Thanks a lot Eriks,
I did as you advised and the unit is working fine now. I was able to download unto the MRCAUDIO88 and the keypads are also responding well.
I really appreciate your advice.
One more thing before I go,youasked about the keypad spliting i did. There are more then 8 zones in the house. But, because of the limitations we had, i had to limit the zones to 8. The house was already prewired. I used 4 zones splitters to join the remaining zones. Can this lead to problems in the future?.
I follwed all the instructions in the manual in setting the address jumpers.
Please advise me .
