New USB RS-232 Serial Adapter Designed for Challenging Environments

Posted on

The SeaLINK single-port USB to RS-232 serial adapter utilizes Sealevel’s expertise in military-grade designs by incorporating a ruggedized, overmolded enclosure into the new SeaLINK-232-DB9. This enclosure improves reliability and durability in industrial and mobile applications such as GPS navigation systems, barcode readers, signature input devices, serial printers, scales, and similar applications.

The serial port appears as a standard COM port to the host computer enabling easy setup and providing compatibility with legacy software. The SeaLINK-232-DB9 features programmable baud rate and data formats with 128-byte transmit and 384-byte receive buffers. The USB serial adapter is compatible with all standard PC baud rates and supports high-speed communication to 921.6K bps. The adapter is powered by the USB port and status LEDs molded into the enclosure indicate serial data activity and connection to the host.

All SeaLINK USB serial adapters ship with Sealevel Systems SeaCOM suite of Windows drivers and diagnostic utilities. WinSSD, a full-featured application providing powerful testing and diagnostic capabilities, is also included. Use WinSSD for Bit Error Rate Testing (BERT), throughput monitoring, loopback tests, and transmitting test pattern messages.

Standard operating temperature range for SeaLINK adapters is 0°C – +70°C, and extended operation (-40°C – +85°C) is available. The attached 44″ cable is fully shielded to protect the adapter from RF and EMI interference, which are common in mobile and industrial environments. Like all Sealevel I/O products, the adapter is backed by a lifetime warranty.
