The KAD/SWI/107 is an Ethernet tap module designed for operating in harsh environments. All connections use copper cabling, minimum specification CAT5.
Features
- Four Ethernet ports configured as two tap ports (ingress) and two aggregator/monitor ports (egress)
- The tap port pair can be configured as either 10BASE-T or 100BASE-TX; the aggregator/monitor ports can only be configured as 100BASE-TX
- Ethernet traffic is forwarded between the ports of the tap port pair using a straight-through connection and a copy is forwarded to both of the aggregator/monitor ports
- No traffic from either of the aggregator/monitor ports is forwarded to the tap ports
- Store-and-forward operation for aggregation of tap traffic to monitor ports
- Industrial temperature operation (-40 to +85°C)
- Live at power-up (static internal routing; no MAC address learning time delays)
Applications
- Airborne network tap to aggregate data from an external aircraft 10/100BASE-TX Ethernet network
DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
The KAM/CHS/13U is a thirteen user-slot Acra KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
The NET/SWI/101 is an 8-port airborne Ethernet switch designed for operating in harsh environments. Each port is configurable for 10BaseT, 100BaseTX, and 1000BaseT link speeds or auto-negotiate over copper wiring, supporting straight-through or cross-over cables.
KAD/DSI/102 monitors the status of up to 24 differential ended discrete input channels. Each of these has an assigned programmable 32-bit counter.
The KAD/VID/106 is an H.264 video encoder card that converts one of three composite analog video inputs.
The KAD/MAT/101 allows you to run your own programs based on a dual-core C6000DSP+ARM9 microcontroller. It provides high-performance DSP functions.
KAD/ADC/136 is used to condition & digitize up to 8 analog channels.
The KAM/CHS/04L is a compact four user-slot KAM-500 chassis, which along with the housing and backplane, includes a KAM/PSU/006 power supply unit.
The KAM/CHS/03F is a compact three-user-slot KAM-500 chassis, which along with the housing and backplane, includes a KAM/PSU/008 power supply unit.
KAD/SWI/107 Ethernet Tap Module 4-Port
The KAD/SWI/107 is an Ethernet tap module designed for operating in harsh environments. All connections use copper cabling, minimum specification CAT5.
Two individual ports of the KAD/SWI/107, which together implement a tap on the Ethernet link, are referred to as a tap port pair. One of these ports is referred to as the tap port; the other port is referred to as the paired tap port. The tap port pair may be configured as 10BASE-T or 100BASE-TX and connect to the external Ethernet network. The pair of aggregator/monitor ports can only be 100BASE-TX and connect directly to an Ethernet sink device such as a NET/REC/001 or a KAD/EBM/101.
The KAD/SWI/107 provides an active non-intrusive mechanism to monitor the traffic on an external network. Traffic received on each of the tap ports is forwarded to both of the aggregator/monitor ports and the paired tap port. The traffic forwarded to both the aggregator/monitor ports is identical, which allows for the data to be simultaneously recorded, analyzed, displayed, and parsed. Traffic received on the aggregator/monitor ports is not forwarded to the tap port pair.
There is a network activity register for each tap port that counts the number of packets received through each port and the packets forwarded through the other three ports during a one-second interval. Both registers can be read over the backplane.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
