The MACQ-600-1 is a high-speed overhead module for use in the MnACQ-2000-1 stacks. The module enables the stack to operate as a wideband stand-alone data acquisition unit at up to 20 Mbps. The MACQ-600-1 IEEE-1588 time and Ethernet interface and Remote bus (R-bus) module include a Field Programmable Gate Array (FPGA) that performs 1588 time synchronization and implements the analog overhead. It converts PCM analog acquisition data into IP packets that are sent to the Ethernet network for recording and distribution. Its 100BASE-T Ethernet port is used for data acquisition setup, configuration, and transport and for stack SNMP status and control.

The MACQ-600-1 data resolution is 16 bits per word and information about the module is stored in onboard non-volatile memory. Configurable parameters (using XML files or TTCWare) include IEEE-1588 PTP information and data formatting and transmission specifics.
