How does the Re-Sync operates and When the “Re-Sync” code is sent:

Activating the <Re-Sync> key allows the user to send the “signature data” and to synchronize the RF Transmitter and Receiver RF-channel.

To activate the Re-Sync function:

 Press <Re-Sync> key first.  While <Re-Sync> key is held down, press a digit key <d> where d is any digit keys from 1, 2, 3, …, 8, 9, 0 representing RF-channel 1,

2, 3, …, 8, 9, 10 respectively.

The process can pictorially be represented as below:

{{ <Re-Sync> + <d> }} <d>

is <Digit> Key for Digit 1, 2, 3, …, 9, 0

Press/Release <d> key, while <Re-Sync> key is held down. The system first sets up “d” RF-channel for RF Transmitter (digit number corresponding to channel 1 through 10), it then sends out the “Re-Sync” Make code data packet, minimum of 10 or more, as long as key still held down.

 If the <Re-Sync> and <d> keys are both

released

 If another <Digit> key is

pressed/released while the <Re-Sync> key is still held down

The “Sleep” code data packet will be sent when no key activities are detected after 5 seconds (Refer to Sleep Code transmission section for details).  The system will setup another RF-channel, corresponding to that digit key, for the Transmitter, it then

sends out another “Re-Sync” Make code data packet in that RF channel setting.

 This process will be repeating as above in response to different <Digit> key is pressed/released while

<Re-Sync> key is still held down.

This Re-Sync signature data transmission process will be repeated as described above each time another <Digit> key is pressed/released until both Transmitter and Receiver units match its selected RF-channel. This channel frequency will then be used to transmit the data packet.

3.4.1 Definitions

Stuck Key Time-out

After any key is pressed continuously for 60 seconds, the remote will stop sending data packets and turn off RF transmission to conserve battery life. Transmission can begin again, after all keys are released and key is pressed.

How and When the Stuck-Key code is sent:

The Stuck-Key Code Data Packet will be sent:

 After two data packets of the Make Code of the detected key press, <K1> say, have been sent out. If this (same) key, <K1>, is still being held down for more

than 60 seconds, then two data packets of Stuck-Key code will be sent with 10 ms delay time interval between data packets. A Make Code data packet of the same key sent every 70 ms time interval during this 60 seconds stuck key condition.



For the pointing device, after sending out the X-Coord and Y-Coord continuously up to 2 minutes which is the time to be considered as stuck key timeout for pointing device. Two data packets of Stuck Code will be sent. Two data packets of Sleep Code will be sent following the Stuck Code data packet. The RF Transmitter will then be turned OFF.



Sleep Mode

This is the idle state of the micro-controller when it draws the least amount of current. Upon entering the idle mode, the remote will transmit a unique byte (FD) to notify the receiver that it is entering into the sleep mode.

Key Type Data Packet Transmission, a Summary:

All keys including the pointing device buttons are Make/Break type. When a key or button is pressed, the remote will transmit the data packet as shown in the protocol on previous pages.

For reliable data transmission, keystroke and control push buttons data packets are transmitted twice wirelessly from the Remote Control RF Transmitter. The transmission is one time for Keep-Alive code and a minimum of 10 times for Re-Sync code.

Followings are some scenarios of key press:

Case of a normal Key pressed/released:

Key Pressed Make Code sent. Key Released Break Code sent, RF Transmitter turned OFF.

If no key press is detected after 5 seconds, RF Transmitter is turned ON and Sleep Code is sent. After that the RF Transmitter is again turned OFF and the unit goes to SLEEP mode. If a key press is detected within 5 seconds, that key data transmission will be serviced as described above. If a key pressed then stuck for a long time, then Make Code of the same depressed key will be sent for every 70 ms time interval within 1 minute from the time the original Make code sent. When 1 minute duration is expired, a Stuck code will be sent, followed by Sleep code and the RF Transmitter is then turned OFF. Note that the software would only be able to go to STOP (or SLEEP) mode when a stuck key is released.

Case of Make code kept resend

(use <K1> and <K2> as an example):

<K1> pressed Make Code of K1 sent.

<K2> is then pressed while <K1> is still down and both keys are now down within 1 minute. The Make code of K1 will be sent for every 70 ms time interval as described above, until one of the following conditions occurs:

<K1> is released first while <K2> is still held down. Break code of K1 will be sent and Make code of K2 will be sent after 70 ms. <K2> is released first while <K1> is still held down. Nothing changes except the same Make code of K1 will be sent for every 70 ms time interval. Until <K1> is released and its Break code is sent.

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.

Indicates a key that had never been pressed and/or released, or the key is malfunctioned that the remote could not detect when pressed. Indicates when the key is pressed and the software receives its Make Code corresponding to that key. Indicates when the key is released and the software receives its Break Code corresponding to that key.

•

Two allocated display locations on the screen monitor are to be programmed to show the value of X-coordinate and Y-coordinate of the Pointing Device. These values are data received in Byte2 and Byte1 when the pointing device on the remote control is activated (b2b1b0=100 in the Device Address / Status byte).

• An allocated display location on the screen monitor is to be programmed to show the status of the battery level condition. This status is to be decoded from bit b7 of Byte 3 (Device Address / Status byte) in the received data packet.
