Figure 6. UVM connection process
You can configure actuated Venturi air valves with a factory mounted UVM1000 to meet a wide variety of application parameters. A USB to DB9 cable forms an RS485 connection between the air valve and the UVM configuration tool software. You can download the UVM configuration software from the Licensing Portal. For more information, contact your sales representative.
