Description

The Emerald-MM-8EL-XT is a family of high performance PCIe/104 "OneBank" serial I/O modules offering 4 or 8 multiprotocol serial ports with software-controlled configuration and optional opto-isolation. An accessory microcontroller manages all port configuration and provides 8 auxiliary digital / analog I/O lines for general purpose use.

Available Models

Model # Description
EMM-8EL-XT 8-Port serial module with opto-isolation
EMM-4EL-XT 4-Port serial module with opto-isolation
EMM-8E-XT 8-Port serial module without opto-isolation
EMM-4E-XT 4-Port serial module without opto-isolation

The serial ports are based on a high speed PCIe octal UART with 256-byte TX/RX FIFOs and auto RS-485 transmit control. Each serial port can be independently configured for RS-232, RS-422, or RS-485 protocols, along with programmable 120-ohm line termination. Each port is independently isolated with an isolated power + signal chip, plus additional isolators for control signals. The board features intelligent power management that limits inrush current on power-up and also enables power-down of unused serial ports for power savings.

Opto-isolated models feature independent 2500VRMS isolation circuits for enhanced reliability in vehicle or long cable applications. All ports also feature +/-15KV ESD protection. Each serial port is available on an independent latching connector for increased isolation and ruggedness. With its wide operating temperature range and high resistance to shock and vibration, the EMM-8EL-XT fits a wide variety of rugged and on-vehicle embedded serial I/O application needs.

EMM-8EL-XT also offers 8 digital/analog I/O lines which are programmable from the on-board microcontroller. Each I/O line can be configured for digital input or output. Seven of the I/O lines can be configured for 12-bit A/D input with selectable 0-2.048V or 0-3.3V input ranges.

EMM-8EL-XT contains no configuration jumpers; all configuration and control is done with an onboard microcontroller using application software included with the product. All configuration settings are stored in the microcontroller's flash memory and are automatically loaded on power-up.

The EMM-8E family includes an on-board microcontroller to handle all configuration and control of the board's features. The microcontroller is managed with a comprehensive software suite that makes configuring the EMM-8E fast and simple. A graphical control panel, a console application, and drivers for Windows and Linux are provided to enable convenient configuration of the board and control of the I/O features in a laboratory or system assembly environment, or embedded in the customer's application software.
