2.2.56. Manufacturer Proprietary Command Class, version 1 [OBSOLETED]

Warning

THIS COMMAND CLASS HAS BEEN OBSOLETED

New implementations MUST NOT support this Command Class. Consult the Z-Wave Alliance when your application does not seem to fit any existing Command Class.

The Manufacturer Proprietary Command Class is used to transfer data between devices in the Z-Wave network. The data content MUST be vendor specific and MUST be non-value added with respect to the Home Automation application in general. An example could be data used to diagnose the hardware in a device.

Note: Do not use the Manufacturer Proprietary Command Class without written approval from the Z-Wave Alliance.

2.2.56.1. Manufacturer Proprietary Command

This command is used to transfer proprietary commands between devices. The Command features a manufacturer specific identifier to allow the receiving device to check if this Command can be interpreted. The vendor is responsible for establishing a Command structure to differ between the set of Commands supported.

In order not to congest the Z-Wave network, large data transfers MUST leave transmit opportunities for other nodes in the network. If sending a command longer than two frames, a node MUST implement a delay between every transmitted frame. The minimum required time delay and number of frames before a delay must be inserted depends on the actual bit rate.

  • 40 kbit/s: At least 35 ms if sending more than 2 frames back-to-back

  • 100 kbit/s: At least 15 ms if sending more than 2 frames back-to-back
