Config Request Message

Config Request Message is sent by a device to request configuration data from a remote server or other device.

=Contents= The message first has a DCP Header. After the header the contents are:

Fields:
 * DeviceType: the type of device; must match server
 * Device SubType: in case the same device type is requesting multiple configurations
 * Firmware Version: the firmware version of the device, so that the server can be sure to respond with only the parameters that are supported.
 * Reserved: reserved for future use. In COIL and other implementations, disregard the value as it is not guaranteed to be any particular value.
