Hi im having a problem with my MCB900 board. The program i am trying to run on it will not work correctly unless the board is connected to the pc via the serial connection. Is this a grounding issue and if so how do i fix it?
yes it is ground must connect on the pin. chek inputs and line to the negetive on the ov pin.
.. all equipment would come with a "free PC"
I am not posting this to berate mandar, I am fairly certain that the misinformation is due to a language problem; however to the OP: your MCB should run w/o the cable connected - see Pers post.
