I'm trying to get Door / window sensor DS90 to communicate with indigo wia W800 rf interface, some problems:

Here is what happens when I press the "tamper contact" button

Code: Select all

2006-10-08 20:00:15     Received RF     security command sensor alert (min delay) (ID 215)
2006-10-08 20:00:16     Received RF     security command sensor alert (min delay) (ID 55)
2006-10-08 20:00:18     Error   illegal security code byte 44
2006-10-08 20:00:19     Error   illegal security code byte 44
2006-10-08 20:00:19     Error   illegal security code byte 44


And here is what happens when I move the module close to magnet & away from it

Code: Select all

2006-10-08 20:00:47     Error   illegal security code byte C4
2006-10-08 20:00:48     Error   illegal security code byte C4
2006-10-08 20:00:49     Error   illegal security code byte 44
2006-10-08 20:00:50     Error   illegal security code byte 44
2006-10-08 20:00:54     Error   illegal security code byte C4
2006-10-08 20:00:54     Error   illegal security code byte C4
2006-10-08 20:00:55     Error   illegal security code byte 44
2006-10-08 20:00:55     Error   illegal security code byte 44


The Illegal security code byte C4 seems to come when the contact magnet comes close to the module and byte 44 when the magnet is taken away from the module. Always comes in pairs.


C4 / 44 are the illegal bytes if the module is set on "min delay", if the module is set on "max delay" the bytes are C0 / 40.

Actually it works corretly if the device is closed

Though, still if the device has it's case open it does give those undefined byte messages, most likely the device is transmitting that something "not-so-good" is going on

Interesting... none of the door/window sensors I've seen detect any type of case closed/open state. Looks like the DS90 must be different. Do you see a switch or something onto which the case lid presses?

Yep, it's called "tamper contact" in the manual. When the case is closed it is pushed down about halfway.

The tamper-contact is there to detect if someone is messing arround with your DS90. Like taking out the batteries, so it won't communicate with the alarm controller.
Nothing to worry about, as long as you leave the case closed.

But it would be nice if Indigo could send a nice log message when this happens. Or fire somes triggers, like one to release the cagedoor so the dogs can run free...
