2 Operation

2.1. Overview

This chapter provides the navigation, basic features and functions of the IND256x terminal. IND256x functions can be configured through the setup menu – refer to Chapter 3,
The specific operation of each IND256x terminal depends on the options installed, the functions allowed in the setup menu, and the parameters configured.

2.1.1. User Security: Overview

Access to the terminal’s functions can be restricted according to the site’s security policies. Restrictions may reflect legal and regulatory requirements, or site-specific standards.
The IND256x uses a password security mechanism to protect the setup menu. The password function is off by default and can be enabled in setup.
Once set, the password must be kept safely. If the password is changed or forgotten, the setup menu and some terminal functions will not be accessible. To recover access and functions, a master reset must be performed, which will reset all user names and passwords and delete any custom configuration.
Configuration.

Tare refers to the weight of an empty container. It is generally used to determine the net weight of the container’s contents. Press the tare function key when an empty container is placed on the weighing platform to display a net weight of zero. When material is added to the container, the terminal displays their net weight.
When the empty weight of the container is known, the tare may be entered using the numeric keypad and pressing the tare function key to store the value. The terminal will display the net weight of the materials in the container. The keyboard tare must be allowed, so that this method can be used for key tare operation. If the auxiliary tare display is allowed, the tare value and tare type will be displayed in the bottom left of the screen.
Pushbutton tare must be enabled in setup in order to use either of these methods
for tare operation.
Press the print function key to initiate a demand output of data in the print template configured in setup. A serial or WiFi print connection must be configured to connect the template to the selected serial or WiFi port. When a print command is issued, they system line displays
for 3 seconds.
