Discrete Wiring
The Controller PCB contains four discrete input and four discrete output connections.
PAR 1 Input Connections
The input connections must be referenced to ground. A switch or relay contact may be
used to make this connection. The remote device should hold the input at logic ground
for at least 100 ms. Scale functions are performed when the input is held to ground
(leading edge triggered). The maximum recommended cable length between the remote
device and the JAGXTREME terminal is 10 feet (3.04 meters).
Each of the four PAR 1 inputs can be configured for different remote inputs including
input from the JAGXTREME keypad (Tare, Clear, Zero, Select, Escape, and Enter). PAR 1
inputs can also be configured for remote print, unit switching, alternate scale selection,
or template selection. Polarity (switch to ground or open a ground connection to initiate
remote input) can also be selected. Refer to Chapter 3.

PAR 2 Output Connections (Setpoints)
Each of the four PAR 2 outputs can be configured to announce Setpoints 1 through 12
coincidence. The 12 setpoint outputs can be configured to request either Feed or Fast
Feed, or announce setpoint tolerance status. The standard number of setpoints is 4.
Eight additional setpoints are available if a multifunction PCB is installed. PAR 2 outputs
can also be configured to announce “current scale status” conditions such as:
• Net or Gross Mode
• Gross Zero
• Motion
• Over Capacity
• Under Zero
Refer to Chapter 3 for details on configuring PAR 2 discrete outputs. Outputs are
negative-true, open collector type. PAR 2 outputs can be referenced to the 5 volt supply
available on the PAR2 connector or can sink up to 35 mA of current and have a
maximum voltage of 30 volts DC from an external source. The maximum cable length
between the remote device and JAGXTREME terminal is 10 feet (3.04 meters).
