December 4, 2008 -- Sealevel Systems has released additions to its SeaLINK USB to serial product line. The SeaLINK/PC.SC (one-port) and SeaLINK+2/PC.SC (two-port) embedded USB to serial adapter with a PC bracket are designed to add serial ports to any PC, using the computer's internal USB connection. The serial ports are software configurable for RS-232, RS-422, or RS-485, which the company says eliminates the need for an external converter and provides a clean, professional installation.
According to Sealevel, all configuration and electrical interface selections are handled through the adapters' driver software,so the user doesn't need to shut down the computer or open the system enclosure to set jumpers or dipswitches. Additionally, the devices maintain their electrical interface settings in hardware, allowing the host computer to be repaired or upgraded without reconfiguring the serial ports.
The serial ports on each SeaLINK adapter appear as standard COM ports to the host computer enabling compatibility with legacy software. The SeaLINK USB serial adapters use a state-machine architecture that reduces the host computer's overhead when communicating over multiple serial ports simultaneously while supporting data rates to 921.6 Kbps.
All SeaLINK products ship with the Sealevel Systems SeaCOM suite of Windows drivers and diagnostic utilities. The proprietary WinSSD application, which provides testing and diagnostic capabilities, is also included and is used for BERT [Bit Error Rate Testing], throughput monitoring, loopback tests, and transmit test pattern messages.
Standard operating temperature range for the SeaLINK products is 0 - +70 deg C; extended temperature range (-40 deg - +85 deg C) models are available. Both models include a standard sized PC bracket and ship with an internal USB cable (Item# CA260) that is compatible with ATX, Mini-ITX, and similar large motherboards with 0.1" USB header connectors. For smaller motherboards, an internal USB cable with a 2-mm header connector (Item# CA383) is available as an option.
Both items are available from stock, priced at $179 for the SeaLINK/PC.SC (Item# 2128) and $229 for the SeaLINK+2/PC.SC (Item# 2228).
