R450 Wall and Pit MIU User's Manual
If connecting the MIU to a new ProRead (ARB VI) encoder register, or if a three-
conductor cable is already connected to a ProRead (ARB VI) encoder register,
ensure that the ProRead (ARB VI) register is programed for three-wire mode using
the ProRead (ARB VI) programmer and its RF/MIU 6, 8, or 10ID TDI format. This
can be accomplished through the ProRead (ARB VI) receptacle before removing
the receptacle.
1 Before wiring the pit encoder register, make sure the cable is long enough.
Then, when the installation is complete, the pit lid can be removed easily with-
out straining the cable.
2 Use only 22 AWG cable to make the connection from the encoder register to
the MIU.
3 Remove the terminal screw cover from the encoder register.
4 Strip off 3/4" of jacket from the cable, leaving only the three insulated wires.
5 Taking precautions not to nick or cut the insulation on the three wires, strip off
1/2" of insulation from each of the three wires.
