DMX512/RDM connections
« on: May 25, 2011, 04:04:28 PM »
I am sorry about this basic question but I can't get the answer from searching on the web.

DMX and RDM equipment have In and OUT connectors/ports, how are they connected internally? Are the relevant pins of the connectors daisy chained i.e. PORTIN +ve is connected to PORTOUT +ve and this is then connected to +data output of the transceiver? Or is each connector/port connected to its own RS485 transceiver?

Will the connectors for RDM equipment be connected internally the same way as that for DMX?

I am sorry I just can't visualize the connections from the specifications of DMX and RDM.

Hope you can help. Thanks.

Hi, electrically, a DMX512 device (other than the console) is wired the same as it always was, so the input and output sockets are connected together pin for pin, and the transceiver chip connected to the sockets.
