The Data Connect PE202T

To service the growing need for efficient, reliable data communication in harsh environments of utility substations and industrial facilities, DCE has developed a series of OEM PCB modems that can operate at 5V logic (TTL) or simple send and receive signals and survive high sure levels and extreme heat and cold. All this without compromising the performance expected from state-of-the-art communication devices. With the rapid move toward “intelligent” substations, where meters, relays, RTUs, SCADA systems, etc. are able to talk “talk” to a remote operator, communication devices such as modems are moving off the desktop and into the meters, RTUs, and SCADA units where the conveniences of a standalone modem is unacceptable. Data Connect Enterprise has addressed this problem by developing the PE2.4, 9.6FPD, 14.4, 14.4L, 202T, and 28.8 OEM modems designed specifically for harsh environments. The PE OEM modems are highly sophisticated full duplex, V.22bis data modems that are designed to interface with RS232, RS485 (external device), 5V logic (TTL) or simple send and receive signals. The PE2.4, 14.4, and 28.8 OEM modems operate at full or half duplex on dial-up line. The PE202T, 14.4L and 9.6FPD OPM modems operate full or half duplex on 2 or 4 wire leased line. The PE OEM Specs can be found in the MIU modems, MD modem cards and the MIU Powerport modems.
