That makes sense. I looked at the data sheets, but they are mostly greek to me. So to make a cable using the SN75176B for example, would I just solder the link cable's tip line to pin 1 of the transceiver, the ring to pin 8, line A of the DMX cable to pin 6, and line B to pin 7? That's what I gather from the transceiver in this diagram:
![]()
Here's another one:
![]()
From what I can tell, the ring needs to be connected to pin 8 to provide the +5V to the transceiver. It would just need to be high the whole time and the tip would provide the data by itself by going high and low. Are these conclusions correct? Also, the calculator itself shouldn't receive any data from the DMX, but the transceiver is probably necessary to prevent the link port from getting accidentally fried.
