Enter Key

Alphanumeric Keys

The enter ( ) key allows you to launch the focused item or to complete an editing action. It does not navigate you through a menu structure. For example, if you have the Cancel button in focus (highlighted) when you push the enter key, you will be choosing to cancel out of that particular window.

Tab Key

The tab ( ) key allows you to move between selectable controls.

The alphanumeric keypad allows you to select both letters, digits, and other characters such as punctuation marks. It can perform a selection of options and data entry in either numeric or alphanumeric modes. The 375 Field Communicator will automatically determine the mode depending on the input necessary for the particular field.

When in alphanumeric mode, to enter text press the desired keypad button in quick repetition to scroll through the options to achieve the appropriate letter or number. For example, to type the letter Z, press the 9 key quickly four times.

The alternate function on the Tab and alphanumeric 5 key (insert) will be activated in future releases of the Rosemount 375 Field Communicator.
