DATA TERMINATION
It is always recommended that daisy chains be terminated with a resistor of the same
characteristic impedance as the cable (typically 100-120 Ohms will be sufficient). To terminate a
daisy chain, place the resistor across RJ-45 pins 1 and 2 as shown in Figure 20.

Master/Slave Operation
The FiberLamp is able to act as a DMX master or slave in a DMX network, depending on its DMX
Mode settings.
DMX MASTER OPERATION
When in DMX master mode, the FiberLamp sends DMX commands to all other fixtures in the
same DMX network. The commands from the FiberLamp in DMX master mode include
information about what it is currently executing. Because DMX slaves only execute commands
sent to them, the slaves will execute exactly what the DMX master is executing.
Note: When in
DMX master mode, the FiberLamp will not receive any incoming DMX commands.
Follow the “DMX Mode” setting procedure in section 4 to set the FiberLamp to DMX master
DMX SLAVE OPERATION
When in DMX slave mode, the FiberLamp receives and executes DMX commands from a DMX
network.
To ensure that the FiberLamp responds properly to DMX commands, make sure the unit is
configured to be in DMX slave mode and set to the correct DMX address. After the FiberLamp
has been properly installed at the desired physical location, connect to power, and connect to the
DMX network. Verify that the DMX controller for the network is sending the correct commands,
the signal strength is adequate and that the FiberLamp is responding accordingly.
