## Long description

The EXSYS EX-1335HMV USB 2.0 to 1S Serial RS-422/485 adapter provides a single high-performance 16C550-type UART compatible RS-422/485 serial port in a compact metal enclosure. It offers 15 kV surge (ESD) protection and 2.5 kV optical isolation to protect connected equipment, supports USB 1.1 and 2.0 hosts, and includes a USB A‑male to B‑male cable (EX-K1552) that can be secured with screws to prevent accidental disconnection. The adapter is powered by an FTDI chipset and is certified CE, FCC, RoHS and WHQL. Dimensions: 92.8 mm x 40 mm x 23.1 mm.
Advantages
The EX-1335HMV combines industrial-grade protection and a standard UART-compatible interface for reliable serial communication over USB without opening the host PC. It supports easy plug-and-play installation on PCs, thin clients or servers, provides hardware-level surge and optical isolation for safety, and comes with a screw-lockable USB cable for secure connections. Certification (CE/FCC/RoHS/WHQL) and compact metal housing make it suitable for industrial deployments.
Suitable for
Connecting RS-422 or RS-485 serial devices to PCs, thin clients or servers
Industrial control and automation equipment integration
Serial device management, monitoring and data logging

How to use
Install the adapter by connecting it to an available USB port on the host using the supplied EX-K1552 cable and secure the B‑connector with its screws. The device is recognized as a COM port by the operating system; I/O addresses and interrupts are managed by the OS and system BIOS (interrupt sharing supported). Attach the RS-422/485 device to the 9‑pin connector or terminal block as required and configure serial parameters (data bits, stop bits, parity) in the host software.
Usage recommendations
For reliable operation, mount the adapter in a stable location and use shielded cabling where possible. When deploying in racks, use the optional EX-6099 DIN-rail kit or appropriate rack-mount hardware. Configure matching serial parameters (7/8 data bits, 1/1.5/2 stop bits, none/even/odd parity) between the host and connected device before starting communication.
