PC/104-Plus Two-Channel Gigabit Ethernet Card Supports Power over Ethernet (PoE)
WinSystems introduces the PPM-GIGE-2-POE. This PC/104-Plus module integrates two independent Gigabit Ethernet ports with Power Sourcing Equipment circuits. It is ideal to source two remote tethered 802.3af/at compliant PoE devices supporting up to 25W each from an external DC source.
ApplProduct Features
Implemented as a PC/104-Plus add-in I/O module, the PPM-GIGE-2-POE can manage power to remotely located PoE devices or board stacks. Both PoE interfaces can use separate external DC supplies or share a single external power source. The PoE controller for each channel goes through a detection, discovery, and classification process each time a network cable is attached or removed. The controller additionally provides input undervoltage lockout, input overvoltage lockout, over temperature detection, output voltage slew-rate limit during startup and LED status indication on each port. This protection operates automatically without the need of software.
The PPM-GIGE-2-POE is based on two Realtek RTL8110s Gigabit Ethernet controllers. These controllers combine triple-speed, IEEE 802.3-compliant Media Access Controller with an Ethernet transceiver, 32-bit PCI bus controller, and embedded memory. The Ethernet controllers are compliant with the IEEE 802.3at specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. This module uses RJ-45 connectors to plug into 10/100/1000Mbps networks using standard Category 5 unshielded twisted pair copper cables.
The PPM-GIGE-2-POE supports Windows, Linux, and other x86 real-time operating systems. This module operates over the industrial temperature range of -40°C to +85°C without a fan. It measures 3.6 x 3.8 inches (90mm x 96mm). WinSystems offers additional single and dual channel modules with or without the PoE supply.
The PPM-GIGE-2-POE supports Linux, Windows, and other x86-compatible real-time operating systems. Free drivers are available from the WinSystems' website.
