How do you interpret the output values of the status port of the NAII 76CL1 xPC Target Block in Simulink?

I am currently setting up a test rig which includes an xPC Target computer with an NAII 76CL1 VDT emulator card. I am having some difficulties getting the system to work and thought the output status port of the xPC Target NAII 76CL1 Simulink Block might be able to shed some light. But nowhere does it tell you how to interpret the values that the port produces.

My setup uses 2 D/L channels with channel 1 configured as a 3-wire VDT and channel 2 configured as a 2-wire VDT. The output status port output is as follows:

8; 12; 0;

Any help would be much appreciated.

Thanks,

I think I have figured some stuff out. It looks like each channel is assigned two bits. If both bits are set to '1' the channel is healthy. Of course the display output I was using was configured to show data in double format and therefore for two channels:

3 = channel 1 is healthy

12 = channel 2 is healthy

15 = both channels are healthy

For the above output [8; 12; 0]; this suggests neither channel have a healthy excitation and both channels have a healthy output based upon the excitation. Of course this is 0V because there is no excitation. I have yet to figure out exaclty to what the '8' refers but it would suggest the internal test has failed completely on channel 1 and partially passed on channel 2:

 Ch2     Ch1
8   4 ¦ 2   1
1   0 ¦ 0   0
