Page 4: Ethernet Connector (Lan1)
MAIN POWER INPUT CONNECTOR (PWR1) Input power may be supplied either through this connector, the I/O power connector, or directly through the PC/104 bus power pins. Pegasus requires only +5VDC input power to operate. However since the PC/104 bus includes pins for +3.3V and ±12V, these voltages may be supplied through this connector if desired. Also if a 3.3V LCD is used, then 3.3V must be supplied through this power connector. Multiple +5V and ground pins are provided for extra current carrying capacity if needed. Each pin is rated at 3A max. For applications requiring ... -
Page 5: Serial Port Connector (Com1)
SERIAL PORT CONNECTOR (COM1) This connector provides access to the 2 serial ports from the CPU chip. Port 1 is RS‐232 only and Port 2 may be jumper‐configured for RS‐232, RS‐422 or RS‐485 protocols. In RS‐422/485 mode, the port may have a jumper‐selectable 120‐ohm termination resistor across the RX pins and jumper‐selectable pull‐ up/pull‐down resistors on the TX/RX lines. The RX resistors are configured so that the port reads back a 0 when it is open circuit.

- Page 10 POWERING ON PEGASUS Follow these steps to power on and verify the functionality of the Pegasus SBC. This process assumes you have a Pegasus SBC and cable kit. 1. Connect a VGA monitor to the SBC. Attach the VGA cable, 6981084, to the VGA connector on the SBC and connect your monitor VGA cable to the DB9 socket. 2. Connect a keyboard and mouse to the SBC. Attach the PS/2 Keyboard/Mouse cable, 6981162, to the PS/2 connector on the SBC and connect your keyboard and mouse devices to the connectors on the other end of the cable. 3. (Optional for USB Keyboard/Mouse) If you are using a USB keyboard and mouse, attach the USB cable, 6981171, to the USB0‐1 connector on the SBC and connect your keyboard and mouse devices to the connectors on the other end of the cable. 4. Connect an external IDE hard drive or CD device to the SBC. Attach the IDE ribbon cable, 6981004, to the IDE/Flashdisk connector on the SBC and connect your IDE device to the connector on the other end of the cable. Note: you must provide an external source of power for your IDE device. 5. (Optional for USB storage device) If you are using a USB storage device, attach the USB cable, 6981171, to the USB0‐1 (USB2‐3 if using a USB keyboard and mouse) connector on the SBC and connect your external storage device to the USB0 (USB2 if using a USB keyboard and mouse) connector on the other end of the cable. 6. Connect the SBC to power. Attach the Power In cable, 6981175, to the Power In connector on the SBC. Ensure your +5V power source is off. Connect your +5V power source to the other end of the cable. 7. Turn on the power source. The Pegasus BIOS screen should appear and then the SBC should begin booting from the external storage device. ...

- Page 12 CONFIGURING IDE DEVICES The on‐board PCI IDE connector supports two IDE devices: a primary master and a primary slave. The supported IDE devices include the on‐board flashdisk, a CompactFlash disk, a flashdisk plug in module on the IDE connector, or external IDE devices. You can configure the system’s IDE devices from the BIOS’s Standard CMOS Features screen. Many devices have on‐board jumpers for configuring itself as a master or slave. Consult the device’s User Manual for details. The possible IDE device combinations for the two Pegasus models are as follows: Master Device on IDE Connector CompactFlash Disk The 2GB on‐board flashdisk on Pegasus model PGS800‐256‐2G is fixed as the primary slave device and defaults to drive C: if no other bootable device is found. If a bootable device is found as the primary master, the on‐board flashdisk is assigned drive D:. This model does not allow for devices on the IDE connector and a CompactFlash disk to co‐exist.
