Compact MODUS3 X USB RS232 interface module by custom, model 915LF020200300

The Compact MODUS3 X USB RS232 interface module by custom, model 915LF020200300 provides USB-to-RS232 connectivity in a compact enclosure. Designed to connect legacy serial equipment to modern USB-enabled systems, this interface module enables reliable data exchange and device integration in situations where a native RS232 port is not available. The unit is intended for environments such as industrial automation, laboratory instrumentation, and field service where serial communication remains necessary.

Advantages

The module offers a small footprint and straightforward USB connection that reduces the need for additional adapters or system modifications. It supports standard RS232 signal levels and provides a stable serial link for data transfer, simplifying integration of instruments, controllers, and measurement devices. Its compact design facilitates installation in constrained spaces and on workbenches, while compatibility with common operating systems ensures broad interoperability.

Suitable for

• Connecting legacy RS232 instruments to modern PCs and laptops via USB
• Industrial automation systems that require serial device interfacing
• Laboratory equipment data collection and control
• Field service, diagnostics and equipment commissioning tasks

Key specifications

• Interface type: USB host to RS232 serial
• Form factor: compact module suitable for tight installations
• Signal support: standard RS232 voltage levels and control lines
• Data rates: supports common serial baud rates used in device communication
• Power: bus-powered from USB connection
• Compatibility: works with common operating systems that support USB serial adapters

How to use

Connect the module to a USB port on the host computer and attach the RS232 cable to the serial equipment. Install or enable the appropriate USB-serial driver on the host if required by the operating system. Configure the serial port parameters on the host (baud rate, parity, data bits, stop bits and flow control) to match the connected device. After proper driver installation and port configuration, the host application can open the serial port and exchange data with the RS232 device.

Usage recommendations

Use shielded RS232 cabling and secure connections to minimize electrical noise and ensure reliable communication. Verify and match serial settings between devices before initiating data transfer. For continuous industrial use, place the module where it is protected from excessive vibration, moisture and temperature extremes.
