Custom Applications
JagBASIC
JagBASIC provides for the development of easy-to-use custom applications. JagBASIC
programs reside along side the standard JAGXTREME terminal program. The JagBASIC
interpreter runs as a separate task using the terminal’s multi-tasking operating system.
This allows the custom JagBASIC program to interact with the other JAGXTREME terminal
tasks and resources using the terminal’s exclusive shared memory design. For example,
to monitor a scale gross weight, the JagBASIC program relates a BASIC variable to the
terminal shared data variable for gross weight then uses the BASIC variable as desired.
All of the shared memory in the terminal may be accessed by the JagBASIC program
using this construct.
The high level of integration permits the programmer to exploit the standard functions in
the JAGXTREME terminal, making it easier to implement solid solutions in record time.
To print a standard ticket or report, a JagBASIC program can load data into a
JAGXTREME terminal shared data variable then print by using a standard template that
is designed in the terminal setup. Rather than monitoring setpoint coincidence in the
JagBASIC program, a standard setpoint shared data variable can be loaded in the
program then monitored by an associated JAGXTREME terminal scale task.
Power Requirements
! 85 to 264 VAC with a line frequency of 47 to 63 Hz.
! Power consumption -- 20 Watts maximum.
! Power termination -- single three-position removable terminal strip.
! The wire size range -- 16 to 12 AWG.
Note: The integrity of the power ground for equipment is important for both safety and
dependable operation of the JAGXTREME terminal and it’s associated scale bases. A
poor ground can result in an unsafe condition if an electrical short develops in the
equipment. A good ground connection is needed to assure extraneous electrical noise
pulses are minimized. It is important that equipment does not share power lines with
noise generating equipment like heavy load switching, motor starter circuits, RF thermal
heaters, inductive loads and the like.
To confirm ground integrity, a commercial branch circuit analyzer is recommended. This
instrument uses a high amperage pulse to check ground resistance. It measures the
voltage from the neutral wire to the ground connection and will provide an assessment
of the line loading. Instructions with the instrument give guidelines about limits that
assure good connections. Visual inspections and a query of the user will provide
information about equipment sharing the power line.
The power line for the JAGXTREME terminal must not be shared with equipment such as
motors, relays, or heaters that generate line noise. If adverse power conditions exist, a
dedicated power circuit or power line conditioner may be required.
