Sealevel Systems, Inc. has added two devices to its USB serial server family, designed to link to up to 16 independent serial ports for access to multiple peripherals such as barcode scanners, serial displays, and data acquisition modules.
The serial ports on each SeaLINK+16 appear as standard COM ports to the host system enabling compatibility with legacy software.
The USB serial servers use a state-machine architecture to reduce main processor overhead when communicating over multiple ports simultaneously.
Data rates up to 921.6K bps are supported, and the SeaLINK+16/485 offers RS-232/485 selectivity through cabling. Two convenient USB 1.1 downstream connections are also provided to allow daisy chaining SeaLINK devices or interfacing standard USB peripherals.
