1. 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.

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.

4. Power-On-Reset
The wireless Keyboard with Pointing Device will generates a "power-on-reset" when power is first applied
to the unit. 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.

8. 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 8ms MAKE BREAK 8ms BREAK
9. 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.

• T1 = Power On Stable Time. Typically, it should be T1 > 5ms
• T2 = Frequency Stable Time. Typically, it should be T2 > 20ms
14. 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.

Serial data is processed using SDA, SCK, LE pins of the RF-Module for the Transmitter and the Receiver.
Binary serial data is entered through the SDA pin. One bit of data is shifted into the shift register onto the
rising edge of the clock (SCK). When the load enable (LE) pin is high, stored the data latched. After the
two 19-bit register being latched, the frequency will be locked.

23. 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 Device ID
Keyboard Keypad 1
Remote Control Keypad 2
Keyboard Pointing Device 3
Remote Control Pointing Device 4
Table 9: Device ID and Remote Devices
Revision 0.1 2/16/2001
13
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.

39. Change Device Number
• Press “Re_sync + Fn” and held down for 3 seconds, then enter 2- digits Device Number 0-9.
40. Select Device Channel Number.
• Press “Re_Sync” and held down, then enter Channel Number 1 or 2, 3, 4, 5, 6, 7, 8, 9, 0.
40. Test Mode
• Channel testing. Transmitter channel must default to channel 1.
Press “1 + 3 + C” and held down for 6 seconds and release, Ten channels will be tested and
after the testing, the channel number will return to default channel.
• Frequency testing.
Press “1 + 3 + F” and held down for 6 seconds and release. The device channel frequency
can be measured by using spectrum analyzer. Pressing “F4”, the transmitter will transmit
“one and zero” continously. Pressing “F3”, the transmitter will exit on frequency testing.
