HI all,
In my application board there was an converter called
CONV485-DB9 which converts rs232 data in to rs485 which is an DB9
connector at both ends.Can anyone help me to checkout the converter
whether it is working properly or not.
I had given the RS232 female end to my serial COM port and the
other end of the RS485 male connector was given to my application
board,which contains an RS485 Half duplex tranceiver.I have utilized
only 3 pins namely 2,3,5 of the RS485 connector.These signals were
given to my transceivers differntial voltage pins A and B.Does these
signals are sufficient for transmitting the data.
When i am trying to detect the baudrate of my Dsp
controller,it was getting failed.My Host PC will send some data and
receives the data from the controller.
At the time of testing my RS232 port through accesing some
software,i am able to see some data that was transmitting through the
2(tx) and 3(rx) pins of rs232 port,whereas when i am trying to see the
same data at the other end of my converter which is at the RS485 port
side,i am not able to see any voltage,Does my converter fails or else
is there anything wrong with the half duplex.Atleast i should see some
data at the rs485 port side pins.I am having two such converters,both
of them were giving the same problem.
Please give me your suggestions to solve my problem.
With Best Regards,
Sudheervemana.
