16 Martin DMX 5.3 and RDM 5.5 Splitters user manual
Data connections and
setup
The Martin DMX 5.3 Splitter uses 3-pin XLR and the Martin RDM 5.5
Splitter uses 5-pin XLR sockets for all data connections: in, optically
isolated, optically isolated, thru and out.
Pins 4 and 5 in 5-pin XLR connectors are not used by DMX or RDM
signals, but if you intend to use pins 4 and 5 in the RDM 5.5 Splitter’s 5-pin
sockets for any other purpose, note that these pins are connected from
the in to the thru socket, but that there is no connection to pins 4 and 5 of
the out sockets.
Data input
Connect the data link cable from the controller to the in socket on the
Splitter using a female XLR cable connector.
Data throughput
The main data link daisy-chain can be continued at the thru socket using
a male XLR cable connector. The signal that is relayed from the in to the
thru socket is not amplified or processed in any way and is available even
if the Splitter is not powered.
DMX termination
The DMX termination button (see Figure 8) on the front of the Splitter must
be:
• pressed in to activate termination if you do not connect devices to the
thru socket, and
• not pressed in if you continue the data link from the thru socket.
