To support legacy instruments which do not report serial number information over the interface,
ProCal provides the ability to set a 'static' FTDI address.
How to configure a static FTDI address :
1. Determine the FTDI address of the instrument by connecting the instrument using an FTDI Usb to RS232 converter lead as
described in this solution :
2. Determine the UNIQUE FTDI ADDRESS - this is displayed on startup of ProCal and can also be re-displayed by selecting :
The FTDI address is displayed in SQUARE BRACKETS - see the EXAMPLE below :
Note : Your device ID will be a UNIQUE number displayed by your specific computer :
Note : The FTDI address is unique to a specific lead (or instrument if the USB interface is built-in) -
the square brackets are NOT part of the address and should be omitted, eg. :
3. Use ProSet to enter the static FTDI address for the required instrument :
ProCal will now use the specified FTDI static address to communicate with the instrument as configured in ProSet.
