RS-232 Pinout and Baudrate Settings
The RS-232 port on the HD800V2 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 HD800V2 can also be used with USB to RS-232 conversion cables, 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.)
The RS-232 port is a female type DE-9 connector (sometimes mistakenly referred to as a DB-9 con-
nector) with the following pinout:

1 - No Connect
6 - No Connect
2 - TX
7 - No Connect
3 - RX
