Page 33: System Features
OWER EQUIREMENTS The EBX-22 requires only +5.0 volts (±5%) for proper operation. The voltage required for the RS-232 ports and analog input sections are generated with a DC/DC converter. Low-voltage supply circuits provide power to the CPU and other on-board devices. -
Page 34: Lithium Battery
LERT NTERRUPT The EBX-22 can be configured to generate an interrupt if the 5V power rail exceeds 5.25V or drops below 4.75V. These voltage thresholds conform to the power supply recommendation of 5V +/- 5%. The voltage alert interrupt is enabled in CMOS Setup on the Board tab. Interrupts available for this purpose are IRQ 3, 4, 5, and 10. -

Page 41: Sata Ports
Interfaces and Connectors SATA Ports The EBX-22 provides two serial ATA (SATA) ports, which communicate at a rate of up to 1.5 gigabits per second (SATA 1). The SATA connectors at locations J8 and J10 are standard 7-pin straight SATA connectors with friction latching. Power to SATA drives is supplied by the ATX power supply. -
Page 42: Serial Ports
RIVER ONTROL The EBX-22 features automatic RS-485 direction control for COM3 and COM4. The purpose of this function is to save the effort of RS-485 direction control in software. The direction control signal RTS is used to tri-state the transmitter when no other data is available, so that other nodes can use the shared lines. -
Page 43: Serial Port Connectors
ONNECTORS See the Connector Location Diagrams on pages 21 for connector and cable information. The pinouts of the DB9M connectors apply to the serial connectors on the VersaLogic breakout board CBR-5009. These connectors use IEC 61000-4-2-rated TVS components to help protect against ESD damage. -

VersaLogic breakout board, CBR-5009. The breakout board is connected to connector J14 of the EBX-22. The 5V power provided to the keyboard and mouse is protected by a 1 Amp fuse. This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage. -
Page 46: Usb
Interfaces and Connectors The USB interface on the EBX-22 is UHCI (Universal Host Controller Interface) and EHCI (Enhance Host Controller Interface) compatible, which provides a common industry software/hardware interface. There are six USB ports. Four standard USB Series A sockets (USB0-3) are located on the base board at locations J3, J4, J9, and J11. -

IDE interface at connector J22. The CF interface supports operation in DMA mode. The following CF modules have been tested and qualified as bootable devices by VersaLogic. Part numbers with a suffix of -3500 are RoHS-compliant. -
Page 48: Programmable Led
Push-Button Reset Connector J14 includes an input for a push-button reset switch. Shorting J14, pin 37 to ground causes the EBX-22 to reboot. This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage. A reset button is provided on the CBR-5009 breakout board. -
Page 49: Video Interface
The video interface uses PCI interrupt INTA#. CMOS Setup is used to select the IRQ line routed to INTA#. The EBX-22 uses shared memory architecture. This allows the video controller to use variable amounts of system DRAM for video RAM. The amount of RAM used for video is set with a CMOS Setup option. -
Page 50: Lvds Flat Panel Display Connector
ISPLAY ONNECTOR The integrated LVDS Flat Panel Display provided through connector J19 on the EBX-22 is an ANSI/TIA/EIA-644-1995 specification-compliant interface. It can support up to 24 bits of RGB pixel data plus 3 bits of timing control (HSYNC/VSYNC/DE) on the 4 differential data output pairs. -
Page 51: Compatible Lvds Panel Displays
The EBX-22 incorporates a High-Definition Multimedia Interface (HDMI) that supports most PC video formats, including standard, enhanced, or high-definition video on a single cable. (Audio is not supported in the EBX-22 HDMI implementation.) HDMI encodes video data into transition minimized differential signaling (TMDS) for digital transmission. Connector J24 is a standard HDMI Type A connector. -
Page 52: Console Redirection
Interfaces and Connectors ONSOLE EDIRECTION The EBX-22 can be operated without using the on-board video output by redirecting the console to a serial communications port. CMOS Setup and some operating systems such as DOS can use this console for user interaction. -
Page 53: Ethernet Interface
Interfaces and Connectors Ethernet Interface The EBX-22 features two Intel 82551ER Fast Ethernet controllers on-board. While these controllers are not NE2000-compatible, they are widely supported. Drivers are readily available to support a variety of operating systems. BIOS C ONFIGURATION Each Ethernet controller can be enabled or disabled in CMOS Setup. Ethernet interface 0 (J12) uses PCI interrupt INTC#. -
Page 54: Ethernet Connector
The EBX-22 can be configured to generate an interrupt when the temperature exceeds user-defined thresholds for CPU and board temperatures. CMOS Setup options on the Board tab are used to set temperature thresholds from 0 to 255°C. -

AUDOUTL Line-Out Left Ground Watchdog Timer A watchdog timer circuit is included on the EBX-22 that resets the CPU if proper software execution fails or a hardware malfunction occurs. NABLING THE ATCHDOG Bit D7 of the WDSET register (I/O port 1E0h) is used to enable or disable the watchdog from resetting the CPU on timer expiration. -

Page 57: Analog Input
Interfaces and Connectors Analog Input The EBX-22 analog input interface uses a 12-bit A/D converter that accepts up to eight single- ended input signals. The converter features 500 kilo-samples per second (kSPS) conversion time, with an input range of 0 to +4.095V with 4096 steps at 0.001V each. A/D input capacitance is 33 pF. -
Page 58: Binary Format (0 To +4.095V Only)
ACHINE Data Registers The EBX-22 ADC state machine uses eight 16-bit registers for analog input, at even-numbered base addresses from I/O port 1C0h to 1CEh. The state machine continuously reads ADC channels in a “round robin” fashion and places the data in the 16-bit registers. It reads the eight channels approximately 40,000 times a second. - Page 59 A/D Input Data – These bits contain the 12-bit conversion results. Bits D15 through D12 are always 0.
