Description

TITAN’s USB2-4COMi-TB, USB2-4COMi-SI-TB, USB2-8COMi-TB, and USB2-8COMi-SI-TB USB2.0 to Quad/Octal industrial serial adapters are designed to make serial RS-422 and RS-485 port expansion quick and simple. Connecting to a USB port on your computer or USB hub, the USB to industrial serial adapter instantly adds four or eight RS-232/422/485 multi-electrical interface serial communication ports to your system. By taking advantage of the plug-and-play and hot-plug features of the USB bus, this industrial serial adapter makes it easier than ever to add four/eight industrial communication ports to your system.

Plugging the USB quad/octal industrial serial adapters to the USB port, the adapters are automatically detected and installed. There are no IRQ & COM port conflicts, since the port doesn’t require any additional IRQ, DMA, memory as resources on the system. The RS-232 or RS-422/485 port functions as native Windows COM port, and it is compatible with Windows serial communication applications. Each port is individually configurable. The adapters are designed with external switches to set RS-232, RS-422 or RS-485 ports and different operation modes conveniently.

The isolation and surge protection models (USB2-4COMi-SI-TB, USB2-8COMi-SI-TB) support 3000V DC optical isolation, 15kV ESD protection and 600W surge protection for all serial signals.
