## Summary description

The EXSYS EX-47901 is a versatile RS-232 to RS-485 serial converter, repeater, and isolator. It features robust isolation to protect against electrical interference, ensuring reliable data transmission over long distances. With a compact design, it is easy to integrate into existing systems. Ideal for industrial applications, it supports various baud rates and is compatible with a wide range of devices.

## Long description

The Exsys EX-47901 is a versatile RS-232 to RS-485 serial converter, repeater, and isolator designed to provide instant serial port expansion for your PC, workstation, thin client, or server via a standard RS-232 port. Featuring a compact design, it is straightforward to integrate into existing setups and ensures reliable data transmission over extended distances. The device is equipped with a DB9 female connector for direct connection to an RS-232 port, converting unbalanced full-duplex RS-232 signals into balanced half-duplex RS-485 signals with robust electrical isolation.
Advantages
This serial converter offers reliable protection against electrical interference, ensuring stable communication in environments prone to electrical noise. Its dual functionality as a repeater and isolator helps maintain signal integrity over long transmission distances. The direct DB9 connection simplifies installation without requiring complex cabling adapters for standard RS-232 interfaces, and its compact form factor allows for seamless placement in space-constrained industrial or office environments.
Suitable for
Expanding serial communication ports on PCs, workstations, thin clients, and servers
Connecting RS-232 host systems to RS-485 industrial automation networks
Extending serial data transmission distances in monitoring and control setups
Isolating serial lines to protect sensitive computing equipment from electrical surges and interference
When it may not be suitable
This device may not be suitable if your application requires native full-duplex RS-485 communication, as the EX-47901 converts signals to balanced half-duplex. Additionally, it is not designed for non-serial interfaces or applications that require USB or Ethernet connectivity directly from the adapter.
Key specifications
Converts RS-232 to RS-485 signals
Functions as a serial converter, repeater, and isolator
Equipped with a DB9 female connector for RS-232 connection
Converts unbalanced full-duplex RS-232 to balanced half-duplex RS-485
Supported RS-232 pin configuration includes TXD input, RXD output, and Signal Ground
How to use
To use the Exsys EX-47901, connect the DB9 female connector directly to the standard RS-232 port of your PC, workstation, thin client, or server. Connect your RS-485 network lines to the corresponding terminals or output interface of the converter. Ensure proper power and signal wiring according to your system requirements. The unit will automatically convert the unbalanced RS-232 signals into balanced half-duplex RS-485 signals for reliable long-distance transmission while providing electrical isolation.
What to consider before purchase
Verify that your host system features a standard RS-232 port with a DB9 configuration compatible with the device
Check whether your application requires half-duplex RS-485 communication
Confirm the physical space requirements for installation based on the compact form factor
Assess your network distance and electrical interference levels to ensure isolation and repeater features meet your operational needs
Usage recommendations
Always verify pinout configurations and cable connections before powering on your connected equipment to prevent signal mismatch or potential hardware issues in industrial networks.
