www.diamondsystems.com Page 5 Overvoltage on analog input – If a voltage applied to an analog input exceeds the design specification of the board, the input multiplexor and/or parts behind it can be damaged. Most of our boards will withstand an erroneous connection of up to 35V on the analog inputs, even when the board is powered off, but not all boards, and not in all conditions. Overvoltage on analog output – If an analog ou ...
www.diamondsystems.com Page 6 2. INTRODUCTION Helios is an embedded single board computer in the PC/104 small form factor based on the DMP Vortex86DX family of all-in-one 486 processors. Helios integrates a complete embedded PC plus a full analog and digital data acquisition circuit into a single board. It is available in several models with different features: Model Processor Speed Memory Math Coprocessor Digital I/O Analog I/O H ...

I/O CONNECTORS Note: Pins marked as “key” are cut away or removed. 6.1 Input Power (J4) Input power may be supplied using either the input power connector J4, the I/O power connector J5, or directly through the PC/104 bus power pins, if a PC/104 power supply is used with the CPU. The board only requires +5VDC input power to operate. All other required voltages are generated on board. The +12V, ...
www.diamondsystems.com Page 12 6.4 Serial Ports (J8) Connector J8 provides access to the four serial ports of the Vortex CPU. The PORT1 and PORT2 ports are, independently, jumper-configurable for either RS-232, RS-485 or RS-422 protocol. Jumpers J25 and J26 are used to select the protocol. The PORT3 and PORT4 ports are fixed RS-232 protocol. All four serial ports can be independently enabled or disabled in the BIOS. The following ...

It mates with Diamond Systems’ cable number 6981004, and may be used to connect up to 2 IDE drives (hard disks, CD- ROMs, or flashdisk modules). An IDE flashdisk may also be installed on this connector to provide rugged, wide temperature solid state storage up to 4GB. Pin 20 is removed for ke ...
www.diamondsystems.com Page 17 6.13 Digital I/O (J7) Connector J7 provides 16 digital I/O lines from the Vortex CPU. These lines are buffered and have ESD protection to protect the CPU from potential damage. The buffers enable the direction to be programmed in 8-bit groups, using two additional GPIO lines from the Vortex processor. The direction may be set in the BIOS or by programming the CPU I/O control registers. DIO D0 1 2 DIO ...

www.diamondsystems.com Page 20 6.18 PC/104 ISA Bus (J1, J2) The PC/104 bus is essentially identical to the ISA Bus except for the physical design. It specifies two pin and socket connectors for the bus signals. A 64-pin header J1 incorporates the 62-pin 8-bit bus connector signals, and a 40-pin header J2 incorporates the 36-pin 16-bit bus connector signals. The additional pins on the PC/104 connectors are used as ground or key pin ...
