    DW(100)9811 interrogator is a kind of 915M RFID interrogator, which is full frame and function. It includes RF module, digital signal managing, input/output port and series communication port, synchronization function.

    DW(100)9811 interrgator is multi-protocol UHF interrgator, which supports ISO18000-6B and EPC potocol international standard it can read and write UCODE, TI, Alian and othes label, besides it can optimize main applying label clip. It is convenient to upgrade interrogator's software to satisfying protocol expanding and function expanding to protect user's investment.

Application Usage
DW(100)9811 interrogator is applied to not parking and charging fee management of high-speed road(bridge), indentifying car's brand management, cars' management of organizing into groups and attempering, management of intelligent park, management of checking cars' entering and leaving frontier, supervising material's being out and in and identifying management, baggage and package's identifying management and containers on dock management and other fields.

Function brief introduction


· Support multi-protocol: DW(100)9811 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:Doowa series 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, Doowa series 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 Doowa-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.
