|Wintec's embedded data modems feature fast connect modes, parallel phone detection, line-in-use monitoring, caller ID and excellent surge immunity. Embedded modems are used in a number of applications such as point-of-sale (EPOS), alarm panel, medical equipment, transportation, wind energy and remote monitoring. Wintec has implemented two different interfaces to meet various customer demands. One is parallel mode interface where the data transactions between the host and the modem use an 8-bit data bus with a set of micro-controller signals at the interface. The other uses an UART interface, where the embedded modem operates in serial mode to handle data transfer with the host system.
