Summary
With this professional 4port RS232 to USB-C FTDI chip adapter with RX and TX Status
LEDs you can easily add 4standard serial ports to your desktop, laptop or other mobile
device. This device also oers protection against static electricity, high voltage spikes and
other dangerous electrical shocks which can damage your equipment or data signaling.
The GM-FTDI4XC-LED 4Port RS-232 USB-C to Serial Adapter is compatible with most
GPS and PDA devices such as Garmin, Magellan, and Palm. Office equipment such as
modems, printers, scanners, and digital cameras are also compatible. With protection
against static electricity and surges up to 15KV, the Professional 4 Port RS232 USB-C to
Serial converter cable gives you reliable data transfers and protects the converter and
your equipment from damage due to over voltages.
The USB-C Plug and Play feature allows easy installation and requires no configuration
for IRQ, DMA, or I/O port resources. Just like most of our other converters, this adapter
is using the high quality FTDI chip which makes it fully compatible with all versions of
Windows, Linux, and Mac.
