AMux 700 Data Acquisition Unit

Standards-Based Network Multiplexer Using the IRIG 106 Chapter 10 Packet and Stream Format

  • Ethernet Data Acquisition Unit (DAU)
  • IRIG 106 Chapter 10 Packet Format
  • Modular, Expandable and Flexible I/O Options
  • Gigabit Ethernet Output Interface
  • Fast Ethernet Control Interface
  • Built-in Gigabit Ethernet Switch
  • Compatible with miniR® 700 and AMux™ I/O Modules
  • Supports TCP, UDP and Multicast UDP Output Modes
  • Conduction-cooled Flight-rated Proven Enclosure

The AMPEX AMux™ 700 Data Acquisition Unit (DAU) is a network multiplexer using the IRIG 106 Chapter 10 packet and stream format. Based on the successful miniR® 700 recorder system, the AMux™ 700 DAU timestamps data received over any supported interface and creates a single network output channel over Ethernet, using either a dependable TCP/IP connection or a versatile UDP/IP packet stream. When UDP is used, the AMux™ can use multicast addressing for even greater versatility.

Configurable and Reconfigurable

Building on the modularity of the miniR recorder, the AMux™ 700 DAU base system includes the AB-003 control unit, the mR-X02 multiplex module with a dedicated timecode input, the mR-ES2 Gigabit Ethernet switch with three available ports, and an AM-801 Gigabit Ethernet output module. Additional input modules may be added — with a limit of seven to nine input modules, depending on the power and performance required of each. Time can be supplied using IRIG-B or HAVE QUICK time into the mR-X02 module, or over the network using NTP or IEEE1588 PTP. Power filter and hold-up modules are also available to meet the needs of a wide range of environments.

While achievable throughput of the system will vary depending on the number and characteristics of the inputs, the system is rated to provide a usable payload throughput of 60MBytes/sec (480Mbits/sec), limited by the capability of AM-801 output module to accurately deliver data with no loss of packets.

Data Interfaces/Format

  • IRIG-106 Chapter 10 packet format
  • Network acquisition as well as output interfaces
  • SD Video, MPEG2 and MPEG4
  • HD Video, both H.264/AVC and Motion JPEG2000
  • IntelliBus® interface
  • Variety of AMux I/O Modules: PCM, UART, Analog, and Avionics buses
Video & Imagery

The AMux 700 has been a staple in the flight test video acquisition sector for years and is also well-suited for mission system video signal acquisition. Its modularity enables as many as 8 video I/O modules or “slices” to be added to the AMux for multiple video inputs of varying types to include DVI, HD-SDI, RGB, LVDS, and SD among others. The I/O modules are added to, or removed from, the external side of the AMux 700. There is no need to crack open the “guts” of the system. The video I/O modules can also be mixed with non-video modules for acquiring other signals like 1553, ARINC 429, or PCM.  When added to an Ampex network file server, the combined system makes for a perfect pairing of data acquisition and storage for any mission system.

EW & RF Signals Data

The AMux 700 has been a staple of the flight test data acquisition sector for years, but it is also well-suited for EW mission systems. Its modularity enables as many as 8 EW I/O modules or “slices” to be added to the AMux for multiple inputs, of varying types, so the EW data and other signals can be sent to the user’s preferred storage device. I/O modules are added to, or removed from, the external side of the AMux 700. There is no need to crack open the “guts” of the system.

Flight Test

The AMux700 Data Acquisition Unit (DAU) has been a staple in flight test data acquisition for decades. With its array of acquisition modules, the AMux700 can acquire a wide variety of flight test data types and multiplex them for output in the IRIG106 Chapter 10 format.  Marrying the AMux 700 with an Ampex TuffServ network file server provides users the perfect combination of data acquisition and storage.
