The ELK-USB2404 4-port USB to serial adapter offers an easy way to connect multiple serial devices via a single USB port. The ELK-USB2404 uses a state-machine architecture that greatly reduces the host computer's overhead when communicating over multiple ports simultaneously. RS-232 data rates up to 921.6K bps are supported. The ELK-USB2404 is housed in a rugged, attractive plastic enclosure with a high-retention USB type "B" connector that prevents accidental disconnection of the included USB cable.The USB software drivers and utilities make installation and operation easy using Windows 98SE, ME, 2000, XP and Vista operating systems. After installing the software, the serial ports appear as standard COM ports to the host system enabling compatibility with legacy software. The ELK-USB2404 is USB bus powered, so no external power supply is required. For conveniently powering serial peripherals, ordering options allow an external power source 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.
