3.4.3 Device Number Setup
Note:
To prevent possible interference from multiple users environment, each remote will be set to a specific User Device Number (User DN#, between 00 to
99). If the User DN# has not been setup, the OSD will prompt the user to program a device number setup.
To program, press <Re-Sync> key first then press <CH+> key, hold down both keys for about 3 seconds, then released:
<<Re-Sync> + <CH+>>
1. The software is now expecting the user to enter two digit numbers representing the device number by press/release <Digit> <Digit> keys. (In
the software test module, this process completes with 2 LED blinks indication).
2. If <AnyKey> key, other than <Digit> keys, is pressed after the above sequence, the software will abort the Device Number Setup mode. (In
the software test module, this error condition will be indicated by a long LED blink).
3. Within 10 seconds (timeout value) after the above sequence entry, if NO key is pressed (or the timeout expired between <Digit> key press),
the software will exit the Device Number Setup mode and the remote will retain the current settings. The software will then return to its normal
operation without having the device number updated. During this 10 seconds time, if the Pointer device is activated, the software will exit the
Device Number Setup mode and will service the pointer movement of the remote.
Each Remote has a Device ID and a Device Number (00-99). The Device ID shows the category of the Remote. The Host will validate the
received data packet from the Remote, by checking the Device Number, to see if it has been registered for that Device ID or not.
After the channel synchronization, the Device ID and Device Number of each Remote will be registered in the Host.
Note
: For both Keyboard and Remote Control, the Keypad and Pointing Device have the same Device Number. During synchronization, only Device ID
of the Keypad and the Device Number of the Pointing Device will be sent. The Host should also register the Device Number for the Pointing Device of
the corresponding device.
