The KAD/IBM/101 is a two-channel serial bus monitor for up to two IMB busses.
Features
- Monitors up to two IMB busses
- Coherently parses traffic (up to 65 words) and tags for up to 1024 messages (including one catchall slot) per bus
- Aperiodic transmission of packetized IBM messages including tags as iNET-X parser aligned payload structure per channel
- Message counter per bus
- Pass-through output per bus
Applications
- IMB bus monitoring and recording
The KAD/BCU/140 is a full-duplex Ethernet Acra KAM-500 backplane controller, programmer, and IPv4 packet generator with a link speed of 100BASE-TX.
The KAM/CHS/09U is a nine-user-slot KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
KAD/IBM/101 2 Channel IMB Serial Bus Monitor
The KAD/IBM/101 is a two-channel serial bus monitor which combines the capabilities of a coherent message parser with the flexibility of an iNET-X packetizer on a single module.
The parser parses up to 1024 messages per channel and their associated time and status tags. Each message has a stale bit (word read before), skipped bit (buffer overwritten), and empty bit (no message received since power-on). Intermodule Data Bus (IMB) messages can be parsed based on the 16-bit Label field in each IMB message. Each parser slot can hold a message of up to 65, 16-bit words long.
Every message received from each of the two busses is captured and packetized—along with the time tags and a bus tag—with other received messages in a packetized buffer. The packetizer contents can be assembled into Ethernet frames by an iNET-X controller or transmitter, for example, the KAD/BCU/140, for transmission over Ethernet
To ensure efficient use of the bandwidth, iNET-X packets are only generated once a payload threshold has been reached. Additionally, a programmable timeout ensures that smaller packets are generated even during periods of low activity on the bus, thereby allowing real-time analysis and processing of the acquired messages. When there is no traffic, no packets are generated. Both channels have outputs and therefore are not end-terminating nodes. All IMB messages received at each channel are re-transmitted in a passthrough fashion.
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.
