SeaLINK DIN Rail USB serial interface adapters are the perfect way to add RS-232,
RS-422, or RS-485 serial peripherals such as barcode scanners, serial displays, and
data acquisition modules to any USB port.
Offering one or two DB9M serial ports, models are available for RS-232, RS422/485, and RS-232/422/485 interfaces. Serial ports are configurable via dip
switches accessible through the case. There is never a need to open the enclosure,
which simplifies field installation and service.
Optically isolated models prevent damage caused by surges and ground loops
commonly found in industrial environments. Status LEDs display transmit and
receive activity, and data rates up to 921.6K bps are supported.
The serial ports appear as standard COM ports to the host computer enabling
compatibility with legacy software. SeaLINK USB serial interface adapters are USB
bus powered, eliminating the need for external power supplies.
All models integrate the patent-pending SeaLATCH USB port, which is fully
compatible with standard USB cables. When used with the included USB cable with
a SeaLATCH USB type B connector, the metal thumbscrew provides a secure
connection to the device and prevents accidental cable disconnection.
Ready for DIN rail mounting, SeaLINK USB serial interface adapters include a
removable plastic clip that snaps onto 35mm DIN rail. The clip can also be attached
to a wall, under a counter, or inside a panel with optional screws.
