SPORTident SRR USB Dongle
Description
The SPORTident short range radio (SRR) enables wireless transmission of SPORTident data records over distances of up to 6 metres. The radio is working in the licence free 2.4 GHz radio band and can be used worldwide. The following SPORTident products are enabled for SRR:
- Data sources:
- BSF8-SRR
- SIAC
- Data receivers:
- SRR radio dongle (connects to a PC)
- SIGSM-DN (GSM modem)
- LTE Modem
SI-SRR uses two radio channels (named “red” and “blue”) to achieve a robust data transmission with a low error rate. While the data sources use the two channels simultaneously, the data receivers always work at one and the same channel.
The SRR dongle receives data records sent from BSF8-SRR or SIAC. The device features an USB interface for easy connection with PC, laptop or other standard communication equipment.
The radio channel of the SRR Dongle has to be configured by Config+. To profit from the frequency agility of the SI-SRR, two receivers are strongly recommended, operating at the red and blue channel, respectively. For correct functionality it is important to verify that the receivers do not work on the same radio channel.
Using Config+ three more working parameters can be configured. While basic compatibility with standard evaluation software is kept, the data format “AIR+” offers specific information about the radio transmission. The basic protocol format skips this data and is fully compatible backwards. Data received by the dongle are forwarded automatically.
The SRR dongle typically works in ad-hoc mode as an always-on receiver. Each record received is accepted and forwarded to the host. There is no upper limit for data sources working in ad-hoc mode. Additionally, a logical radio link mode is supported by the SRR dongle. Up to eight logical radio links are possible.
Data received by the device can be computed by standard event software. Also Config+ features a simple monitor function to visualise the SRR functionality. Select the SRR Dongle as your target device and choose the feature “View punch”. This will bring up the following view. The dongle is ready to receive data.
