For the NK-2.4Y, why can I only transmit switching signals one way when the module is specified as having 2-way communication?
The 2-way feature of the NK-2.4Y modules is used to determine the link status between input and output module. It does this by continuous communication between the input and output modules allowing real time indication of the LINK status. So functionally for switching signal transmission, it is one way only.
