SL-2A1 module is one of our company's industry modules, specially aiming at wheel aligner R&D, design and production. Comparing with traditional one it has more advantages.
Most traditional wireless aligner modules use the light (the infrared ray and light) to transmit the data and information. However, because of the short transmission distance and the directionality of light that makes the shelter by operator, it is easy to cause unstable. Meanwhile, advanced Bluetooth module makes no barriers of information transmission and has improved the rate of accuracy of data transmission greatly. With Bluetooth technology, it can be installed into Wheel Aligner and computer, between which data transmission is accurate and clear in the range of 10 metres.
With FHSS technology, it can't be interfered by the same frequency signal of other equipment at repair place. It is unique comparing with traditional ones. Furthermore, Bluetooth module adopts omnidirectional antenna, more easily to find device. It Supports the terminal movement. Signal transmission is not affected by sight distance .It is full-duplex, supporting the connection of point to multi-point and facilitating to group network.
