Emerald-MM-8PL
8-Channel, Software Programmable PC/104 Serial Port Module
Emerald-MM-8PL offers 8 multi-protocol serial ports on a single PC/104 module with complete software configurability via the operating system. Each port can be individually selected for RS-232, RS-422, or RS-485 under software control. Both local-echo and non-local-echo modes are supported for RS-485. I/O addresses and interrupt levels are also programmable, with interrupt sharing available for any number of ports. Each port may further be enabled or disabled in software. All configuration data is stored in an on-board EEPROM that is loaded automatically on power-up.
For applications where fixed addresses are desired, four groups of preset addresses are available with jumper settings that override the programmed settings. Line termination for RS-422/485 modes is also jumper-selectable.
Emerald-MM-8PL offers 8 convenient digital I/O lines. The direction of each line is independently programmable. Diamond’s Universal Driver software provides software support for these digital I/O lines.
Two I/O headers are provided, with four serial ports and four digital I/O lines on each header. The board operates on +5V only, eliminating the need for a +12V supply that is often required for serial port operation.
Emerald-MM-8PL is based on the industry-standard 16C654 quad serial port IC. Two ICs provide a total of 8 serial ports. Each port contains 64-byte transmit and receive FIFOs to support the high-speed 115.2kbps data rates. Drivers are available for a wide range of operating systems including Windows 10 and Linux.
Note to existing customers:
Emerald-MM-8PL is a form-fit-function replacement for our previous product Emerald-MM-8P (EMM-8P-XT) with the single exception that the maximum RS-232 data rate is limited to 115.2Kbps vs. 460.8Kbps on EMM-8P-XT. This change is due to the end of life of the RS-232 transceiver used on EMM-8P-XT. Except for this component, all other components and the PCB are the same between the two boards.
Emerald-MM-Opto
2 or 4-Port RS-232/RS-422/RS-485 PC/104 Module
Emerald-MM-Opto provides an integrated, rugged, and reliable solution for PC/104-expandable embedded systems requiring serial communications in demanding applications. It offers 2 or 4 optically isolated serial ports with RS-232, RS-422, and RS-485 protocols, as well as 24 digital I/O lines, all on a single board.
Optical isolation of 1000V DC or AC protects your embedded system from ground differentials or noise spikes that would damage non-isolated boards. Each port is isolated from the other ports as well as the system. Extended temperature capability (-40 to +85ºC) enables the board to operate in vehicles such as trains and buses without concern for temperature swings. These features enable Emerald-MM-Opto to provide reliable serial communications in harsh environments such as trains and buses.
In addition to ruggedness, Emerald-MM-Opto offers flexibility and advanced features. Each serial port is independently configurable for protocol and IRQ settings. Eight different I/O address combinations are built in. The 16C2850 UART chips with 128-byte FIFOs support high-speed data rates at up to 460kbps without overloading the system processor. Auto-flow control enables easy RS-485 operation by automatically enabling and disabling the transmitter during data transmission, to prevent bus conflicts or excessive software overhead.
Emerald-MM-Opto also offers multiple termination methods on the serial ports to support varying interface requirements. In RS-422 or RS-485 networks, termination resistors are normally installed at the endpoints of the cables to minimize reflections on the lines. The board provides jumper-selectable termination and pull-up/pull-down resistors for this purpose. The sensible jumper positioning and layout help simplify board configuration and minimize confusion.
The 24 digital I/O lines are based on an 82C55 chip and feature programmable direction in 4- and 8-bit groups. All I/O lines contain user-configurable 10K Ohm pull-up resistors for convenience. This 2-in-1 combination of serial ports and digital I/O can help lower the size and cost of your embedded system by eliminating one additional board from your PC/104 stack.
Diamond Systems offers appropriate mating cables for your convenience. Cable no. C-DB9M-1 provides a DB-9 male connector with standard PC serial port pinout. Each serial port requires one cable. Cable no. C-26-18 is a 26-conductor ribbon cable for the digital I/O lines.
Emerald-MM-4M-XT
4-Port RS-232/RS-422/RS-485 PC/104 Module
The Emerald-MM PC/104 module gives you 4 serial ports operating at speeds up to 115kbps. In RS-232 mode, the full complement of standard PC serial port signals (8 signals + ground) are provided for each port and are grouped onto two 20-pin headers (2 ports per header). In RS-422 mode, Signals RX+, RX-, TX+, and TX- are provided, along with ground. In RS-485 mode, signals TX+/RX+ and TX-/RX- are provided, along with ground.
5V-only operation and −40°C to +85°C industrial operating temperature range are standard features. The industry-standard 16C554 UART is compatible with all popular embedded operating systems.
Flexible Configuration
Emerald-MM offers more interrupt level and I/O address options than other quad serial port modules. Therefore, integrating the board into your computer system is a simpler task. Eight different I/O address combinations and 10 different interrupt levels are available.
Interrupt Sharing
To help conserve ISA bus interrupts, any number of ports can share the same interrupt level. If you have two boards in one system, both boards can share the same interrupt level as well. An interrupt status register is provided to indicate the status of each serial port’s interrupt request signal.
Interrupt Configuration
Interrupt levels are individually selectable for each port. The available interrupt levels are 2, 3, 4, 5, 6, 7, 10, 11, 12, and 15. In addition, a 1K Ohm pulldown resistor is provided for each port.
A single interrupt level can be shared by 2, 3, or 4 ports on one board and can even be shared by more than one board in the system. To enable interrupt sharing, set two or more interrupt level jumpers to the same level and pull out all but one pulldown resistor jumper.
GPIO-MM
Reconfigurable 48-line Digital I/O + Counter/Timer PC/104 Module
GPIO-MM 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 to be reprogrammed in the field with different designs, including custom designs.
The GPIO-MM 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.
Onyx-MM
Programmable Counter/Timer, Interrupt, and Digital I/O PC/104 Module
Extensive software control of features is the highlight of this digital I/O module featuring 48 digital I/O lines, 3x 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 counters output as another counters 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
Low-Cost 48-Line Digital I/O PC/104 Module
If you are 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.
