Introduction
The Sealevel Systems SeaLINK+8/232.RJ (Item# 2804) is a USB device that equips
the PC with eight RS-232 Asynchronous serial ports that support TX, RX, RTS, and
CTS and data rates up to 115.2K baud. The 2804 is housed in an attractive plastic
enclosure with a high-retention USB type "B" connector that prevents accidental
disconnection of the included USB cable.
The 2804 is USB bus powered, so no external power supply is required. For
conveniently powering serial peripherals, ordering options allow an external power
source up to be connected to a DC jack on the rear of the unit. The supplied power is
fused and connected to pin 5 on each of the eight RJ45 connectors.
The SeaLINK+8/232.RJ is designed to be used with a variety of Operating Systems
including Windows 98/ME/2000/XP. The SeaCOM API (Application Programmer
Interface) included on CD with the SeaLINK+8/232.RJ provides a variety of useful
high-level function calls implemented as a Windows dynamic link library (DLL). In
addition to the API, SeaCOM includes sample code and utilities to simplify software
development.
