RS-232 Pinout and Baudrate Settings
The RS-232 port on the ClarityAudio is the same format, and pinout, as a PC modem, and uses the
same type of cable as a standard serial modem would, which is a standard straight through cable. Do
not use a cable that is marked as a “Null Modem” cable.
The ClarityAudio can also be used with any USB to RS-232 conversion cable, these are all typically
straight through cables. (Be sure to install any drivers that come with the USB to RS-232 cable you are
using.)

nector) with the following pinout:
