To attach I/O expanders
To add inputs or outputs to the TV-PSM, you can attach up to 9 TruVu
XPIO expanders, but no more than 9 expanders total. Each expander must have a unique address (1 through 9)
set on its rotary switch. An MPC Open XPIO expander's address must be in the range from 1 to 6.

TruVu MPC I/O expander configurations
The expanders' outputs return to their unconfigured state if they are removed from the program or the program is
deleted from the controller. Also, outputs time out and return to their unconfigured or off state after two minutes
of inactivity. The unconfigured state results in:
•
Not running control programs that are due to download
•
Losing power to the controller, but not the expander
NOTE This does not apply to outputs that have been locked in the i-Vu® application.
