Introduction

Proxies (Commands)

This documentation includes content that details the functions that make up the Media Player Proxy which is supported in the DriverWorks Software Development Kit.

A proxy driver is an interface to the Control4 system for a set of devices that share common functionality. For instance, most media players have common controls such as PLAY, STOP, PAUSE and SKIP. The media player proxy allows for a common user interface to control all media players. The Control4 system (Director) sends information to and receives information from the proxy drivers. The proxy drivers send information to and receives information from the protocol drivers. Remember, your DriverWorks driver interacts with the proxy driver which then interacts with the system. As a driver developer you will be relying on this proxy to provide status (notification) to the Control4 system for the device you are controlling. You will also receive commands from the system that you will act on to control the device. These commands and notifications are at the heart of what you will be implementing in your driver. Essentially your driver is becoming the go-between from the Control4 system and your device with the proxy driver giving structure to the commands and notifications which you will be implementing. Your driver can facilitate communications with multiple types of proxies for a single device. As an example, a Security System driver will utilize both the Security proxy and the Contacts proxy. These additional proxies are configured in the <connections> section of the .c4z.

Protocol (Notifications)

Two similar devices may have the same functionality but utilize a very different command set. A protocol driver provides the device-specific information needed to communicate with the Control4 system. In the case of DriverWorks, the DriverWorks driver is the protocol driver. When combined with the device-specific.c4Z file it provides the custom code necessary to implement the 2-way device driver. In the case of DriverWorks, the DriverWorks driver is the protocol driver. When combined with the device-specific.c4Z file it provides the custom code necessary to implement the 2-way device driver.

Audio Output Bindings and Proxy Events

Note: Audio Output binding ID values defined in drivers written in conjunction with this Proxy must start with a binding value of 4000. The acceptable range for Audio Outputs is 4000 - 4999. However, if the first output binding ID value is not 4000, issues with Proxy Events firing correctly can be encountered.

For a list of valid Binding ID values please see the Connections section of the DriverWorks Fundamentals Guide.
