RTD Embedded Technologies, Inc. | www.rtd.com 7 COM16155ER/COM16155RER User’s Manual
1 Introduction
1.1 Product Overview
The COM16155 is designed to provide quad-band GSM and GPRS with global positioning system (GPS) for PCI/104 based systems. Included
on the COM16155 are a Cinterion MC55i-W quad band GSM cellular modem and a Linx RXM-GNSS-TM GPS Receiver module. The
COM16155 has an ISA UART chip that permits communication with serial port on the GSM as well as the serial port on the GPS receiver
module over the PCI/104 bus without using other serial ports in the PC/104 system. The GSM module supports an enhanced AT command set
and the GPS supports National Marine Electronics Association (NMEA-0183 ver. 4.10) messages.
The COM16155R uses the Triorail Tri-band GSM cellular modem instead of the Cinterion MC55i-W for railroad applications.
