#2 tab is selected. The user should not have to reload the configuration except when the parameters need to be reset to those already saved in the switch. The load configuration button will load the configuration from the connected switch and assume these apply to the selected Unit.

View Module Configuration:

Each unit’s configuration can be reviewed on one screen by selecting the appropriate tab and clicking the View Module Configuration button. Any changes from what was read from the switch will be shown in red. The page can then be printed to the default Windows printer for review or for attachment to the switch.

Configure Switch:

Before exiting the program, all changes should be saved to the switches. The parameters will be saved to the connected switch. Care should be taken to ensure that the correct Unit is connected, its setup jumper installed, and power applied before saving.

NOTE: Once changes are saved to the switch they cannot be reset automatically. Be sure to review all changes before saving.
