NOTE: M879XX is based on Staco’s M779XX existing mechanical design. The PCBs used for the LED backlighting and firmware controller have been re-designed with up-to-date electronics. 12 physical function keys (vs. 10 function keys in M779XX) are now included in the rubber keypad. The environmental specifications, excluding the temperature spec, are listed here based on the similarity of mechanical construction between M879XX with M779XX.

INTERFACE CONNECTIONS
3.1
Keyboard Connection
For USB connection, the keyboard has a standard USB interface and male type A connector. It has passed the USB-IF Compliance Program for USB 2.0 standard specifications, which includes “plug and play” and “hot swappable.” The USB pin layout and schematic are illustrated in Fig. 3. Pin # 1 2 3 4 Shell
Pin Description VBUS DD+ GND Shield Fig. 3: USB Connector Configuration
Certain models of the M879 keyboard are equipped with a military style connector D38999 Series III with Type A USB as shown in Fig. 4. The part number for this connector is “USBFTV6G” (Aluminum shell with Olive Drab Cadmium plating) from manufacturer Amphenol (www.usbfield.com). The part numbers and configurations of different types of mating connectors can be found at Amphenol web site for various applications.

3.2
External USB Port (M87901 & M87921 MODELS)
The external USB port is located at the lower right corner of the keyboard (Fig. 5) This port provides a convenient way to extend keyboard functions with mobile devices, such as USB flash/hard drives, counterfeit UV detection light, and biometric reader etc. The total current consumption of the keyboard plus the external USB port device is limited to 500 mA based on standard USB specifications.

LED BACKLIGHTING
The red LED backlight is adjustable with 5 levels of dimming, plus an “off” position, by a “starburst light bulb” key located at upper right corner of the keypad. The brightness intensity cycles up each time the “starburst” key is pressed. This keyboard also has a backlight memory feature. When the keyboard is removed from the computer and plugged-in again, the initial backlight level will return to the last setting.
5.0
EMI/RFI SPECIFICATIONS (M8792X MODELS)
The M8792X models are designed with enhanced shielding for EMI/RFI applications. These models passed RE102 (Radiated Emission, Electrical Field, 10 KHz to 18 GHz) and RS103 (Radiated Susceptibility, Electrical Field, 80 MHz to 2 GHz) specified in MIL-STD-461. The test report of the scan results is available upon request.
6.0
COMPUTER SYSTEM COMPATIBILITY
With the additional USB port and superior backlighting performance, the M879 keyboard is considered as a high power device specified in the USB Compliance. The keyboard was tested in more than 30 different computers, including laptops and desktops of various manufacturers and models. However, due to the diversified hardware and software configurations in the computer industry, there is still a slight chance that the keyboard may not function properly in certain systems such as very old (> 5 years) or small form factor computers.
