Introduction to BT TAG This chapter aims to introduce you to RTX8210/RTX8212 BT TAG, its functionalities and how to connect it to your RTX8200 Location gateway. 2.
On the front side there is a sticker with a Data matrix barcode and the MAC address of the device. If scanned, the barcode gives information about the MAC address of the device, as seen on the label. The grey spot next to the sticker marks the button of the BT TAG, which serves for activating the device and sending beacons (See chapter 2.4.1 Button features for more details). 2.2.1 How to open the device The main purpose for opening the device is for changing the battery.
- Step 3: After opening the BT Tag, the following should be visible to the user On the inner side of the RTX8210/RTX8212 there is information about the product’s certificates, beacon and battery type, and more. There is a plastic plate under the battery which should be removed in order to activate the battery (see the picture below). Remove the battery and take out the plastic BT Tag GUIDE 4.
2.2.2 Mounting One of the main purposes of the BT Tag is to track objects, meaning that the Tag can be attached to them. Installing the device correctly will make a difference in the performance. The following is a general guideline on how to position the device for better functionality. The tag transmits approximately -3dBm of power and has a radiation pattern as shown on the image below.
On the contrary, a bad mounting solution in the same scenario would be placing the Tag in a horizontal way under the bed, as shown on the second illustration. By doing so, the signal strength will not be as strong and will be partly blocked by the bed. To make it easier and accessible for the user to attach the BT Tag to objects, RTX has added 2 extras. The device comes with a double-sided adhesive tape in the box that allows the user to attach it to any other object than ferromagnetic parts.
Despite the magnets, the user should avoid mounting the RTX8210/RTX8212 to a metal surface and instead use the tape to stick it to another available exterior, if possible. An example is shown on the Image 1 where the Tag is positioned on the wooden material, instead of the metal frame of the bed. 2.3 Power to device The RTX8210/RTX8212 uses CR2016 in order to have power and comes with the battery already in the device.
2.4.1 Button features The BT Tag has one physical button which handles the base function of the Tag, such as activating the device and sending beacons. Depending on the way the button is pressed, one of the cases will apply: • • • No press – when the button is not pressed and no movement is detected, the Tag is in sleep mode in order to save power.
The function is very useful when attaching the Tag to an object, such as hospital or technical equipment. By doing so, one can track if any of these objects have been moved to another room or out of the building. Moreover, the Tag is portable and can be carried by any employee which the company would like to keep track of. The device is programmed to detect the normal walking speed which is 1.4m/s, therefore if a movement is below 1.4m/s, a higher force will be required to wake up the BT Tag.
CHECKLIST FREQUENTLY ASKED QUESTIONS (FAQ) ▪ ▪ ▪ ▪ ▪ ▪ The Tag does not detect movement. What should I do? o Short press the button and a green LED will blink 3 times o Long press the button to activate the device o Change battery and activate the device There is no green LED when I press the button.

In order to deliver high quality services and products, RTX has made a calculation file which enables the user to measure the estimated battery life depending on the scenario.
As you can notice from the calculations above, the more the button is pressed, the more power it is consuming from the battery. As mentioned before, this is due to the LED that blinks every time the button is pressed. Moreover, the “Transmit interval in motion” is fixed and cannot be changed. It is present in the table, because it is used for the calculations. For more details about the calculation file, please contact RTX support. BT Tag GUIDE 4.
