The I/O portion of a COM baseboard is divided into the following two categories.
 |
Standard System I/O |
Standard system I/O is driven from the COM CPU module itself and can include:
RS-232/422/485 serial ports |
10/100 & Gigabit Ethernet |
USB 2.0 & USB 3.0 |
VGA CRT, LVDS, HDMI, Display Port |
Keyboard & mouse |
ISA, PCI or PCIe expansion buses |
 |
I/O Added to the Baseboard |
Any I/O can be added to the baseboard. This can include your own design, third party circuits, or I/O technology from Diamond's extensive library of power and I/O circuits. Diamond's library includes:
Analog input with 12-bit or 16-bit resolution, up to 250KHz |
Analog output with 12-bit or 16-bit resolution, up to 100KHz |
Digital I/O with programmable direction & interrupt on change of state |
Relays & opto-isolated digital I/O |
Counters & timers |
Full protocol serial ports |
USB 2.0 & USB 3.0 |
10/100 & Gigabit Ethernet |
IEEE1394 Firewire |
CANbus 2.0 with opto-isolation |
GPS location tracking |
GSM/GPRS and CDMA wireless communications |
DC/DC power supply with wide input range |
Battery backup & charger circuitry |
PCIe, PCI & ISA bridges |
PCIe MiniCard & FeaturePak sockets |
Diamond Systems' application engineers work with you to bring the COM I/O you need out to connectors of your choice on the baseboard. Next we help you select from our extensive selection of proven I/O circuitry, including analog I/O, digital I/O, communications and networking to provide the specific additional functionality needed for your application.

We can include your own custom application circuitry, or, if necessary, create new logic blocks to meet your needs. Because many of Diamond Systems’ I/O logic blocks are based on reprogrammable FPGA technology, we can also provide existing FPGA code to implement many I/O functions or create new FPGA code to implement application-specific I/O requirements. As your needs change, new designs can be downloaded to the FPGA to upgrade your board without incurring engineering redesign expenses.
