How to operate the Count Down Timer Component?
In operation mode you can start, stop and modify the preset value of the Count Down Timer. Following are the steps to do this via the Gateway or using an Action.
Using the Gateway
It is possible to operate the Kaleido-K2 using the Gateway. The Gateway is a very flexible and powerful tool that is usually used through a program but the Gateway can also be used via telnet. The following explanations will guide you through the use of the Gateway via the HyperTerminal software.
Open the HyperTerminal software on your computer, and from the "Program" menu choose "Accessories", "Communications" and "HyperTerminal". A dialog will appear, asking you to enter a name for the connection and to select an icon.
A second dialog, "Connect To", will appear. In the "Connect using" dropdown field choose "TCP/IP (Winsock)". Two new fields will appear, in the "Host address" field enter the IP address of your Kaleido-K2 and in the "Port number" field enter "13000". This indicates that you want to connect to your Kaleido-K2 via the port 13000. Click on the "OK" button.
To be able to see the typed character:
- Select "Properties" from the "File" menu, the "Properties" dialog box appears.
- Go to the "Settings" tab, click on the "ASCII Setup..." button located at the bottom of the dialog
- Select "Echo typed characters locally".
- Click on the "OK" button and click again on the "OK" button from the "Properties" dialog.
You can now see the typed characters appearing in the console.
Commands can be sent to the Gateway while a session is open. There is no maximum number of commands that can be sent in a session. A session must be opened and closed using two specific commands. While sending a command the syntax must be exact. If you make a mistake in the syntax, the command will not be understood. Here is a rough example of a session:
Open a session
send command
send command
...
send commandClose the session.
To open a session enter the following command:
<openID>IP_ADDRESS_0_4_0_0</openID>
Where:
If the Gateway receives the command, and recognizes it as a command that can be handled, it will send you the following response:
<ack/>
If the command cannot be recognized the following message will appear:
<nack/>
If you received this message, please consult the Gateway documentation included on the Kaleido-K2 CD to troubleshoot the installation and communication.
You are now ready to send commands. There are commands to start the Count Down Timer, stop the Count Down Timer, reset the Count Down Timer and modify its configuration.
To configure a Count Down Timer:
<setKTimer>set id="ID" preset="99:99:99" direction="Direction" loop="State" </setKTimer>
Where:
To start, stop or reset a Count Down Timer:
<setKTimerTrigger>set id="ID" trigger="Trigger"</setKTimerTrigger>
Where:
You can execute as many commands as you want. When you want to stop sending commands you have to close the session. The following command is used to close a session:
<closeID>IP_ADDRESS_0_4_0_0</closeID>
Where:
Your session is now closed.
To end the communication, select the "Disconnect" icon from the toolbar.
Using an Action
Set the Preset Value and Start the Count Down Timer
You can use an Action to modify the preset value and start the Count Down Timer at the same time. This means that you could, with a single click on your Layout, set the preset value of a Count Down Timer to 15 seconds and start counting. This operation can be done in either off-line or on-line mode. The following explanations will guide you through the operation while in on-line mode.
Here are the steps to create the Action that will start the Count Down Timer:
- Open KEdit
- Select "Open" from the "File" menu and then the "Online..." menu item or press the "Ctrl-O" keys.
- Select the Kaleido-K2 from the list.
- Click on the "Open" button. If the current Layout doesn't contain a Count Down Timer Component add one.
- Select the Count Down Timer and open the "Configuration Panel" by selecting "Configuration Panel" from the "View" menu or press the F5 key. Note the Timer ID assigned to the Count Down Timer.
- Open the Action Browser by selecting "Action Browser" from the "View" menu or by pressing the F9 key.
- Select the "New" button, the "Action Configuration" dialog should appear.
- Enter a name to associate to the Action in the "Name" field.
- Click in the "Type" column of the first row and select "Timer". The Timer Configuration dialog should appear.
- Enter the Timer ID of the Count Down Timer you want to modify and start.
- In the preset field enter the new preset of the Count Down Timer. This field works like a time code field: if you want to set the preset to 30 sec enter 3-0 and it should display "00:00:30".
- Select the direction of counting: indicating "Up" will make the Timer go from 0 to the specified preset and specifying "Down" will make the Timer go from the preset to 0.
- Click on the "Ok" button.
- Click on the "Save" button.
The Action is now created and it should appear in the list of the Action Browser. To be useful this Action needs to be associated with a Trigger. Here is how to configure your Layout so the defined Action will be executed when a Text Label Component is clicked:
The Action is now assigned to the single click Trigger of the selected Text Label Component. To test what you just configured go on your Kaleido-K2 and, using the mouse, click on the Text Label to which you assigned the Action. You should see your Count Down Timer modified and started.
Stop the Count Down Timer
You can use an Action to stop the Count Down Timer. This means that you can, with single or double clicks on your Layout, stop the Count Down Timer.
To create the Action follow the steps described in the previous section but when clicking in the "Type" column of the Action List choose the "Timer Pause" option. The "Timer Pause Configuration" dialog should appear:
The Action is now created and it should appear in the list of the Action Browser. To be useful this Action needs to be associated with a Trigger. Here is how to configure your Layout so the defined Action will be executed when a Status Indicator Component is double-clicked:
The Action is now assigned to the double click Trigger of the selected Status Indicator Component. To test what you just configured go on your Kaleido-K2. Make sure your Count Down Timer is currently counting and, using the mouse, double click on the Status Indicator to which you assigned the Action. You should see that the Count Down Timer stops.
