Accusetter Manual - BC MacDonald & Co.

LVDT Jumper Settings
The following may be set on the signal conditioning module by means of jumpers: Buss
out pin assignments, buss in pin assignments, bussed in signal sum and difference, and
input amplification.
Input/Output Jumpers
To buss a signal from one Accusetter II to another connect an interface cable, Edmunds
#4550203, from the Input/Output "A" connector on the rear of one column to the
Input/Output "B" connector on the rear of the next column. Multiple columns may be
connected in this way.
If a signal is to be bussed out to another Accusetter II or external device the pin
assignment, from 1 to 6, must be set using the jumpers as follows. Note: To avoid buss
contention, assign one pin per signal. See figure 4.5.
A OUT - Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input A. This is a low level signal.
B OUT - Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input B. This is a low level signal.
C I/O - Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input C to another Accusetter or external device or to buss in a signal from
another Accusetter to input C. This is a low level signal.
D I/O - Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input D to another Accusetter or external device or to buss in a signal from
another Accusetter to input D. This is a low level signal.
SUM HI - Use this jumper to assign a pin number, 1 through 6, to buss out the sum of
all inputs included in the check designated as being "Buss Out" on the System,
Comm menu. This is a high level signal (+/-2.5V).
SUM LO - Use this jumper to assign a pin number, 1 through 6, to buss out the sum of
all inputs included in the check designated as being "Buss Out" on the System,
Comm menu. This is a low level signal.
NOTE: Each pin can have only one input or output assigned. For example, if A OUT is
assigned to pin number 6 then no other input or output can be assigned to pin number 6.
NOTE: If an output is not used place the jumper on only one pin .
