Introduction

A400 Active Device focuses on high-speed timing, and its excellent performance is widely used in cycling, roller skating, triathlon and other events. The device supports 8-meter timing areas on both sides, adopts a low-frequency wake-up and high-frequency transmission working mode, and it has strong anti-interference capabilities, making the data recognition rate and read and write accuracy higher.

1. Embedding 4 high-performance and high-frequency receiving modules, stable performance.

2. It can connect 2 sets of low-frequency coils, and stimulate active tags at the same time.

3. Single machine can support 8-meter timing area on both sides.

4. Dedicated highly penetrating wireless data link, synchronizing the internal clocks of all devices with one click.

6. The United States imported military-grade pelican box, which is sturdy and durable.

The low frequency coil is laid on the track through which athletes pass. lt is used to excite activetags, so that the active tags can transmit information to the active device's high-frequency receptionmodule. The maximum height for wearing labels shall not exceed 60 cm. it is recommended to wearit on the ankles for marathon track racing events. There are two common ways to use:(1) Use floormat glue to directly fix it on the track;(2) The coil is embedded the special floor mat and is laid onthe track.

It adopts an omnidirectional high-gain 2.4G antenna, which is installed on both sides of the low-frequency coil, and receives data sent by the active chip. Connect to the device via a high-frequency antenna extension cable.
