ADJ Products, LLC - www.adj.com - Focus Beam LED User Manual Page 10Special Note: Line Termination. When longer runs of cable are used, you may need to use a termina-tor on the last unit to avoid erratic behavior. A terminator is a 110-120 ohm 1/4 watt resistor which isconnected between pins 2 and 3 of a male XLR connector (DATA + and DATA -). This unit is insertedin the female XLR connector of the last unit in your daisy chain to terminate the line. Using a cableterminator (ADJ part number Z-DMX/T) will decrease the possibilities of erratic behavior.Focus Beam LED DMX Set UpDMX512 IN3-PIN XLRPOWER POWER123Termination reduces signal e rrors andavoids signal transmission problemsand interference. It is always advisableto connect a DMX terminal, (Resistance120 Ohm 1/4 W) between PIN 2 (DMX-)and PIN 3 (DMX +) of the last fixture.123Figure 45-Pin XLR DMX Connectors. Some manufactures use 5-pin DMX-512 data cables for DATA transmis-sion in place of 3-pin. 5-pin DMX fixtures may be implemented in a 3-pin DMX line. When insertingstandard 5-pin data cables in to a 3-pin line a cable adaptor must be used, these adaptors are readilyavailable at most electric stores.
