Do not use the ground lug onthe XLR connector. Do not connect the cable’s shield conductor to the ground lug or allow the shield conductorto come in contact with the XLR’s outer casing. Grounding the shield could cause a short circuit and erraticbehavior.XLR Pin ConfigurationPin1 = GroundPin2 = Data Compliment (negative)Pin3 = Data True (positive)Figure 3Special Note: Line Termination. When longer runs of cable are used, you may need to use a terminator onthe last unit to avoid erratic behavior. A terminator is a 110-120 ohm 1/4 watt resistor which is connectedbetween pins 2 and 3 of a male XLR connector (DATA + and DATA -). This unit is inserted in the female XLRconnector of the last unit in your daisy chain to terminate the line. Using a cable terminator (ADJ part numberZ-DMX/T) will decrease the possibilities of erratic behavior.Termination reduces signal errors and avoids signaltransmission problems and interference.It is always advisable to connect a DMX terminal,(Resistance120 Ohm 1/4 W) between PIN 2 (DMX-) and PIN 3(DMX +) of the last fixture. Figure 45-Pin XLR DMX Connectors. Some manufactures use 5-pin DMX-512 data cables for DATA transmission inplace of 3-pin. 5-pin DMX fixtures may be implemented in a 3-pin DMX line. When inserting standard 5-pindata cables in to a 3-pin line a cable adaptor must be used, these adaptors are readily available at mostelectric stores.
