Noob question. Injection pulses gone. Problem solved.

MS1 PCB v3.0 B&G base code yet. MegaStim v. 2.21.

Just got my MS1 assembled and proceeded to Stim testing. Everything was fine, there were normal reactions on pots. Pump switching on/off, idle enrichment indication, I1 and I2 blinking. After I failed to establish connection with PC, everything went wrong. Now I have PMP led blinking, no injection pulses and idle enrichment leds on Stim and on MS1 do not correspond, one may be lit on MS, while not lighting on Stim. Still cannot manage to establish connection with MegaTune, while Port Check utility find a valid port.

Tried to use Search function, but still need assistance.What should I check first?
Sorry for my English.

Hi, what cable are you using DB9 or USB, Regards DM

I'm using DB9 cable with Prolific USB-Serial adapter.

I'm using DB9 cable with Prolific USB-Serial adapter.

Hi, first have you loaded the driver disk that came with your USB adaptor, so if yes, then all you should have to do is select the correct COM Port, so under comunications select settings and baud rate 9600, timer interval 50, and the start with COM 1 and test, then 2 and so on until succesful, I hope that helps, Regards DM

Thank you for response. Problem is settled by replacing dead USB-Serial adapter with proper one.
