1. Product Feature

l        Standard industrial products, EMC anti-jamming design, strong adaptiveness.

l        Independent research and developing, embedded 32 bit ARM7-CPU with real-time operating system.

l        Support four frequency band: GSM850MHz/EGSM900MHz, DCS1800MHz/PCS1900MHz

l        Two working mode: SMS Modem (system default) and Modem. When set to Modem, single standard AT command (GSM07.05 and 07.07). When SMS Modem, user can set the message transmission with Single protocol or without protocol (Transparent).

l        Various networking ways: Under SMS Modem, the device with protocol (A) can network with the device without protocol (B), the device with protocol (A) also can network with the device with protocol (A).

l        Working temperature range: -40°C-80°C, communication is not effected at -40°C.

l        Plug and play: Reliable, flexible, easy to use and management

l        In these two modes, device can send the MAX data 512 byte a time to KB3023.

l        Under SMS Modem, support Sending and Receiving Data form: hex, ASC, UCS2. User is advised to set this parameter through our configuration software before use it.
