System Status
* A system is in IOS mode when an unexpected, temporary, critical error is trapped and logged and control is passed to the
host software (IOS) which prevents normal appcode from running until the error is manually cleared. Please report all such
errors to technical support (see page 69).

Offset amounts are entered in seconds (3600 seconds = 1 hour). For example, when setting Pacific Standard Time (PST)
in the US, the offset would be -28800 (-8 x 3600, the equivalent of eight hours off Greenwich mean time).

Slowly slide the CPU board into the empty slot, being careful to align the edges in the board guides along the
insides (the board guides are shown in FIG. 139).
Push on the CPU tab firmly enough to make a good electrical connection (avoid pushing on the connectors). When
fully inserted, the faceplate on the CPU should sit flush with the back metal.
Reattach the faceplate with the two screws that were removed in Step 3.
Plug in both AC power cords.
Check the CPU's System Status LED for indications of normal display (see table below).

Constant green during power up, then blinking
green at 1/2 second on/off intervals.
Re-attach the cables that were removed in Step 2.
Execute a test switch to be sure the system is working correctly (see page 56).
Use a null modem serial cable to connect a PC to the Control port (RS-232 serial) on the enclosure.
Open DGX Configuration Software – available at www.amx.com (or another terminal emulation program)
