My understanding is that the GX4816 with a DX168 shows SLink channels 1-48 for the GX4816 and 65-80 for the DX168 because of the blocks of space taken by each port. It would be great if this could be cleaned up. 1) to not waste the remaining 16 channels from the GX4816 block of inputs and 2) to allow more numerical flow of stage box inputs for installs.
