OEM MODEM MODULE - TTL MMCX Datasheet Overview Introducing the OEM-GPRS-2E embedded modem module, specifically designed for machineto-machine (M2M) applications. It enables remote equipment with simple I/O or serial protocols to communicate over GSM and GPRS networks and is ideal for standalone applications where there is no external microcontroller. The OEM-GPRS-2E is footprint compatible with Comtech M2M’s standard modem module footprint and connectors, offering a roadmap for supporting other networks (Ethernet, PSTN) and greater system level functionality. It offers full data and audio in a small low power module. Solution OEM-GPRS-2E enables host equipment to communicate over the GSM and GPRS networks. It includes an on-board TCP/IP stack with listening and client sockets enabling legacy protocols to be transported via IP networks such as GPRS and the Internet. Four variants are available, which allow connection to TTL or RS232 compatible equipment interfaces & MMCX or SMA RF antenna connections. The OEM-GPRS-2E supports extended AT-Commands for establishing and controlling connections. Where the host equipment is unable to control the connection, it supports auto-dial and auto-answer features. OEM-GPRS-2E is able to remain in low power sleep mode until a wakeup event occurs. Once awake, the module can perform a number of automated operations before re-entering low power sleep and standby modes. This includes start / monitor timer sequences, SMS and data autodial features. It can wake from an on-board real-time clock (RTC) and host signals (data, DTR). |
