Changing Output Settings via Internal Jumpers
Case Removal
To change the configuration of Option 12, 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.
C.10.7
General Information
Option 12 incorporates an extremely flexible output selection system, which is made possible by the
same jumper scheme used in the main clock. Each of the four rear-panel BNC-type I/O connectors
included with Option 12 can be configured to perform any of the available output functions. Figure
1 shows the locations and functions for all of the jumpers on the Option 12 board.
Function Selection:
Jumpers JMP3 through JMP10 determine what output function their respective I/O connectors
perform. The dotted lines in Figure C.8 show the relationships between the jumper strips and the
connectors. Set the jumper for each connector to the appropriate location for the type of output
signal desired. The signals available are listed in the text to the left of the jumpers in Figure C.8.
Mode Selection:
In addition to specifying the output signal type for each individual connector, it is necessary to
define whether the signal is analog or digital. This is accomplished using jumpers JMP11, JMP12,
JMP14, and JMP15. Each of these jumpers corresponds to the output function jumper for one of
the output connectors; the relationships are illustrated by the dotted lines in Figure C.8. Table C.3
shows the Function and Mode jumper settings for all of the various output signal types. Only the
Modulated IRIG-B and Deviation outputs are analog; all others are digital.
C.10.8
Main Board Hardware Setup via Internal Jumpers
Hardware and firmware configuration of the Model 1088A/B is performed at the factory when this
option is ordered at the same time as the clock. The following instructions are intended primarily
for field installation.
Case Removal
To change the main board configuration for Option 12, 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.
