C.16 Option 36: Four Configurable Outputs 183
General Information
Option 36 incorporates a flexible output selection system using jumpers on the Option 36 printed
circuit board. Each of the four rear-panel BNC-type I/O connectors, included with Option 36, can
be configured to perform any of the available output functions. Figure C.43 shows the locations
and Table C.11 indicates the functions for all of the jumpers on the Option 36 board.
Function Selection
Jumpers JMP1, JMP2, JMP3 and JMP4 control which output signal arrives at a respective output
connector.
Desired Signal Jumper Output Connector
JMP1 J2
JMP2 J3
JMP3 J4
JMP4 J5
Compare each jumper position with the items in Table C.11 to match your desired signal type.
For example, to provide unmodulated IRIG-B at output connector J2, set JMP1 jumper pin to
position 3. If all of the four outputs need to be set to provide unmodulated IRIG-B, place each
function jumper to position 3.
Mode Selection
Jumpers JMP9, JMP10, JMP11, JMP12 control the signal driver for each output: analog or digital.
Make sure to select these output mode jumpers for each output. For each output, position A selects
a digital driver and position B selects an analog driver. The table below indicates the correct jumper
for each output.
Desired Mode Jumper Output Connector
JMP9 J2
JMP10 J3
JMP11 J4
JMP12 J5
On the 1093A/B/C only one signal is defined as analog: modulated IRIG-B. However, Option 92
must be installed to produce modulated IRIG-B on the Model 1093A/B/C. On all Mode jumpers,
JMP9 – JMP12, analog signals use position B. Digital signals, like unmodulated IRIG-B, use
position A.
Clock Model Selection
Use one of two jumpers, JMP13 or JMP14, to select the clock model in which Option 36 is mounted.
JMP13 selects for Model 1088B and JMP14 selects for Model 1084A/B/C, Model 1093A/B/C and
Model 1201B/C. Make sure to to set this jumper to JMP14 or Option 36 will not operate correctly
in the Model 1093A/B/C.
