New USB RS-485 Serial Adapter Designed For Extreme Environments
Sealevel Systems, Inc. announces the SeaLINK+485-DB9, a new single-port USB to RS-485 serial adapter that utilizes Sealevel's expertise in military-grade designs by incorporating a ruggedized, overmolded enclosure. The SeaLINK+485-DB9 offers fast, reliable serial communication for even the toughest environments, including factory floor, mobile, and outdoor 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+485-DB9 features programmable baud rate and data formats with 128-byte transmit and 384-byte receive buffers for fast, error-free communication. Each adapter includes a removable terminal block adapter (Item# TB34) that simplifies field wiring. Thumbscrews on the TB34 secure the terminal block adapter to the serial port and prevent accidental disconnection.

SeaLINK+485-DB9 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, and transmitting test pattern messages.

To meet the demands of working in harsh industrial environments, the SeaLINK+485-DB9 operates over an extended temperature range of -40 - +85°C. The attached 44” cable is fully shielded to protect the adapter from RF and EMI interference, which are common in mobile and industrial environments. The SeaLINK+485-DB9 serial adapter is available immediately from stock priced at $89.00 (Item# 2107). Like all Sealevel I/O products, the adapter is backed by a lifetime warranty.
