As shipped from the factory, DFI instruments are set to communicate at address 00.
To determine what address the instrument is using from the front panel:
1) Enter the setup menus by pressing [UP] and [DOWN] together. The display will read
"
SETUP " and then " CHANNEL 01 MENU " (which is the top-most item on the setup menus).
2) Press and release [DOWN] until the display reads " SERIAL COM. MENU ". Press
[ENTER] to enter the SERIAL COM. menu.
3) Press and release [DOWN] until the display reads "
ADDRESS ".
Press [ENTER] and the display will show the address. The address cannot be changed
from the front panel, only from the serial port.
4) Press [EXIT] to exit the menus and restart the instrument.
