Welcome to the SR5002-Control wiki!

Objective

The objective of this set of programs is to provide network control of the Marantz SR5002 AV Amplifier. The SR5002 can be connected to a relatively low powered computer such as a Raspebrry Pi thus enabling it to be controlled from a number of other computers such as MythTV frontends to which the SR5002 is connected via HDMI. The SR5002 can be independently controlled to determine which of its 3 HDMI connections is to used as its input HDMI channel. Each MythTV frontend sending the appropriate commands to the SR5002 to configure it so as to use the HDMI input channel to which the frontend is connected. It should be noted that if a RasPi is used then a USB to RS232 converter has to be used since the RasPi does not have an RS232 connection.

Method

The programs comprise of:

  • an interface program that is called to send commands to the SR5002. The commands are supplied as a parameter string of space separated SR5002 commands
  • a client program which receives the commands from the interface program
  • a server program which receives commands from the client program via a network connection
  • a configuration file which is used to control/configure the three programs above. The SR5002 is normally connected to the server host computer via its RS232 connection.
