problems with comms

Post by tsoldrin »

evening guys
I have been building up my bike for a while now i have finally got up to fitting the MS but after doing all the wiring and testing out the MS i have hit a dead end ... i have got comms problems. At first i had no problems with MT connecting to the MS but after playing around with the settings and trying to understand how to update the ini files i noticed my battery was getting a little flat so i packed up for the night and put my bike batt on charge to continue the work following day. this is where the problems started since this point i haven't been able to get any comms with the MS, so i will list everything that i think may be of any relevance

im connecting to the MS via a serial cable into a desktop pc (running XP) serial port
the bike wasn't moved or touched between the comms being successful and unsuccessful
i have reinstalled MT and all of the programs on the pc
when i try to port checker it runs through the the ports and baud rates, says "no connection" "one valid port"
when i tried to update the firmware on MS i get a timeout message and an error code 0xe0
when i turn the bike on and press the starter you can hear the fuel pump running
with MT running if i turn the ignition on the bike i get a flash of the gauges connecting, a beep from the pc and the low batt red warning turns to batt ok green just for a second and then goes back to low batt

i have gone through the comms troubleshooting guide as mentioned on other posts and i cant find any probs with the wiring, power or ground connections and now i am stuck as to what to do next

oh and i have checked the serial cable is plugged in properly and that the battery has charged on the bike

im looking forward to your suggestions as i cant wait to start up my bike

Is there any chance the serial cable itself may be damaged?

i dont think there could be any way it could have got damaged as i didn't even move the bike or pc ... just unplugged the serial cable from the bike and put the bike on charge

you can see in this picture where the bike stays and im working on the pc (the garage got a tidy up after the photo was taken!)
