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 the alarm
input terminal(s) (pin # 1 to 16) to the time adjusting termi-
nal(s).
SETUP MENU or WJ-SX150A Administrator Console can
assign the signal.
Note: In the master-slave connection, time setting of every
unit can be synchronized when the time adjusting sig-
nal is input to any unit.
Master Clock Connection Example
for Time Adjustment
Connect the matrix switcher's time adjusting terminal to
those of the master clock with the twisted pair cable.
The figure below shows the case in which Alarm Input 16 is
assigned as the time adjusting terminal.
Note: A master clock with N.O. (Normally Open alarm con-
tact)-type output is connectable.
