Here is a 4-port USB to RS232 converter which can be used as a desktop converter but it also has brackets included for wall and DIN installation. The enclosure is made of metal and it has 15KV ESD protection against static electricity and voltage surges, so it is an ideal solution for most applications including office, commercial, laboratory and even light industrial environments.
All four RS232 serial ports can be used individually since the drivers and operating system will assign four unique serial COM ports for the converter. Each port can send and receive data without interference from the other port.
Drivers are downloadable for free from our website and easily installed by clicking an auto-installer file. The drivers will create four virtual COM ports which will show up in your operating system's Device Manager.
This USB to serial RS232 converter is powered through the USB port, however external 5VDC can be applied through a standard barrel connector if your application draws additional amperage or if you are connecting through a USB hub which doesn't provide sufficient power.
LED indication lights indicates when data is sent and received and when the converter is powered on.
The converter is built around the high-performance and reliable FT4232HL chipset from FTDI Semiconductors which makes it fully compatible with most operating systems, including Windows, Linux and Mac (32/64-bit).
