Broadcasting the Service Message
The Service Message allows a device on the E-Bus to be positively identified. The Service Message contains the device ID
number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building.
There are two methods of broadcasting the Service Message from an Excel 10 W7761A Device. One uses a hardware service
pin button on the side of the device (see Fig. 24). The other involves using the PC Configuration tool, as follows.
The commissioning tool is used to perform the ID Assignment task (see the E-Vision User’s Guide form, 74-2588).
