C.23 Option 36: Four Configurable Outputs 247
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.61 shows the locations
and Table C.18 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 Output Connector Function Jumper
J2 JMP1
J3 JMP2
J4 JMP3
J5 JMP4
Compare each jumper position with the items in Table C.18 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 Output Connector Mode Jumper
J2 JMP9
J3 JMP10
J4 JMP11
J5 JMP12
On the 1088A/B two signals are defined as analog: modulated IRIG-B and
±
5 V deviation. On
all Mode jumpers, JMP9 – JMP12, analog signals use position B. Digital signals, like unmodulated
IRIG-B, use position A.
Clock Model Selection
Jumpers JMP13 and JMP14 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 JMP13 or Option 36 will not operate correctly in the Model
1088A/B.
