■Time Adjustment with an External Equipment

The specified external devices can output the time adjust- ing signal to the matrix switcher.

This signal can adjust the time by up to ± 30 seconds every hour.

To use this function, it is necessary to assign one of the alarm input terminals (pin # 1 to 16) to the time adjusting terminal.

SETUP MENU or WJ-SX150 Administrator Console can assign the signal.

The figure below shows the case in which Alarm Input 16 is assigned as the time adjusting terminal.
