9600/1200 BPS USB HART MODEM


Smart Embedded Systems (SES), Inc., a Silicon Valley Company, is producting the industry’s first Dual speed HART USB modem. SES, one of the pioneers in firmware based modems, has developed a very compelling and cost effective, patented dual speed Modem technology/solution for Industrial Automation applications. Our USB modem design is incompliance (registration pending) with HART “C8PSK and FSK Physical Layer Specifications" as defined in HART 6 Specification. With our 9600 bps modem, we support the Industry standard HART Communication Protocol (HART Stack 7.0) while offering at least 5 times the number of packets per second as well as the current FSK 1200 bps.
