QJ71C24N-R2 RS232 Read help

2 posts in this topic

I have a QJ71C24N-R2 card with a mitsubishi Q-Series PLC. I am having trouble reading Ascii that is being sent to the card. I have an X3 bit that should be turning on that isn't. I can see the strings sent in the card's buffer, in its 600h registers. the device sending the strings sends a CR, or 0Dh as a terminator. Any help? Thanks

what is the base address of the card? if this is not first card in the rack, it most likely is not using base address 0h and therefore all signals need to be offset. so your "X3" may actually be X13 or X43 etc. what are the card settings? does it expect CRLF as terminator?
