Description

MIU202T

Bell 202T continues to be the standard of choices in many utility and industrial multi-drop data communications applications. The Data Connect Enterprise MIU202T can be powered from a wide range of DC and AC voltages, is surge protected on both the power and analog lines, and will operate in extreme heat and cold. Ideal for multi-drop applications over leased lines and private lines.

The MIU202T is a Bell Standard 202T modem designed for asynchronous operation at 0 to 1200 bps over voice grade lines and pilot wires. The modem is intended for use on leased lines and private lines and provides half-duplex communications on 2-wire lines, or full-duplex on 4-wire.

Most modem manufactures have abandoned the Bell 202T in favor of the much higher speed modulation preferred in dial-up systems. However, Bell 202T remains the standard of choice in many utility and industrial applications where relatively small amounts of data are to be transmitted in multi-point networks.

To meet this continued demand, Data Connect Enterprise has added the MIU202T to its range of Communications Interface Units (see separate brochure).

The MIU202T can be powered from any AC or DC voltage in the range of 48V to 220V.A 9-36VDC version is also available. It is designed to work extended temperatures ranging from -40C to +80C, and its surge protected to 8kV, double the voltage requirements of IEC801-4 standard.

All of this is bundled in a 5-3/8“x 4” x 1-3/8,’ non metallic enclosure, suitable for desktop or wall mounting. Rack mount cards are also available for Data Connect Enterprise “Myriad” system (see separate brochure)
