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.

tact)-type output is connectable.
