Product Overview
Main Features
  • RS-232/RS-485 High-Speed Opto-Isolated Line Driver (LD485A-HS Opto-Isolated)
The perfect industrial line driver—speed, surge protection, and optical isolation, too The RS-232/RS-485 High-Speed Line Driver is versatile, reliable, and fast enough to use with all your high-speed equipment. It’s perfect for 4-wire half- or full-duplex applications, or for 2-wire half-duplex, point-to-point, or multipoint applications. And it enables you to link up to 64 devices via twisted-pair cable.

Because it has selectable settings, you can customize the driver for your application. Set line bias to match RS-485 equipment, such as industrial shipping devices. You can set the RS-485 driver to be enabled either by RS-232 control signals or by data, or to be constantly on. Select normal operation or loopback testing.

Surge-protection circuitry—transorbes, zener diodes, and inductors—guards the RS-485 side against induced surges. Optical isolation is comes on the ME838A-R3 to protect your data from ground-loop surges and interference caused by industrial machines. A port time-out feature prevents any single port from tying up your network.

These line drivers are transparent to data, and they can transmit data short distances at up to 115 kbps or as far as 4000 feet (6.4 km) at 1200 bps.

Features:
• We can customize for your application!
• Data rates up to 115kbps for high-speed industrial applications.
• Many user-selectable features.
• Surge protection built into RS-485 port.
