Diamond Systems EMX-ESG777 - EmbeddedXpress Ethernet, Serial, GPIO WiFi Module

Dual Gigabit Ethernet, 6 Serial Port, GPIO EMX I/O Module

Introduction

EMX-ESG777 combines all the functionality of our EMX-ESG200 and EMX-ESG614 I/O modules into one compact board packed with I/O features. This high level of functionality offers the greatest efficiency in both size and cost for small form factor embedded systems requiring extra I/O features.

EMX-ESG777 provides 2 PCI Express gigabit Ethernet ports based on the Intel 82574IT industrial temperature gigabit Ethernet controller in the efficient EMX I/O form factor. The board utilizes two PCIe lanes on the EMX I/O connector, one for each controller, offering higher throughput compared to designs using a PCIe switch that shares one lane for both ports. Status LEDs are provided on board for both ports, and a utility connector provides access to the LED signals for use on a panel display.

The EMX-ESG777 also provides 6 RS-232/422/485 ports based on the SMSC SCH3116 industrial temperature UART in the efficient EMX I/O form factor. Ports 1 - 4 support RS-232, RS-422, and RS-485 protocols, while ports 5 and 6 support RS-232 or TTL mode. In RS-232 mode, ports 1-4 offer TX, RX, RTS, and CTS signals, while ports 5 and 6 offer TX and RX only. All ports feature programmable bad rates up to 921,600 in all protocols.

EMX-ESG777 includes 14 digital I/O lines for general purpose application. Each line has individually programmable direction, and all lines offer ESD protection for increased reliability.

For applications requiring GPS functionality, EMX-ESG777 can be fitted with the Trimble Condor C2626 GPS receiver offering up to 5Hz update rate, NMEA communications protocol, and PPS timing output. An on-board backup battery maintains the GPS almanac for faster acquisition after power-up.

Wide range -40ºC to 85ºC operating temperature and fully latching I/O connectors provide appropriate ruggedness for vehicle and harsh environment applications. Ethernet drivers are included for Windows Embedded Standard 7, Windows CE 6, and Linux 2.6.

The New EMX Standard

EmbeddedXpress (EMX) is a new generation, highly efficient embedded form factor designed to provide an efficient solution for PCI Express I/O expansion in a rugged, low-cost, small format. EMX is optimized for use with COM Express and QSeven based systems and is an ideal choice for providing I/O expansion in off the shelf and custom embedded systems using these and other COMs. EMX also works with single board computers in the EMX Basic and Compact form factors such as Diamond's Altair EMX single board computer.

EMX SBCs come in two sizes: 95x95mm "Compact" and 95x125mm "Basic". All EMX I/O modules are in the Compact format. These sizes match the sizes of COM Express Compact and Basic modules, providing a perfect fit that enables the development of both COM Express / QSeven baseboards and single board computers in the same physical form factor.

The EMX expansion bus provides 4 lanes of PCI Express x1 connectivity along with USB, SATA, and LPC. This broad range of high speed and pin-efficient buses provides enhanced flexibility for designers of SBCs and I/O cards, allowing access to a wider range of peripheral chips and functionality, while conserving precious space on the PCB through the use of a compact, low-cost, stacking bus connector. The EMX bus also contains ample reserved pins, providing a path to future bus technologies to retain its longevity well into the future.

Key Highlights of the EMX Form Factor:

  • Compact, rugged form factor offering stackable I/O expansion 
  • Optimized for use with COM Express and QSeven COMs 
  • Low-cost, small I/O connector uses less PCB area and provides more room for I/O connectors
