Interface Card EXSYS EX-47200 Serial USB

The EXSYS EX-47200 Serial USB interface card provides a reliable connection between USB-enabled host systems and RS-232 serial devices. This compact adapter ensures stable data transmission and compliance with international standards through CE and FCC certifications. Designed for straightforward integration, it measures 62 mm in width, 32 mm in depth, and 16 mm in height, making it suitable for setups where space is limited. Operating efficiently across standard and demanding environments, it supports operating temperatures from 0 to 55 °C and storage temperatures from -40 to 75 °C.

Advantages

This serial interface card offers a driver-free installation process across all major operating systems, simplifying setup and reducing configuration time. It draws power directly from the USB bus, eliminating the need for an external power supply and minimizing cable clutter in your workspace. The device supports one RS-232 to TTL/CMOS port alongside a 4-signal conversion including TXD, RXD, RTS, CTS, and GND for dependable communication. Furthermore, its compatibility with 5V and 3.3V tolerance signals ensures flexible connectivity with various microcontrollers and legacy hardware.

Suitable for

• Connecting legacy RS-232 serial devices to modern USB ports
• Interfacing with microcontrollers and development boards supporting TTL/CMOS levels
• Industrial automation and control systems requiring compact serial communication
• Laboratory and testing environments where external power sources are unavailable

When it may not be suitable, this interface card is not designed for parallel port connections or multi-port serial requirements since it features only a single RS-232 port. It may also not fit enclosures or setups that require specialized internal mounting rather than standard USB connectivity.

Key specifications

• Interface: USB to RS-232 serial
• Supported signals: TXD, RXD, RTS, CTS, GND
• Port type: One RS-232 to TTL/CMOS port
• Voltage tolerance: 5V and 3.3V
• Power supply: Bus-powered via USB, no external power required
• Operating temperature range: 0 to 55 °C
• Storage temperature range: -40 to 75 °C
• Physical dimensions: 62 mm width, 32 mm depth, 16 mm height
• Certifications: CE, FCC

To use the device, connect the USB end directly to an available USB port on your computer or host system. Connect your RS-232 or TTL/CMOS serial device to the corresponding terminal of the interface card. Since the adapter requires no manual driver installation across supported operating systems, the system will automatically recognize the hardware, allowing immediate data communication.

What to consider before purchase

• Verify that your application requires a single RS-232 to TTL/CMOS connection
• Confirm physical space availability for dimensions of 62 x 32 x 16 mm
• Check that operating temperatures will remain within the 0 to 55 °C range
• Ensure your system utilizes compatible signal levels of 5V or 3.3V

Usage recommendations: Keep the device within the specified operating temperature range of 0 to 55 °C and avoid exposure to moisture or excessive dust to ensure long-term operational reliability.
