USB 2.0 to 4 Port Industrial RS232 Serial Adapter
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 port functions as native Windows COM port, and it is compatible with Windows serial communication applications. Each port is individually configurable.
The USB 2.0 4 Port Serial Adapter with Metal Chassis provides instant connectivity to RS-232 communication devices for factory automation equipment, multi-drop data collection devices, bar code readers, time clocks, scales, data entry terminal and serial communication in harsh environment and is suitable for remote access applications requiring high speed RS-232 communication ports.

Optical Isolation and Surge Protection
Your computer is well protected, since the surges and spikes cannot cross the optical link. Each serial port is individually protected by surge protector to withstand electrostatic discharge and power surges up to 25KV ESD (Electro-Static Discharge_. Surge suppression on all signals prevent from damages caused by lightning or high voltage.
Surge protection happens by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse
