Other Parts Discussed in Thread: SN75176B,
Hi,
I'm using two RS485 transceivers to communicate between two controller cards.
Below are the two different part no's
SN75176B
SN65HVD1473
SN75176B part works under 5 volt supply and SN65HVD1473 works under 3.3 volt supply.
I'm trying to send/receive data between two controller card using these two Transceivers.I have probed single ended signal and taken screen shoots.
The prob 4 shows the data transmitted from the controller 2 and and Probe 2 shows the data received at controller 1.
I have noticed that the transmitted data from the Controller 2 is not exactly received at controller 1(controller 1 is in Receive mode)
But Data sent from controller 1 is received properly at controller 2(Controller 1 is in Transmission Mode) .For clear details please refer the attached document.
Please can any one suggest what could be the reason for this issue.
Regards
Ashok
