Other Parts Discussed in Thread: MAX232
Hi,
I am using the TI development board. It was working fine few hours back until i tried connecting a different hardware to talk using UART port.
So the board is powered from the cells. I am simulating 14 cells using resistors. Input Voltage is 52V supply and 0.08 A current which creates 3.7 V of reading across each resistor. But as soon as i connect the USB to laptop ,the LED on the board turns green but the input voltgae drops down to 30V. I tried using different laptops but results were same. I am now not able to open the GUI provided by TI( error says cannto open COM port). I am thinking that maybe i blew up the board connecting a RS232 cable to the TI board( i was trying to mimic the TTL-UART connector provided by TI).
I wanted to know if there are any clamps on Rx and Tx of UART on TI board.
Also , is the board reparable considering this situation?
