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
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.

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.
