It can expand effective reading&writing range so that reduce hardware cost by connecting four different gain antenna outside. We originated controling lauching power separately in domestic that adapt to complex application circumstance. And we offer API function for convenient re-development. There are all kinds of communication interfaces and you can customize too.

Details:
1. Function brief introduction
Support multi-protocol: 9814 interrgator supports ISO18000-6B, EPC Class 1, EPC Class 1 GEN 2 standard, and also support many protocols and function expanding by through upgrading interrogator's software.

Label capability optimizing: NFC serial interrgators can optimize Label's operating used far-ranging. It uses different labels' expanding function to enhance the price-quality ratio of system's applying.

Out off line function: The interrogator is designed with nonvolatile memory place. When the interrogator fail to communicate with applying suetem, it can memory identified ID Label into the interrgator to make sure the system is stable.

ID match function: The interrogator is designed with nonvolatile memory place. In a close applying system, it can memory ID Label into the interrgator in advance. When the interrogator indentifies Label ID, It can compare with the ID memoried the local PC, then depending on the result, it can run the interrgator's predefining or user designing'action.

Synchronization function: In practice, many interrgators must be installed a near place, to make sure the reliability when interrgators working, NFC serial interrgators were designed especially with synchronization function to make sure the reliability of identifying label and reading rate.

Time function: There is real-time clock within interrgator, which can setup and read interrgator's time, identify time-stamp function under out off line. It can exactly satisfy the applying design that uses were sensitive for time.

Input and output function: The interrgator is designed 2-way triggering input, which can identify the label when occuring outer things to satisfy green environment protecting and decrease energy consuming. It is especial suitable for parking port and producing line manegement. It is designed 2-way relay output, which user can use for outer controling so that saving user's cost of applying system designed. User can transfer and control relay's switch status through the API function of NFC-interrgator SDK and also can customize the controling relationship according to the number of indentified Label ID.

Launching power separated control: Can setup separated every channel's launching power to meet applying and installing's complexity, which is the first designed and created in internal country.
