Power Up Display
When the power switch of the Matrix Switcher is turned on, a screen similar to the one shown below is displayed on all moni-
tors.
There are three slightly different displays possible: Cold Start, Normal Start and Hot Start.
The Cold Start is the initial display seen when the Matrix Switcher is turned on for the first time. The Normal Start is displayed if
the system has been shut off for two consecutive midnights (for example: the system is turned off Monday at 11:00 P.M. and
turned on Wednesday at 1:00 A.M., for a total of 26 hours off). The differences between Normal and Hot Starts are as follows:
1) With a Normal Start the ROM version numbers are displayed while in the Hot Start they are not (ROM=Read Only Memory).
2) With a Normal Start the monitor screens will be blank, but with a Hot Start whatever monitor/camera combinations were
displayed at power off will be displayed again (like a Resume function).
3) If the power is turned on with a Normal Start during a Timer Event, the Timer Event will not occur. However, if the power is
turned on with a Hot Start during a Timer Event, the Timer Event will occur.
Caution: If the WJ-AD550 Extension Unit is used in the system, turn the Extension Unit power on before turning on the power
of the WJ-SX550B Matrix Switcher.
