The field terminations used in Unison are easy to remember and identify. All low voltage connections are keyed, pluggable, on standard 5mm spacing and made by a variety of manufactures. To differentiate between the different connections, different sizes are used. There are 5 different sizes, 3pin (DMX-In), 6pin (DMX-I/O), 8 pin (AUX. Power DC), 10 pin (LinkPower) and 12 pin (0-10V fluorescent). After wiring a terminal block be sure to replace it in it's matching socket.
