Advertise the BC840-MC
On the Auto Discovery tab, you can enable UPnP (Universal Plug and Play). If enabled, UPnP
allows the BC840-MC to advertise its presence and services to control points on the network.
A control point can be a network device with embedded UPnP, a VMS application or a spy
software tool, such as Device Spy. With the UPnP service enabled in Windows (see Appendix:
Enable UPnP in Windows 7), you can connect to the BC840-MC from Windows Explorer.

Note
Note on UPnP: The goal of Universal Plug and Play (UPnP), a set of computer network
protocols, is to enable peer-to-peer simple and robust connectivity among stand-alone
devices and PCs from different vendors. UPnP networking involves (some or all of) the
following steps.
Step 1: Discovery. Devices advertise their presence and services to a control point on the
network. Control points can search for devices on the network. A discovery message is
exchanged, containing a few essential specifics about the devices, e.g. its type, identifier and
a pointer to more detailed information.
Step 2: Description. The control point can request the device's description from the URL
provided in the discovery message. The device description is expressed in XML and includes
vendor-specific information, such as the model name, serial number, manufacturer name,
URLs to vendor-specific web sites.
Step 3: Control. The control point can send actions to a device's service.
Step 4: Event. The control point listens to state changes in the devices.
Step 5: Presentation. If a device has a URL for presentation, the control point can display a
page in a web browser, and – if the page offers these capabilities - allow the user to control
the device and/or view the device status.
The BC840-MC supports the following Universal Plug and Play (UPnP) functionality: Discovery,
Description (partly supported), and Presentation.
