RS-232 Connector Pins

On some HV-2000C models there is a serial port DB9P female connector located on the
front panel. This RS-232 port is used to connect the controller to a PC using a
USB-to-Serial Adapter cable. Connect the USB Plug end to the PC's USB port, and
connect the Serial DB9 plug to the RS-232 port.
For system configurations that are not using a USB Serial RS-232 cable, the following
table shows the correct RS-232 cable pin-outs when connecting directly from a PC
serial port:
