Special Note: Line Termination. When longer runs of cable are used, you
may need to use a terminator on the last unit to avoid erratic behavior. A
terminator is a 110-120 ohm 1/4 watt resistor which is connected between
pins 2 and 3 of a male XLR connector (DATA + and DATA -). This unit is
inserted in the female XLR connector of the last unit in your daisy chain to
terminate the line. Using a cable terminator (AZTEC part number DMX/T)
will decrease the possibilities of erratic behavior.
5-Pin XLR DMX Connectors. Some manufactures use 5-pin DMX-512
data cables for DATA transmission in place of 3-pin. 5-pin DMX fixtures may
be implemented in a 3-pin DMX line. When inserting standard 5-pin data
cables in to a 3-pin line a cable adaptor must be used, these adaptors are
readily available at most electric stores. The chart below details a proper
cable conversion.
