dirt to assure a good conductive ground connection 3. If using a Micro USB cable: ● Connect the Micro USB cable to the plug and the other side to a USB power source. Micro USB connector 4 Pin Automotive connector Rubber seal and harness LED Indicators (Upper side) TagLINK Bridge Manual Rev-1.3 Page 5 4. To finalize the installation, Identify the desired location in which to install the device. Installation location should be clean, free of water, heat, and large metallic objects. For the best reception, install the TagLINK Bridge in an elevated position than the monitored elements. 5. Place the device in the selected location but do not affix it yet. 6. Secure the device in its preferred location. Remember, the flat bottom side opposite the LEDs can be attached to any surface. Choose your mounting method from the following options: a. Double-sided adhesive sticker: This is the easiest option for smooth, clean surfaces. b. Cable ties: Thread cable ties through the designated holes (if available) and fasten them securely to a suitable anchor point. c. Screws: Use screws if a permanent and sturdy mounting is necessary. Remember to choose screws appropriate for the surface material and ensure they don't damage the device. - Make sure the surface is clean and dry before using adhesive stickers. - For optimal signal reception, avoid mounting the device directly on metal surfaces. - Double-check that the device is level and securely attached before use. TagLINK Bridge Manual Rev-1.3 Page 6 3. Safety Instructions ● Personal safety is of paramount importance. Please follow all safety instructions when installing ERM products In a vehicle implementation: - Always disconnect power when performing installation by removing the negative connection of the vehicle battery. Never work when power is connected. - Always connect the positive wire using a 3A fuse. - Reconnect the external power only after the installation is fully completed, making sure all wires are safely insulated. - Use appropriate work tools. - Maintain good ventilation and lighting in the work area. - Never leave bare wires. Trim all wires not in use in such a way that no bare conductors remain, and fix them securely in place. - Perform installation in a dry environment. - Install ERM devices away from any heat sources. - Do not install ERM devices in the engine compartment or on the vehicle’s exterior. - Install ERM devices away from large metallic bodies and never install them in small gaps between metallic objects. 4. Troubleshooting 1. Device is Not Powering ON (No LED Indicator): - Check Power Connection: Ensure the device is correctly connected to the power source. - Inspect Power Supply: Confirm the wires are properly connected: black wire to GND, red wire to +12/24V, and green wire to IGN. - If there's no voltage, consider using an alternate power source. - Inspect for Damage: Verify the device does not show any signs of physical damage. 2. LED Indications: Follow the below indications to better understand the situation: Green LED Red LED Blue LED TagLINK Bridge Manual Rev-1.3 Page 7 Blue LED (Echo LED) has the following blink patterns: MODE LED Activity Description Advertising Mode First 30 seconds from waking up Bridge is advertising Echoing Mode Blinking, single speed Indicates the bridge has a tags packet in its buffer (transmission queue). It means that the bridge received Wiliot packets and forwards them on. Keep Alive Mode Two fast blinks in a row Indicates the bridge is alive (sends beacons management packets). When there is no energizing and no packets to echo. Red LED (Energizing LED) has the following blink patterns: MODE LED Activity Description Energizing Mode ON, if energizing is configured Indicates the bridge pattern includes energizing mode. OFF Indicates the current pattern used does not include energizing. Dual Band & Energies Energizing Mode Continuous This mode will only be active if energiz…
