I'm trying to make my Stratix II (EP2S60F1020C4) communicate with the
Miniceptor (WJ-8607A) through RS-232.
I am able to communicate with the Miniceptor from the computer using
Hyper Terminal without a problem, communication between the FPGA and the
computer is absolutely fine, but the FPGA and the Miniceptor cannot
communicate properly between themselves. I have tried to send commands
from the FPGA to the computer, and I receive exactly what I am supposed
to. I've also send words directly from the computer to the Miniceptor
and the chip receives commands without fault. But when I send the same
words from the FPGA directly to the Miniceptor, the Miniceptor does not
recognize the sent commands.
I've already made sure the voltage levels of the signals match
specifications on both sides, and I've analyzed the sent words using a
logic analyzer. Everything appears to be in order, I'm sending what I
should be, but the Miniceptor just won't recognize it.
Any suggestions! Time is of the essence, any help is appreciated.
