DGT / Input Engine console

On top of the Input Engine window, a console monitors the communication between Scid and the driver engine. Usually, this is of no interest to the user, but it may provide helpful hints in case of malfunction. All commands sent by Scid are prepended by an arrow to the right, all answers retrieved from the driver engine by an arrow to the left. Below the console, the actual invocation of the driver by Scid shows up for information.

Moves sent for allows to limit the moves sent by the external hardware. For game input the board should of course send the moves for both sides. For actually playing a game however, the moves made by the opponent should be ignored, as Scid would otherwise notify them as "illegal moves".

The small board on the right shows the current position.

If a move is made, in the area between the buttons and the small board the move performed (move area) on the external board is shown in figurine long algebraic notation. Valid moves show up on a green background while illegal moves show up on a red background. Additionally, illegal moves are announced by the alert sound, if Scid has sound enabled. Depending on the settings, the moves are additionally announced.

The Info button calls up information from the driver engine. The extend of this information depends on the engine, but it should usually give as much as is available about the external hardware and the driver itself. Additionally, the external driver will return the current position on the external board as FEN which is then compared to Scid's internal representation. Discrepancies show up in the console and issue an alert.

In case Scid and the external board got out of sync, the Synchronise button can be used. A new game is set up and the start position is set to the position on the external board.

The Close button finally disconnects the external hardware and closes the console.

Special Features

The following features depend on the driver engine and hardware that is used. Their description is based on the functions available with the DGT Electronic Chess Board and specified in the Input Engine Protocol description. Some of these functions however rely on the fact that the hardware is able to recognise the pieces on the board and their current placement.

Position setup

The position setup mode is invoked by removing both kings from the board. In this mode the move area is colored yellow and shows the White king and the string Setup.

In setup mode any valid position can be set up on the external board, however Scid's internal representation is not updated till finished.

To end the setup mode both kings are set back to the board. Note, that the king of the side to move is set back last, that is if white should be on the move first set back the black king, then the white king. Now, the move area shows the black Queen and the string OK.

End a game

In game input or game play one can end the current game by setting both kings into the center squares of the board. The result is given as follows:

In either case the Save / Add game dialogue shows up to allow filling in the game tags and to store the game in the current database.

Start a new game

A new game can be stared by entering setup mode (ie. removing both kings) and setting up the start position. To notify, that Scid has recognised the call for a new game the move area is colored in blue showing the white king and the string OK.
