3.3 Operational Features Conventions and Notations The operation of the remote control and the programming sequence use the following shorthand notations. The relational operator <<>> around a key is an instruction to press and hold the key for 3 seconds. For example: <> Press RESYNC and hold for 3 seconds The relational operator <> around a key is an instruction to press the key and then release. For example: Viewsonic Tweety RF Remote Universal Electronics Inc.

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 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 key is held down, and it will be reset (or cleared) when the key is released. 1.1.
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.

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.

If another key, say, is pressed while is still held down, the Make code data packet of the same K1 key will be sent out as defined above. Until is released, two data packets of Break code will be sent with 10 ms delay between data packet. Since is now still held down, two data packets of Make code will be sent with 10 ms delay between data packets. Note: Packet gap between the last Break Code of K1 sent and the first Make Code of K2 sent is 10 ms..
Timing Events versus Data Packet transmission for various operational situations: 3.4.

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.
Case of Re-Sync data packet sent: {{+}} A key is pressed while 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 Re-Sync data packets will be kept sending out as long as the keys are held down. Viewsonic Tweety RF Remote Universal Electronics Inc. Confidential Rev 2.

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 key first then press key, hold down both keys for about 3 seconds, then released: < + > 1.
3.4.
If another key is pressed/released while the 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 key is pressed/released while key is still held down.
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 key first then press key, hold down both keys for about 3 seconds, then released. The software will enter the E2 Initialization mode WHEN the key is pressed and released after the above described sequence. < + > 1.
3.4.6 Factory Test Mode(s)1 To enter this RF Channel test mode, press and hold a combination keys <<1>+<3>> for at least 3 seconds then released, within 6 seconds after the battery/power is applied to the unit: <<1> + <3>>2 The software will start with setting up RF-channel 1 and send through the Transmitter the entire packet for the first channel continuously for the first 300 ms, with a 10-20ms gap between each channel.
Key Test (Also used in Factory Test for Key): An integrated hardware/firmware/software test unit will be designed for the Key Test. This Key Test Unit can be used during this project software development as well as for factory test in an actual production manufacturing. No special combination key sequence is required to get into this Key Test mode.
3.4.6.1 Firmware Unit: This so-called “unit” is actually a firmware portion that processes to keep 5 bytes of the 11-byte data packet after striping off all the Sync bytes and Preamble bytes. It then output these 5 bytes through the RS-232 protocol format.

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.

3.4.7 Low Battery Indicator When the batteries in the unit reach approximately 3.4 Volts the remote will send a specific frame of data to indicate the remote batteries are low. The user will be prompted via an onscreen display to change the batteries. When the unit's batteries reaches 2.9 Volts +/- 200 mV the remote will not respond to key presses.
