CheckSum: The sum of Device Number + Device Address / Status + X-Coordinate + Y-Coordinate/Scan Code.
(Add all the indicated bytes without carry’s).
LEFT/RIGHT MOUSE key Operation
1. When the
<Left> key is pressed, its corresponding pointing device left key status (Bit 3) in the Device Address / Status Byte will be set.
This bit will be set as long as the <Left> key is held down, and it will be reset (or cleared) when the <Left> key is released.
1.1. While the <Left> key is held down:
a) If the Pointing Device is not active, the transmitted data packet will have Left key status bit in the Device Address / Status Byte
set and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained all zeros.
b) If the Pointing Device is active, the transmitted data packet will have Left key status bit in the Device Address / Status Byte set
and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained the X and Y positional values of the Pointer movement.
1.2. While the <Left> key is pressed and held down, if another key (other than <Right> key) is now pressed, the pointing device Left key
status bit in the Device Address / Status Byte will be reset.
a) If the Pointing Device is not active, no data packet will be transmitted. Both keys must be released for the remote to return to its
normal operation
b) If the Pointing Device is active prior to the key presses as described in 1.2 above, the transmitted data packet will have Left key
status bit in the Device Address / Status Byte reset and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained the
X and Y positional values of the Pointer movement.
2. When the <Right> key is pressed, its corresponding pointing device right key status (Bit 4) in the Device Address / Status Byte will be set.
This bit will be set as long as the <Right> key is held down, and it will be reset (or cleared) when the <Right> key is released.
2.1. While the <Right> key is held down:
a) If the Pointing Device is not active, the transmitted data packet will have Right key status bit in the Device Address / Status Byte
set and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained all zeros.
b) If the Pointing Device is active, the transmitted data packet will have Right key status bit in the Device Address / Status Byte set
and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained the X and Y positional values of the Pointer movement.
2.2. While the <Right> key is pressed and held down, if another key (other than <Left> key) is now pressed, the pointing device Right key
status bit in the Device Address / Status Byte will be reset.

a) If the Pointing Device is not active, no data packet will be transmitted. Both keys must be released for the remote to return to its
normal operation
b) If the Pointing Device is active prior to the key presses as described in 2.2 above, the transmitted data packet will have Right key
status bit in the Device Address / Status Byte reset and the X-Coordinate Byte and Y-Coordinate / Scan Code Byte contained the
X and Y positional values of the Pointer movement.
3. When
<Left> and <Right>) keys are both being held down (with one key is pressed before the other), the corresponding pointing device
left key status (Bit 3) and right key status (Bit 4) in the Device Address / Status Byte will both be set. These bits will be set as long as
the <Left> and <Right> keys are held down. If any one of these two keys is released first, its corresponding status bit will be reset while
the corresponding status bit of remaining key remains set. Both bits will be reset (or cleared) when both keys are released. During this
time, if the Pointing Device is not active, the X-Coordinate Byte and Y-Coordinate / Scan Code Byte will be all zeros in the transmitted data
packet.
Note: It is up to the Host application software to make use of the case where both left and right key status bits in the Device Address /
Status Byte are set. This condition would indicate that both <Left> and <Right> keys are currently being pressed and held down.
4. When the Pointing Device is active and one (or both) of <Left> (or <Right>) key is pressed, the X-Coordinate Byte and Y-Coordinate /
Scan Code Byte will be updated with the X and Y value of their corresponding positional movements. The transmitted data packet will
have the corresponding Left (or Right) key status bit in the Device Address / Status Byte set or reset accordingly.
Note:
If both keys <Left> and <Right> are pressed at the same time, this would be considered as invalid (simultaneously key press). There will be
no data packet sent out in this case.

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
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).
If another <Digit> key is
pressed/released while the <Re-Sync>
key is still held down
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.

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.

If another key, <K2> say, is pressed while <K1> is still held down, the Make code data packet of the same K1 key will be sent out as defined
above. Until <K1> is released, two data packets of <K1> Break code will be sent with 10 ms delay between data packet. Since <K2> is now still
held down, two data packets of <K2> Make code will be sent with 10 ms delay between data packets.
Note:

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.
MAKE 10ms MAKE BREAK 10ms BREAK
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.

Case of Re-Sync data packet sent:
{{<Re-Sync>+<Digit>}} A <Digit> key is pressed while <Re-Sync> key is held down:
A minimum of 10 data packets of Re-Sync code (0x76) will be sent with 10 ms delay separated each data packet. Or the

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.

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
No Break Code data packet for “Re-Sync” will be sent. 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).

Universal Electronics Inc. Confidential Page 30 of 63
If another <Digit> key is
pressed/released while the <Re-Sync>
key is still held down
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.

3.4.5 E2 Initialization
EEPROM Initialization:
Note: The EEPROM device must have been previously initialized for the remote to be able to
get into the Factory RF Channel Test Mode.
Press <Re-Sync> key first then press <CH-> key, hold down both keys for about 3 seconds, then
released. The software will enter the E2 Initialization mode WHEN the <Enter> key is pressed
and released after the above described sequence.
<<Re-Sync> + <CH->>
1. If <Enter> key is pressed/released after the above sequence, the software will initialize
the EEPROM. (In the software test module, this process completes with 4 LED blinks
indication)
2. If <AnyKey> key, other than <Enter> key, is pressed after the above sequence, the
software will abort the EEPROM Initialization mode. (In the software test module, this
error condition will be indicated by a long LED blink).
Within 10 seconds (timeout value) after the above sequence entry, if NO key is pressed, the
software will exit the EEPROM Initialization mode and the EEPROM device will not be initialized.
The software will then return to its normal operation. But during this 10 seconds time, if the
Pointer device is activated, the software will exit the EEPROM Initialization mode and will service
the pointer movement of the remote.

3.4.6.2 Software Unit:
This so-called “unit” is actually a software portion (in the integrated Key Test Unit). After it
receives a data packet of 5 bytes, as described above, through the RS-232 communication
protocol, it will display the output on the computer screen monitor. The display output information
will depend on the data input information received from the RS-232 inputs.
The display output will be designed as such:
• All 34 keys (Table2, columns 1 & 2) are to be programmed to be graphically displayed as key
buttons (with proper key label if possible). A color-coded scheme are to be designed to
visually represent the key status condition depending on (b2b1b0=010 in the Device Address
/ Status byte).
Color-coded Key press status
Gray
Indicates a key that had never been pressed and/or released, or
the key is malfunctioned that the remote could not detect when
pressed.
Red Indicates when the key is pressed and the software receives its
Make Code corresponding to that key.
Green 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.
• An allocated display location on the screen monitor is to be programmed to show the Device
Number. This value is to be extracted from Byte4 in the received data packet.
