Hello you all , Woundrring if any of you have had anyluck communicating with the newer style latch board. The LED light flashes red then green over and over. I added terra term to my pc. I am hooked up to the DP9 rs232 port on the borad. My buad rate 19200, 8 bit and 2 stop bits are all correct. Com port is set. But still not communicating. I was told by Marathon that they dont recomend linking up and just told me that blinking red means an input is grounded. Ok thats go to know i will ohm them out to find which one or ones. I still would like to get into the diagnostic i thre latch board itself. The paper i have with latch board tells me i should be able to.
