Option 36: Four Configurable Outputs
C.16.1
General Description
Option 36 adds four rear-panel outputs, which may be configured to any available signal in the
1093A/B/C series clocks. Note that there are many more jumper settings on the Option 36 board
than the 1093A/B/C is capable of providing. The configuration of the four outputs can be changed
at any time via internal jumper settings.

Case Removal
To change the configuration of Option 36, the top cover of the instrument must be removed. Turn
off the instrument, and disconnect the power cord. Using a T-25 Torx driver, remove the four
screws holding the cover (and rack mount ears, if used) in place, and lift the cover off.
WARNING
Do not remove the top cover while power is applied. Hazardous voltages are present
while the power cord is connected. Always disconnect the unit from the input power source before
removal of the top cover.
