4.3 Connecting to the Dispenser
4.3.1 Check the Communication Settings
1. Click the Ultimus V Configuration tab and select COMM from the list on the left side.
The installed COM port number (COM17 in this example) is shown on the right side. This list refreshes every
time you navigate to this setting. If you do not see your COM port, ensure that the COM port cable is properly
connected, change to the Current Settings tab, then return to the Comm tab, If the COM port still does not
appear, check that the COM port appears in the device manager and that it is not in use by another program.
Below the Select COM Port area is the Select Baud Rate (Data Rate) setting. Ensure that this settings matches
the baud rate setting of the Ultimus V dispenser. When you check the baud rate setting for the dispenser, EFD
recommends also ensuring that the expected front/rear connection is selected. Refer to “Communications Port
Options Screen” on page 26 for more details.
2. If you changed the baud rate to any setting other than the default setting (115200), click APPLY.
