LDM30 overview

  • Industry leading RS-232 serial line driver from Dataforth
  • Ideal for connecting RS-232 devices across long distances
  • Offers protection for your serial devices against power spikes and surges
  • Common mode isolation up to 500V DC surge
  • For data transmission up to 12 miles (20km)
  • Full data control lines including RTS, CTS, DTR, DSR
  • Full 4-wire duplex or 2-wire simplex mode available
  • Available with a pinned male DB25 connector (LDM30-P) or a socketed female DB25 connector (LDM30-S)
The LDM30 RS-232 serial line driver is designed to allow video display terminals (VDTs) and other RS-232 devices to be connected over distances sufficient to cover any industrial or institutional complex of buildings.

These limited distance modems feature a rugged aluminum enclosure small enough to mount on the back panel of VDT units, saving valuable desk and floor space.

The LDM30 line driver is designed for full-duplex, asynchronous operation over two, DC-continuity, non-loaded, twisted-wire pairs. Through special high speed optically-coupled circuits they may communicate at data rates up to 57,600 baud.

A self-powered model and a host-powered model are available. The self-powered unit uses 12V AC from a wall-mounted transformer while the host-powered unit takes ± DC power from pins 9 and 10 of the RS-232 connector.

The modem circuits - and, consequently, the host device - are protected from electrical transients due to lightning strikes or operation of heavy industrial equipment.
