Depending on your power supply, TruVu™ MPC I/O expanders can be w ired for communication to the TV-
MPCXP1628-NR's I/O Bus port, with AC or DC power supplied separately, or directly-connected to the TV-
MPCXP1628-NR's I/O bus edge connector (DC only). The type of power, AC or DC, requires different device and
power arrangements. See TruVu™ MPC I/O expander configurations (page 9).
Each expander must have a unique address (1 through 9) set on its rotary switch. See the TruVu™ MPC I/O
Installation and Start-up Guide for more details.
To wire the TruVu ™ MPC I/O expander to the I/O Bus port to ena ble communication (AC or DC)
Use ARC156 wiring (22 AWG, low-capacitance, twisted , stranded, shielded copper wire) to wire the TruVu™ MPC
I/O expander to the controller. Do not exceed 1000 feet (305m) total wire length for the I/O bus.
WARNING Do not apply line voltage (mains voltage) to the expander's ports and terminals.
1
Turn off the controller's and expander's power.
2
Wire the expander's I/O Bus port to the same port on the controller.
NOTES
○
To use more than one expander, wire their I/O Bus ports together in a daisy-chain configuration. The
controller must be the first device on the expander network.
○
Use the same polarity throughout the network segment.
3
On the last expander on the I/O bus, set the I/O Bus End of Net? switch to Yes to apply network termination
and bias.
NOTES
