I bought 1784-ktcx15 from e-bay to be able to program logix5000 processor by connecting the module to 1756-cnb. The unit came without any software.but I do have RSLINX on my computer. After I installed the unit in my computer (window 98 OP. SYS) my computer didn't regognize the card. when I list all the hardware my computer didn't list the 1784-ktcx15. What I should do. Thank you
