Instructions and Help about Will 8850 Form Navigation

The device simulator makes it easy to simulate two-way communication between a GPS tracking device and your cygnus track web portal using the two-way communication tab you can see a list of device commands that have been received by your device but how do you actually initiate a device command well to do this you'll want to start by logging into your cygnus track web portal and going to the tracking screen that you can see here then on the sessions panel on the left side here click on the small green blip icon next to one of your devices a dialog is going to open from here you can send a command to this particular device for example let's tell it to unlock the doors of the vehicle that its installed in this is a pretty handy feature if the driver locked his keys in his truck for example select unlock doors from the commands list and then click send you'll say device command message was sent now let's send another command with a custom message attached and that one is send message to device display Tandi for GPS devices that have it display screen on them and you can just inform the driver that you know hey I unlocked your doors for you so then you can see that on the screen and then just click send again to send that message and again it says device command message was sent now you can go ahead and close that dialogue and then come over here to the device simulator make sure you're on the two-way communication tab and now click the refresh button here listed next to that receive commands list the list is going to update with the two commands that we just sent from Cygnus track it's showing the most recent one first you can see our simulated tracking device display here is showing the message that we send telling the driver that we unlocked his doors if we open this list and choose the other command we can see the actual unlock doors command that we sent first if you click the view XML button you can see the actual xml code behind the selected command this code is handled by the device listener which is a special piece of software that transforms XML data like this into actual commands the GPS tracking device can interpret being able to view it here is especially useful for debugging when you're writing your own custom device listener so now that we've seen how devices can receive commands from cygnus track let's see how to send back a response from the sender response section down here you can choose to send a response back to Cygnus track for each command that was received and these are just some common responses that tell Cygnus trackie of the status of the command for example that it was delivered successfully that it was sent without any acknowledgement or that an error occurred somewhere along the way when you choose response and click the send response button the command you're responding to will be cleared from your list here in the device simulator you can always verify if and how commanders received right from the cygnus track web portal on your tracking screen just click that little green blip icon again and then choose the view command history button from the left sidebar you'll see a list of all commands that were sent to this device and in the far right column the status of that command note that when you're using the simulator if you don't respond to a command within a certain amount of time the command will show a status of time out here this should give you a pretty good idea of how the device simulator can be used to demonstrate how your GPS tracking devices and your cygnus track web portal work together and communicate with each other the two-way communication tab of the simulator can be very handy when you're developing a custom device listener as it lets you test to ensure that device communication is being handled correctly.
