Product information

Description

The EXSYS EX-47920 is a compact RS-232 serial converter, repeater, and isolator designed to enhance communication stability and protect connected devices in demanding environments. Weighing only 200 g and measuring 49 x 41 x 22 mm, this device ensures reliable data transmission over long distances while providing essential electrical isolation and surge protection. It is compatible with both new and legacy RS-232 equipment, making it a versatile addition to any professional setup.

Advantages

The EXSYS EX-47920 provides a reliable electrical isolation solution that protects your computer and serial equipment from ground loops and electrical surges. Its compact dimensions allow for easy integration into space-constrained installations without adding clutter. The device supports hot-swapping, enabling installation and removal without shutting down your computer or server. By extending transmission distances and reducing noise interference, it ensures consistent and stable data communication across industrial and office setups.

Suitable for

  • Connecting legacy RS-232 serial devices to modern PCs and workstations
  • Protecting sensitive serial equipment from electrical surges and ground loops
  • Extending RS-232 communication distances in industrial environments
  • Maintaining stable data transmission in electrically noisy areas

When it may not be suitable

This device is not designed for non-serial interfaces such as USB, Ethernet, or parallel ports, and it will not function as a protocol converter for different interface standards. It is also unnecessary for short-range serial connections within a controlled environment where electrical interference and ground loops are entirely absent.

Key specifications

  • Interface: RS-232 to RS-232
  • Connectors: DB9 female (DCE port) to DB9 male (DTE port)
  • Signals supported: TXD, RXD, GND
  • Operating humidity range: 5% to 95%
  • Dimensions: 49 x 41 x 22 mm
  • Weight: 200 g

How to use

To use the EXSYS EX-47920, connect the DB9 female connector directly to the RS-232 port of your PC, workstation, thin client, notebook, or server. Connect your serial peripheral cable to the male DB9 connector on the other side of the isolator. The device supports plug-and-play installation and hot-swapping, meaning you can connect or disconnect it while your computer is powered on, without requiring any additional software configuration or driver installations.

What to consider before purchase

  • Verify that your devices utilize standard RS-232 interfaces with DB9 connectors
  • Check that your application requires signal lines TXD, RXD, and GND
  • Confirm the physical space availability for the 49 x 41 x 22 mm unit

Usage recommendations

Always ensure secure screw fastening on the DB9 connectors to maintain a stable electrical connection and prevent accidental disconnection during operation in high-vibration environments.
