2. 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.

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.

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.
