120 Options List
Parallel Data Output Mode
Full operation in the parallel data output mode utilizes all 50 contacts of the output connector.
However, use of any combination of digital signal outputs or analog signal outputs will reduce the
number of data bits available by up to four (data bits 19, 27, 44, and 45). For details, refer to the
sections pertaining to these individual functions.
The functions of the individual data bits are defined for specific customer applications, upon request.
To configure Option 06 for parallel data mode, observe the following steps:
a. Set jumper JMP1 to position ”B”. This jumper enables the parallel data output mode.
b. Set jumpers JMP2, JMP3, JMP4, JMP5, and JMP11 to position ”A” (these settings will
vary if the analog and/or digital signal outputs are used; refer to the applicable sections for
more information on these functions).
c. If it is desired that the parallel output data be synchronous to the 1 PPS output, set jumper
JMP6 to position ”A”; for non-synchronous operation, set this jumper to position ”B”.
Digital Signal Outputs
The four digital signal outputs can be individually enabled and configured, using the following
steps:
a. Set jumper JMP11 to position ”A”. This enables the digital signal output mode. At the
same time, making this jumper selection eliminates parallel data bits 19, 27, 44, and 45.
b. To enable digital signal output number 1, set jumper JMP2 to position ”A”.
c. To set the type of output signal for digital signal output number 1, make the appropriate
selection on jumper JMP8 (refer to Figure 2). Note that positions 1 and 2 correspond to
analog signal outputs, and will be occupied by a jumper only if analog signal output number
1 is enabled.
d. To enable digital signal output number 2, set jumper JMP3 to position ”A”.
e. To set the type of output signal for digital signal output number 2, make the appropriate
selection on jumper JMP7 (refer to Figure 2). Note that positions 1 and 2 correspond to
analog signal outputs, and will be occupied by a jumper only if analog signal output number
2 is enabled.
f. To enable digital signal output number 3, set jumper JMP4 to position ”A”. This also
eliminates the possibility of using analog signal output number 1.
g. To set the type of output signal for digital signal output number 3, make the appropriate
selection on jumper JMP9 (refer to Figure 2).
h. To enable digital signal output number 4, set jumper JMP5 to position ”A”. This also
eliminates the possibility of using analog signal output number 2.
i. To set the type of output signal for digital signal output number 4, make the appropriate
selection on jumper JMP10 (refer to Figure 2).
