The TD-34 is a top of the range modem designed for use in the most extreme of industrial environments. This modem is the result of over 25 years of experience in the industrial telecommunication market. The modem is suitable for use at extreme temperature ranges (–40 to +70°C) and can be used to altitudes of 4000 m.
The TD-34 is a V.34 analogue modem meaning that it can support line speeds up to 33.6kbit/s – the fastest analogue to analogue modulation possible. With a terminal data speed of 115.2kbit/s the modem can be used for high data rate applications.
A “Fallback” mode is supported when using leased lines. In the event of a line failure a PSTN connection is negotiated and then periodically the leased line is checked until connection can be re-established. The TD-34 has as standard both RS-232 and RS-422/485 ports although only one can be used at any time. There are two variants of the TD-34 for different power supplies, the LV (12–54VDC, 12–27 V AC) and HV (95–240V AC 110–240 V DC).
