GPIO-MM Digital I/O Module
PC/104

GPIO-MM is a PC/104 digital I/O module based on an FPGA, allowing multiple feature sets to be implemented on the same hardware platform. The FPGA is a Xilinx Spartan 2 RAM-based device with 200K gates (XC2S200). An on-board configuraton flash memory device stores the FPGA code for automatic loading on power-up, and new code can be downloaded using a JTAG cable connected to a PC. Several standard off the shelf personalities are available, and custom ones can be developed either by users with Xilinx tools or by Diamond as a customization service.

The right side I/O connector includes ESD protection circuitry for increased reliability, while the left side I/O connector offers high-drive logic buffers for increased load compatibility, along with jumper-configured pull-up / pull-down resistors. All digital I/O pins are set to input on power-up to avoid conflicts with external circuitry.

GPIO-MM-12 Digital I/O Module
PC/104

GPIO-MM-12 is part of a family of reconfigurable digital I/O and counter / timer modules with various port and pin configurations. Each board uses identical hardware with a 200K gate Xilinx Spartan II RAM-based FPGA. The varying configurations are based on different FPGA code. The FPGA code is stored in a flash memory on the board, enabling GPIO-MM-12 to be reprogrammed in the field with different designs, including custom designs.

The GPIO-MM-12 configuration provides 48 digital I/O lines and 10 programmable counter/timers. The counter/timer features are based on our legacy Quartz-MM board, while the 48 digital I/O lines are compatible with our legacy Garnet-MM board. This configuration combines the features of both these boards into one board to reduce your PC/104 stack size and cost.

Other GPIO-MM configurations provide up to 96 digital I/O lines.

The FPGA code is stored in a flash memory on the board, enabling GPIO-MM-21 to be reprogrammed in the field with different designs, including custom designs.

The GPIO-MM-21 configuration provides 96 digital I/O lines. 48 lines are buffered. The 96 digital I/O lines are compatible with our legacy Garnet-MM and Onyx-MM boards. This configuration combines the features of two 48-line digital I/O boards into one board to reduce your PC/104 stack size and cost.

Other GPIO-MM configurations provide 48 digital I/O lines with 10 16-bit counter/timers.

Digital I/O Features

The digital I/O includes 96 programmable-direction lines using four 8255 cores. 48 of the I/O lines are buffered for enhanced output current. All I/O lines contain jumper-selectable 10Kohm pull-up/pull-down resistors. 48 I/O lines are contained on each of two 50-pin connectors, along with system ground and a convenient +5V power pin. Both I/O connectors provide the digital I/O lines in ABC port order.

Miscellaneous Features

The board requires only a +5V input and operates from -40°C to +85°C. All board functions are supported by our Universal Driver software for Linux, Windows 2000/XP/CE, DOS, and QNX.

Onyx-MM Digital I/O Module
PC/104

Extensive software control of features is the highlight of this digital I/O module featuring 48 digital I/O lines, 3 16-bit counter/timers, and 3 independent PC bus interrupt inputs.

The 48 digital I/O lines on Onyx-MM are based on 2 82C55 ICs. They can be programmed for input or output in groups of 8 lines. Direct as well as strobed (latched) I/O modes are supported, and all I/O lines are connected to 10K Ohm pull-up resistors.

The 3 16-bit counter/timers are based on an 82C54 IC. They are controlled through a configuration register on Onyx-MM (in addition to the standard 82C54 configuration register). The counter inputs can be switched between external signals, the on-board 4MHz clock oscillator, or counter outputs, all under software control. By using one counter’s output as another counter’s input, you can cascade counters in software to create a 32-bit or 48-bit counter.

Onyx-MM also features programmable interrupt operations. A second software-controlled register on board configures up to 3 interrupt lines on the PC bus. Interrupts can be generated by the counter/timer outputs, digital I/O lines, or an external input line. This allows you to use a counter to generate bus interrupts at a programmed periodic rate, generate hardware interrupts under software control, or generate interrupts in response to an external event.

Onyx-MM-DIO Digital I/O Module
PC/104

DIf you’re looking for a basic 48-line digital I/O PC/104 module, then Onyx-MM-DIO is what you need. This module is the same as our Onyx-MM digital & counter/timer module but without the counter/timer and interrupt circuitry. This board still has the quality and attention to detail of our other modules, such as: 10K Ohm pull-up resistors on all I/O lines; all ports reset to 0 on power-up or system reset; connector pinouts compatible with our other digital I/O boards; and free software.

The 48 digital I/O lines on Onyx-MM-DIO are based on 2 82C55 ICs. They can be programmed for input or output in groups of 8 lines. Direct as well as strobed (latched) I/O modes are supported, and all I/O lines are connected to 10K Ohm pull-up resistors.

Opal-MM-1616 Opto In + Relay Out Module
PC/104

Opal-MM-1616 is a PC/104 format digital I/O module designed for industrial applications requiring isolation between the computer and the external signals it is monitoring and controlling.

The Opal-MM-1616 features 16 optoisolated digital inputs and 16 relay outputs. Each input has an input range of 0-30VDC. Opal-MM-1616 can be configured to generate an interrupt when any input changes state. Either or both banks of 8 inputs can be configured for interrupt operation. One 34-pin I/O header is used for the optoisolated inputs.

The 16 relay outputs are SPDT format (form C). Each relay has 3 contacts: Common, Normally Open, and Normally Closed. For safety and reliability, all relays are at their power-off state at power-up or system reset. Each relay can switch both AC and DC voltages. Two 26-pin I/O headers are used for the relay outputs with 8 relays on each pin header. The relays have long lifetime (10,000,000 operations) and quick actuation time (5ms max operate and release, break before make).

Diamond Systems’ Universal Driver software provides drivers and example code for use with the Opal-MM-1616. The software provides support for interrupts and enables you to integrate you own code that is called when an interrupt occurs.

Note: The maximum component height on this board is .492″, slightly higher than the PC/104 standard of .435″. This extra height will usually not be a problem unless the board stacked directly above the IR104-PBF has components mounted on the bottom of the board or through-hole pins that exceed .043″ in height. In this case you can mount the IR-104-PBF on the top of the stack.
