Option 03: Four Additional Outputs –
Obsoleted by Opt36
C.4.1
General Description
Option 03 adds four rear-panel outputs, which may be configured to an available signals in the
1092A/B/C or 1093A/B/C series clocks. Note that there are many more jumper settings on the
Option 03 board than the 1092A/B/C or 1093A/B/C is capable of providing. The configuration
of the four outputs can be changed at any time via internal jumper settings.
C.4.2
Specifications
General
Output Connectors:

Also available on
clock Models 1088B, 1084A/B/C and 1093A/B/C
.
Changing Output Settings via Internal Settings
Case Removal
To change the configuration of Option 03, 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.
