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
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.
