Product Sheet

The KAD/UBM/104 is an eight-channel serial bus monitor which combines the capabilities of a coherent message parser with the flexibility of an iNET-X packetizer and an error-detection function, on a single module.

Features

  • Monitors up to eight of any one of Actuator Bus Interface (ABI), Actuator Control Equipment-Cross Channel Data Link (ACE-CCDL), or Actuator Control Bus (ACB) busses
  • Coherently parses traffic and tags for up to 256 messages
  • Bit-rates of 1,000,000 bps
  • Aperiodic transmission of packetized data
  • Detects message errors

Applications

  • ABI, ACE-CCDL, or ACB bus monitoring and recording

KAD/UBM/104 8 Channel Serial Bus Monitor Parser

The KAD/UBM/104 is an eight-channel serial bus monitor which combines the capabilities of a coherent message parser with the flexibility of an iNET-X packetizer and an error-detection function, on a single module.

The module operates in ABI, ACE-CCDL, or ACB bus monitoring modes. The parser parses up to 256 messages and their associated time and status tags. Each message has a stale bit (word read before) and skipped bit (buffer overwritten). ABI messages can be parsed based on their bus number, frame preamble ID and/or address fields. ACB messages can be parsed based on their bus number, message request function code, and starting address.

Every message received from each of the eight 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, the packets are only generated once an iNET-X payload size 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.

 

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.
