4 Hardware Configuration
The hardware of VScom USB-COM PRO is not configured via Jumper blocks or DIP switches, as
is mentioned above. Instead this is done by software. Each model has a single button named as
“Config”. User press this button for at least 3 seconds, a blue LED inside the button will light. This
shows the device is in configuration mode now. In configuration mode the serial port number 1 is
disabled, the configuration is done via the Com Port associated with this serial port. Pressing the
“Config” button again returns to normal operation, thus exiting from configuration mode.
This way of software configuration of course requires to have a driver for USB Virtual Serial Ports
on the system. That is not a problem, because without such driver the VScom USB-COM PRO
can not be used anyway. The configuration parameters are saved to a non-volatile memory inside
the USB-COM PRO, so configuration and use may happen on different systems.
4.1 Configuration via Windows Software
If the drivers for Windows are not installed, please do that now (chapter
3
). Then locate the
program UsbComCfg.exe on your CD-ROM, or in the files downloaded from the FTP server. Close
any application currently operating via the serial port(s) provided by your USB-COM PRO. During
configuration the first (or only) serial port is disconnected from the external devices.
On your USB-COM PRO press the button named “Config” for at least 3 seconds, a LED in the
button will light in blue color. The USB-COM PRO is in configuration mode now. Then start the
UsbComCfg program, it searches and detects all USB-COM PRO in configuration mode.
