CEP GT864-QUAD Terminal

The CEP GT864-QUAD Terminal is a self-contained GSM/GPRS Quad Band modem featuring advanced Telit technology, designed for system integrators focused on rapid application development. This professional-grade terminal operates across all GSM frequencies (850/900/1800/1900 MHz) with GPRS Class 10 capability, enabling fast data transfer on up to four simultaneous downlink channels and two uplink channels.

The terminal includes a built-in TCP/IP stack with comprehensive AT command access, supporting multiple sockets with listening/server capability, IPv4 protocol, FTP client, SMTP, and email services. Communication is facilitated through an RS232 9-pin D-Sub serial port, making it compatible with standard PCs and control boards in office and industrial environments.

Key connectivity features include SMS support in both text and PDU modes, Circuit Switched Data (CSD) up to 9.6 kbps, fax Group 3 Class 1 capabilities, and GSM 27.010 multiplexing protocol. The audio interface supports voice calls with headset connectivity, featuring multiple voice codecs (HR, FR, EFR, AMR), superior echo cancellation, noise reduction, and DTMF functionality.

Built for harsh environments, the terminal operates from -30°C to +75°C with storage temperatures ranging from -40°C to +85°C. It accepts a wide input voltage range of 5-36V DC, making it suitable for vehicle and industrial applications. The compact unit measures 77 x 67 x 26 mm, weighs approximately 100g, and features robust connectors with professional housing ideal for integration in vending machines, alarm systems, and telemetry applications.

The terminal includes three status LED indicators, an integrated SIM card holder supporting 1.8V/3V interfaces with SIM detection, and a 50 Ohm FME male antenna connector. Additional features include SIM Application Toolkit Class 2, real-time clock, jamming detection and reporting, and firmware update over-the-air capability. The device is E-certified, CE and FCC approved, RoHS compliant, and manufactured in Germany. An I/O variant with digital/analog inputs, digital output, and Python programming capability is available as the GT864 PY Terminal model.
