The MTS GUI should be used for the standard configuration. The screenshot in Figure 4-2 shows an example of setting CobraNet™ bundle addresses, where the instruction sequence is “1” for an HMI (CobraNet™) command, “rxBundle” is the Bundle receiver command given in Cirrus Logic’s programmers manual (PM25) “2” represents the receiver number (Note: all HMI commands are “0” referenced, therefore receiver bundle 1 is address 0, bundle 2 is address 1, etc; so rxBundle 2 is actually Receiver Bundle 3). Figure 4-2 shows reading the value of Bundle 3 (rxBundle 2) as 666, then Bundle 3 is set to 111 and then reading the value confirms the setting as 111.

Similarly, Figure 4-3 below shows the setting of DSP parameters.

Figure 4-3: Setting CobraNet™ DSP parameters

The instruction sequence is “1” for an HMI (CobraNet™) command, “controlRWValue” is the DSP read/write command instruction “50” represents the DSP offset (see section 3.2.2 above) for router output channel 1 (see Figure 4-4 below). The Router output channel 1 (Offset 50) is initially read set at input channel 2 and is then set to input channel 0 (ie mute).
