How to connect the R-PO7470 to a PC through USB

Before physically connecting the R-PO7470 to the PC through the USB cable, you first have to install
the FTDI's virtual com port (VCP) driver. This driver is included in the R-PO7470 CD, or can be
downloaded from the following link:
http://www.ftdichip.com/Drivers/VCP.htm
An installation guide is also available at the following link:

Once the driver is installed and the R-PO7470 is connected to the PC through the USB cable you can
open a new HyperTerminal (for Windows) session.
In the R-PO7470's CD you can find a pre-programmed HyperTerminal session: copy it to the desktop
(or where you prefer) and run it. If you do not have the CD with pre-programmed HyperTerminal
session follow the next description.
To open a new HyperTerminal session, select the Start menu, then Programs, then Accessories, then
Communication and then lunch HyperTerminal. A dialog box appears, input a session name, (i.e. R-
PO7470), then press the ok button. Select the COM port assigned to the VCP driver (usually COM2).
Input the corresponding BAUD rate: check in the R-PO7470 menu, under set-up menu, which BAUD
rate is selected (default is 115200). Select the following options: data bits= 8, parity= none, stop bits=
1, Flow control=none. Press the ok button. At this point the connection starts, but the configuration is
not finished yet: stop the communication by selecting disconnect under the menu Call, then select
Properties under the menu File. A dialog box appears: select the Settings tab and press the ASCII
Setup button. A dialog box appears: select the Echo Typed Characters Locally features. Close the two
dialog box by pressing the ok button.
Now the HyperTerminal session is ready to start: select Call under the menu Call.
