Revision 0.1 1. 2/16/2001 Introduction This document gives the minimum firmware specification required for a Custom Wireless NMB Keyboard with Pointing Device which is intended to be used with the Viewsonic Display Monitor. 2. Overview This battery-powered remote keyboard transmits RF signal to the Base Unit (RF-Receiver), which connects to the Viewsonic Large Screen Monitor display unit through an UART serial interface. The communication medium is 2.4GHZ. It has 10 programmable channels and each remote unit has its Device ID to avoid interference. Functional Block Diagram NMB Keyboard with Pointing RF TX Base Unit Receiver (UART) RX RF TX UEI Remote Control TX Viewsonic Large Screen Display Monitor Figure 1: Keyboard/Remote, RF- Receiver and IP-Board interface (UART) • • The NMB remote devices communicate wirelessly through the Base Unit (RF-Receiver) one way and the Viewsonic Display Monitor interfaces to the Base Unit through an UART port. The NMB keyboard and the UEI Remote must have a minimum distance of one meter from the RF-Receiver for proper operation. 3. UART Interface The UART interface requires only four lines, Receive (RX), Transmit (TX), GND, and +5Vcc. The communication link will be half-duplex; meaning that each side is either a RF-Receiver or the HOST at any given time. 3.1 Protocol Format of RF-RECEIVER (UART) to the HOST. The RF-Receiver communicates serially with the Host at 9600-baud over a 4-lines connection. Data packets are exchanged over the Receive and Transmit line.

The keyboard will test the checksum of the read-only memory (ROM), and random access memory (RAM) test. On satisfactory completion of the test, keyboard scanning begins and the pointing device will begin scan the sensor. 5. Sleep Mode The keyboard and the pointing device unit are to provide reduced power consumption sleep mode. If no data packet is transmitted within XX seconds, RF transmitter can go to sleep mode. While in this mode, the unit must maintain the current status. 6. Wake Up Mode When the keyboard key or pointing device is pressed or moved, the unit will wake up and transmit the key data or movement data. Revision 0.1 7. 2/16/2001 Data Packet It is recommended that for the FSK direct modulation system of the RF communications, the Data Format below is recommended. Sync Byte Preamble 16 bits 16 bits Device Number 8bits Device ID/ Status 8 bits X Coord 8 bits Y Coord / Scan code 8 bits Checksum 8 bits Baud: 9600-baud rate (104.1 us/bit) Total bits: 64 bits Sync Bytes: Sync data bytes are used to stabilize the demodulation of the receiver side after a period of no signal input. Recommended four byte of "hex 0F". Preamble: It is used for decoder bit sync. Recommended 2 bytes of "hex 55". Device Number: 8-bits, Device number will be maximum of decimal 99, hex 63 Device ID/ Status: 8-bits Device ID: Bit 0 - Bit 2 = 000b for RF-Receiver, 001b for NMB keyboard, 010b for UEI key data, 011b for NMB Pointing device, 100b for UEI Pointing device Keyboard Status Data: Bit 3 = Reserved (0) Bit 4 = Reserved (0) Bit 5 = Reserved (0) Bit 6 = Reserved (0) Bit 7 = Battery Status (0=ok, 1= low) Pointing Device Status Data: Bit 3 = Pointing Device Left Button Status (1 = Down, 0 = Up) Bit 4 = Pointing Device Right Button Status (1 = Down, 0 = Up) Bit 5 = X coordinate sign (0 = positive, 1 = negative) Bit 6 = Y coordinate sign (0 = positive, 1 = negative) Bit 7 = Battery Status (0=ok, 1= low) X coordinate/ : 8 bits Keyboard Data = Reserved (0) Pointing Device =X-Data: 8 bits Y coordinate/ Scan code: 8 bits Keyboard Data: Scan Code (Make/Break) * Scan codes are shown in Table 2 Pointing Device = Y-Data: 8 bits Checksum: (Device Number + Device ID/ Status + Xcoord + Ycoord/Scan Code) Revision 0.1 8. 2/16/2001 Key Types All keys including the Pointing Device buttons are make/break. When a key or button is pressed, the unit will transmit the following data as shown in the protocol. For reliable data transmission, keystroke and control push buttons packets are transmitted twice wirelessly from NMB Remote Devices. MAKE 9. 8ms MAKE BREAK 8ms BREAK Stuck key Transmitter shall enable the "Stuck Key" bit and transmit it to the Receiver when a stuck key is detected after xx ms. 10. Keyboard or Remote Sleep Mode The remote devices shall enable the "Sleep Mode" bit when the Remote or Keyboard is to enter Sleep Mode. 11. Keep Alive The remote devices shall enable the "Keep Alive" bit when the user is holding a key down (not typing) for more than 70ms. 12. Resync Button Hold down the Resync button and press one of the numeric keys (1-0) to select the channel number. At this time, the 'signature ID' (Resync make code = 76hex) will be sent at the selected channel. The data format of the signature ID is the same as the key data packet described in the NMB keyboard data packet. 13. RF Power Management RF Power On Allocate Frequency Tx Data Input T1 T2 Figure 3. Timing Sequence in RF Power Management. • • 14. T1 = Power On Stable Time. Typically, it should be T1 > 5ms T2 = Frequency Stable Time. Typically, it should be T2 > 20ms Transmitter Data Input Level The transmitter data input level should be fixed as the supply voltage drops when using battery. It is required that the Input level will be Vp-p = 100mv (+/- 10%). 15. Data Coding Data coding is necessary for the wireless communication, which is to eliminate the DC offset of the demodulation caused by the series of 1's or 0's. The Manchester Coding is recommended here. Revision 0.1 16. 2/16/2001 Hardware Interface The interface to the RF-Transmitter and RF-Receiver module shall be described in the table below.

