Local access to the UPC Open — The user can use a BACview6 handheld keypad display unit or the Virtual BACview software as a local user interface to an Open control- ler. These items let the user access the controller network infor- mation. These are accessory items and do not come with the UPC Open controller.

The BACview6 unit connects to the local access port on the UPC Open controller. See Fig. F. The BACview software must

be running on a laptop computer that is connected to the local access port on the UPC Open controller. The laptop will re- quire an additional USB link cable for connection.

See the BACview Installation and User Guide for instruc- tions on connecting and using the BACview6 device.

To order a BACview6 Handheld (BV6H), consult Commer- cial Products i-Vu Open Control System Master Prices.
