ME99 is an embedded GPRS/CDMA IP DTU MODEM that supports multiple TCP/IP protocols, including TCP, UDP, DNS, PPP, etc. It supports a fully transparent transmission mode, which can completely replace the digital radio and minimize system upgrades. It supports dynamic IP resolution based on DNS protocol, which can save the cost of renting a fixed IP. It supports flexible networking methods such as point-to-point and point-to-multipoint.
The ME99 GPRS/CDMA IP DTU modem provides TCP/IP, UDP, DNS, PPP and other network functions over a 3.3 V RS‑232 interface. It supports SIM cards, serial communication at 9600 bps, and includes configurable server registration parameters.
The manual contains the AT command set, pin configuration, serialnet parameters, and instructions for setting up server address, port, and timeout values. It also lists hardware specifications such as dimensions, power supply, and connector details.
