Sealevel Systems, represented in Australia by Allied Data Systems , has announced two additions to the SeaLINK USB to serial product line, the SeaLINK+4M.SC and SeaLINK+8M.SC.
The devices offer four or eight serial ports that are software configurable for RS-232, RS-422, or RS-485, eliminating the need to open the enclosure to change jumper settings or dipswitches.
The devices maintain their electrical interface settings locally, allowing the host computer to be repaired or upgraded without reconfiguring the serial ports. Additionally, the devices can be configured at one computer and deployed to other computers.
The serial ports on each SeaLINK adapter appear as standard COM ports to the host computer enabling compatibility with legacy software.
All Sealevel 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 921.6Kbps.
Status LEDs on the front of the enclosure indicate power, serial data activity, and electrical interface. The SeaLINK+4M.SC and SeaLINK+8M.SC are housed in rugged metal enclosures and include two convenient USB 1.1 hub ports for easily connecting additional SeaLINK devices and other standard USB peripherals.
These adapters integrate SeaLATCH locking USB ports, which are fully compatible with standard USB cables. When used with the included USB cable with a locking type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection. Both USB hub ports can also be secured using optional SeaLATCH USB cables.
All SeaLINK products ship with the 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 BERT (Bit Error Rate Testing), throughput monitoring, loopback tests and transmit test pattern messages.
