The MDAU-1553 is a miniature bus data acquisition unit for capturing 8 channels of bulk and selected MIL-STD-1553 data.

Selected data can be captured at up to 40 Mbps and inserted into a PCM format. This PCM format can be multicasted over Ethernet and transmitted as a traditional clock/data PCM. Simultaneously, 100% of the MIL-STD-1553 data can be bulk captured and transmitted over the dual 1 GbE Ethernet ports as multicast packets. Ethernet data can be encoded using IRIG-106 Chapter 10/11, IRIG-106 TmNS Chapters 21-26, or DARv3 encapsulation. Additional status and performance information is also available for insertion into the PCM format or transmission over Ethernet.

The MDAU-1553 consists of the MHDM-553-1 module which perform the actual acquisition of the 1553 data, the MOVH-700-1 overhead processor/FPGA module set, and a 60 W power supply module.

In addition to operating as a standalone 1553 data acquisition device, the MHDM-553-1 module can also be used with any MnACQ-2700 data acquisition system. The MHDM-553-1 module occupies the high data rate (HDR) module slot directly above the MOVH-700-1 module.

In this configuration, any of the over 200 standard MnACQ compatible modules can be used to capture selected data while the MHDM-553-1 captures bulk and selected MIL-STD-1553 data. The selected data from the standard modules and the MHDM-553-1 can be combined into a shared PCM Format. Up to 20 Mbps, the data can be mixed freely. From 20 Mbps to 40 Mbps, the data must be split 50/50 between standard module data and MHDM-553-1 data.
