The following diagram shows the module outline defining the placement of
the various shunts, looking at the primary side of the board, with the
terminal block pointing up. A brief description of each follows.

JP8 Setup

There are eight shunts corresponding to eight inputs, respectively,
that exist to support the 0 to 20mA or 4 to 20mA current input
selections. JP1 corresponds to channel 0, and JP8 corresponds to
channel 7. The shunts of JP2 through JP7 follow for channels 1
through 6, respectively. These shunts are two pin headers that only
need to be connected if a channel is to be configured for current
input. If the channel is to be used for any other type (thermocouple,
millivolt, voltage for channels 0 through 3, or thermocouple,
millivolt, voltage, RTD, or resistance for channels 4 through 7), then
the pins are to be left open and unconnected.

JP11 Setup

Located in the bottom right hand corner, JP11 should always have
pins 1 and 2 connected as shown. This shunt is used during
manufacturing of the module, and should never be moved by the
user.
