Bob,
I believe the problem may lie with the initialisation .
The SUSIC is set up with 24 bit cards in the following format:-
OOOO OOII IIII
My interpretation of the initialisation sequenece is ua=0, Type= N, NS=3, CT = aa 5a 55
I have checked via the CMRI monitor for this sequence and have found that for 4.6, 4.7.4 & 4.8 the sequence is ua=0, Type=N, NS=16, DL=10, CT= 3 aa 5a 55 ????? I would have expected NS to be 3. It appears to have added the correct NS to the CT sequence. The baud rate on the SUSIC matches the preferences entry and there is only one entry for the CMRI.
I should have been clearer on the fast flash - this is not the amber and red send/rec LED's but the Green which should indicate a slow flash if the SUSIC is successfully initialised. I get the slow flash for 4.6 but once upgraded to 4.8, I get the fast flash.
Under 4.6 I can use the CMRI diagnostics on one output card located in slot 0 and can see the successfull result of the test sequence. 4.7.4 & 4.8 as mentioned won't initialise even for just one output card.
For all three versions I tested, I get ua=0, Type=N, NS=1, CT = x for output cards in slots 0 to 3. As soon as I add a 5th card as a second card set, it appears to add the NS as the first digit for the CT sequence followe by the correct CT numbers.
Short of removing all traces of Java and JMRI from my laptop and reinstalling, I'm not quite sure of any other diagnostics I can try. In the longer term, I am planning to replace my laptop so perhaps if it is driver related, that may help.