UART Interface The UART interface requires only four lines, Receive (RX), Transmit (TX), GND, and +5Vcc. The communication link will be half-duplex; meaning that each side is either a RF-Receiver or the HOST at any given time. 22.1 Protocol Format of RF-RECEIVER (UART) to the HOST. The RF-Receiver communicates serially with the Host at 9600-baud over a 4-lines connection. Data packets are exchanged over the Receive and Transmit line. The RF-Receiver only sends one make and one break code for each key pressed. After 70ms, Keep alive packet will be send until the key press is released.

Power Down In the event of Power Down, all the critical parameters and Channel Number in the RF-Transmitter and RF-Receiver unit will be save. 24. Timing Protocol Transmission of Data Packet between the RF-Receiver and the HOST must have a delay at least four byte times (about 4ms at 9600 baud) between the last byte of one data packet and the first byte of the ID code of the next data packet. There must be no more than two bytes times delay (about 2ms at 9600 baud) between the ID code and data byte(s) within a packet. 25. Set/Reset Keyboard Status Indicators Three Status indicators Num Lock, Caps Lock, and Scroll Lock can be activated or deactivated by pressing the respective keys from the transmitter keyboard. Once the HOST receives the scan code of these keys, the HOST will activate and deactivate the status of each function in the screen 26. Repeat Keys When a key is pressed and held, the make scan code is sent. After a delay of 70ms +/- 20%, the Remote Device will send a "Keep Alive Data"- packet every 70ms until the break scan code is received. 27. Device ID and Device Number When remote device has a Device ID and Device Number. Device ID shows the category of the Remote device. The following table shows the device Ids for different categories. Remote Device Keyboard Keypad Remote Control Keypad Keyboard Pointing Device Remote Control Pointing Device Device ID Table 9: Device ID and Remote Devices 12 Revision 0.1 2/16/2001 Device Number is pre-loaded in the factory before the device is shipped. The number is chosen randomly from 0 to 99. The Host will validate the received data packet by checking the Device Number is registered for that Device ID or not. After the channel synchronization, the Device Number of each remote device will be registered in the host. Note that for both keyboard and remote control, keypad and pointing device have the same Device Number. During synchronization, only Device ID of the keypad and the Device Number will be sent. The host should also register the Device Number for the pointing device of the corresponding device. 28. Channel Synchronization There are 10 channels, which are numbered from 1 to 0, to be used in the communication between the RF-Receiver and the remote devices as keyboard and remote control. For reliable data transmission, keystroke and control push buttons packets are transmitted twice wirelessly from UEI /NMB Devices. 28.1 Changing Channel of the RF-Receiver The Host using the command “Set Channel” can change the channel of the RF-Receiver. The details can be found in the section, Set Channel. Normally, the HOST will show the channel number on the screen and then wait for the reception of the signatures (i.e. Re-Sync code, 76hex, defined in Table 2) from the remote devices for confirmations. 28.2 Changing Channel of the Remote Device The channel of the remote device can be changed as the following procedure. 1. Hold down the Sync button on the device 2. Press the button on the numeric keypad on the remote device to select the channel number. At this time, the signature will be sent continuously at the selected channel until the button is released. The data format of the signature id the same as the key data packet describe in the section, NMB keyboard Data Packet. 13 Revision 0.1 29. 2/16/2001 Commands Summary The following commands that the HOST may send and their hexadecimal values.
