4 Port RS232 USB 2.0 to Serial Adapter with Optical isolation - Surge Protection
$228.95
Optical isolation and surge protection are available on serial port and is individually optically isolated with 2000 volt DC optical isolation on 8 signal pins, GND is isolated by 5V DC-to-DC converter. (GND cannot be isolated by photo-coupler.) meets the high level of optical isolation. The optical isolation protects your computer from spikes and surges, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse.
The USB2-4COM-SI-M USB to RS232 Serial Adapter is designed to incorporate Optical Isolation and Surge Protection with an industrial-grade metal case to ensure your computers safety. The USB2-4COM-SI-M can connect to a USB host port or USB hub to add 4 new serial communication ports to your system.
USB2-4COM-SI-M Isolated and Surge Protected Adapter
Plug and Play and Hot Plug features and adapts easily to new technology.There are no IRQ & COM port conflicts, since the port doesn't require any additional IRQ, DMA, memory as resources on the system. The RS232 port functions as native Windows COM port, it is compatible with Windows serial communication applications with each port individually configurable.
