A DSP Frame is the central component of each RM4200D. It is either used stand-alone (e.g. as a signal router) or connected via CAN-Bus to one or more Control modules. Each RM4200D system contains one single DSP frame.

Several RM4200D systems can be operated together. A typical setup would include several studios which are interconnected using a central router. In such an application, the RM4200D in the studios have control Consoles, whereas the router system has no Console. The studio DSP frames are connected to the central router using MADI and Ethernet to exchange audio and control signals.

	Important
	Any DSP frame can be connected to one CAN bus only! It is therefore not possible to operate more than one DSP frame on the same CAN bus!

Setting up the software

The Toolbox4 software is a normal Windows program. It does not require any additional DLLs or other files. For installation, copy the program file on to the hard drive of your PC. To remove the program, just delete its program file. Start the software by opening the file Toolbox4.exe.

You can use the software without the RM4200D hardware, e.g. to change or check configurations “offline”. However, in most cases the configuration PC is connected to the RM4200D  – either using TCP/IP over Ethernet or a direct serial connection.

	Note
	Using Ethernet to connect the Toolbox4 software to the RM4200D is faster and more convenient, but it requires the correct configuration of the IP addresses. (see Configuration of IP Addresses)
