Overview
GPRS/GSM modem with isolated digital I/O channels & 20W (5V/4A) power supply. Micronix PV-1820 offers a unique combination of GSM/GPRS mobile communication with integrated power supply and I/O provides a cost-effective and space saving PC/104 solution for GSM/GPRS applications. Micronix PV-1820 is a low-power GSM/Cellular modem using Sony Ericcsson’s GM47 dual band (900/1800MHz) cellular engine. The PV-1820 can be controlled by AT commands and is fully compatible with the AT command set. The PV-1820 also includes a power supply, which provides 4A at 5V for external use, thus you do not need an extra power supply for your system. 8 digital inputs and 7 digital outputs (all opto-isolated) allowing the user to control auxiliary equipment. Events can be reported thru the SMS feature on the GSM modem. An on-board SIM card socket provides a fast and reliable integration of your SIM card without any cabling or customisation. A free of charge software lets you easily install and configure the SIM card, including PIN code setting. Micronix PV-1820 represents the latest development within GSM technology and holds all the necessary approvals (R&TTE and GCF), thus PV-1820 is recommended for all new designs. The PV- 1820 is ideal for all PC/104 based data logging and alarm systems. The PV-1820 withstands extended temperatures, shock and vibration of mobile equipment More for less Micronix PV-1820S is approximately 25% lower priced than other GSM/GPRS PC/104 modems and provides more features than any other PC/104 GSM/GPRS modem available on this form factor.
