Port Status:
The letters appearing below the Port indicate the port’s
customization. Many combinations are possible; the examples are
generic for clarity.
The letter “I”: Indicates the port is sourced from the primary input
“DMX IN” and that RDM is enabled.
Letters “A” through “H”: Indicates the port is in Hub mode and is
sourcing its signal from the indicated port. Although several ports
may be customized to act as possible inputs, only the letter of the
port active as an input will be shown.
The letter “M”: Indicates the port is in “Filter/Merge” mode and RDM
is disabled. If all ports are labeled with “M”, the box is acting as a
simple 8-port DMX opto-splitter.
In this example, the Repeater is in DMX Merge mode, and port A is
active as a secondary input, being merged with the normal “DMX IN”
source.
The “-”: Indicates the port is in Hub Mode, but there is no signal at
any input port.
The “X”: Indicates the port is disabled.
