5.2.4 Communication Interface and Protocol
The PDS-C4 appears as a virtual serial port (also called a UART or VCP). On Microsoft Windows™,
the system will appear as a COM port, the COM
port number can be found in device manager.
On macOS®, a device file is created in the / directory. S is an alpha-numeric serial string unique
to each device
/dev/tty.usbserial S
Devices incorporate a FT230X USB to UART converter IC from FTDI International. On Windows 7
or later, a driver may automatically be installed (if Windows is configured to download drivers
from the internet automatically). If this is not the case, or if a Mac® or Linux® platform is used,
the driver may be downloaded from www.ftdichip.com. The VCP drivers are required. For Linux®
or Mac computers, the default OS drivers should be used.
The default communications settings should be set to 115200 baud, 8 data bits, no parity, and
one stop bit. This is sometimes referred to as "115200,8,N,1". No flow control is used. ANSI
terminal emulation should be selected
