The Master Relay Control Panel
When the software is initially loaded the user is presented with the Master Relay Control Panel
This panel allows basic control of the three Denkovi Relay Boards – all relays can be switched individually or on mass
The first thing the user must do is connect the relay boards to the correct comm ports
defaults of COM4 COM5 and COM3 are present in the text boxes but it is possible that these could be incorrect if hardware has been modified or plugged differently on the computer

Once the comm ports have been correctly connected there are four options available :-
• Switch Relays on/off using this master control panel (Static - No railway logic involved)
• Load the Layout Relay Control Panel so that relays can be switched on/off according to railway functions
• Load the Servo Control Panel
• Load the Tracking and DigiBee Control Panel
