Description

The LD-01 is a four-port line split modem allowing RS-232 systems to be connected in multidrop applications over long distances. The interface can be either standard RS-232 or W1, a balanced current loop allowing transmission distances up to 18 km (11.18 mi). In multidrop applications, the LD-01 acts as a repeater on the W1 interface.

DIP switches are used for configuration options which make the unit simple to install. The serial interface is connected through a standard 9 pol D-sub or terminal block with screw connectors.

The LD-01 is designed for use in heavy-duty industrial applications. The different power options, galvanic isolation, and transient protection guarantee communication in the worst environments. The LD-01 has been tested to meet many EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments.

The design of the line split modem makes the LD-01 suitable for a variety of applications with various speeds and data bit options. The V and Y mode emulate half or full duplex communication between master and slaves and a bypass board can be fitted to ensure networks can’t be broken by power failure at a single point.


End of Life Product - No Replacement

Please note that the LD-01 has been phased out. You can explore other types of modems in the Modems.
