PC/104-Plus board embeds gigabit
Ethernet
Winsystems has developed a PC/104-Plus-compliant module based on the Intel 82541ER Ethernet controller.
In response to customer demands for high-speed connectivity for industrial embedded applications, Winsystems has developed a PC/104-Plus-compliant module based on the Intel 82541ER Ethernet controller Designated the PPM-Gigabit, it is designed to offer flexible, high-performance Ethernet networking capability at 1000Mbit/s datarates

Embedded module takes acquisition onboard
Winsystems reckons the PCM-ADIO is the most flexible PC/104 industrial data acquisition module on the market, combining all the key elements of a total data acquisition system on a single board.
The PPM-Gigabit emulates the popular Intel Pro/1000 PCI board.
This board and its Ethernet controller are well supported by a wide range of operating systems including Linux, Windows CE and XP, FreeBSD and DOS.
The PPM-Gigabit module incorporates an Intel (Sunnyvale, California) fifth generation 82541ER integrated Ethernet controller.

Board embeds four high-speed USB ports
The PPM-USB2 is a high-speed four-port PC/104-Plus Universal Serial Bus 2.0-compliant (USB2.0) module.
It has a direct 32bit PCI interface to the bus and supports 10, 100, and 1000Mbit/s data transfers in both full- and half-duplex environments.
The controller handles the gigabit traffic with low network latency and minimal internal processing overhead.
The module will auto-detect and configure itself to the speed of the link partner.
It incorporates the latest DSP architecture that implements digital adaptive equalisation, echo cancellation, and crosstalk cancellation to improve performance in noisy environments.
It will also support two-pair and three-pair cable downshift.
The controller is designed to have independent transmit and receive queues to limit PCI bus traffic, and a PCI interface that maximises the use of bursts for efficient bus usage.
The PPM-Gigabit module is fully PC/104-Plus-compliant supporting increased bus throughput necessary for higher-performance networking systems.
Multiple PPM-Gigabit boards can be installed on a PC/104-Plus stack if additional Ethernet connections are required.
Each PPM-Gigabit is shipped with an EEPROM that contains the configuration information describing the device architecture, address, interrupts etc.
Use of the EEPROM allows the board to be configured solely by the software offering a user-friendlier Ethernet adapter.
An industry standard RJ45 connector is onboard to allow an easy and direct interface to the network using standard Cat5 twisted copper cables.
LEDs provide a visual indication as to the status of the link and network activity and speed.
The module measures 90 x 96mm and weighs only 84g.
The PPM-Gigabit requires only +5V at 270mA (1.35W).
It will operate from 0 to +70C.
Delivery is from stock to three weeks.
List price for the PPM-Gigabit is $249.
