Use a DMX signal amplifier when the signal cable distance exceeds
60 meters (200 ft). Maximum recommended number of devices on a
serial data link is 32 devices.
A DMX terminator is recommended for installations where the DMX
cable has to run a long distance or is in an electrically noisy
environment (e.g. discos). The terminator prevents corruption of the
digital control signal by electrical noise. The DMX terminator is simply
an XLR plug with a 120 Ω resistor between pins 2 and 3, which is then
plugged into the XLR output socket of the last device in the chain.
