Overview
SSR-500s are compact, lightweight, rugged recorders with integrated
data acquisition. The SSR/CHS/001 is an SSR-500 chassis for which a
range of plug-in modules is available, providing interfaces such as A/D
conversion, avionic bus monitoring, and video compression. Built-in
inputs include audio and IRIG-B/GPS. A rear panel Ethernet port is
provided for setup and real-time monitoring. Control is via a START/STOP
switch and an EVENT button, via external start/stop and event inputs
through the I/O connector, or SNMP commands through the Ethernet link.
Data is stored on a removable CompactFlash memory card, currently with
capacities of up to 128 GB industrial grade. A PC identifies such
removable storage as a FAT32 drive so files are instantly accessible with
no need for additional conversion software. Files are in the popular PCAP
format and are readable by the GS Works 9 display and analysis package,
as well as other third party software products.

C
The front panel is designed to be user-friendly with a clean and simple
layout. The setup software, DAS Studio 3, is streamlined for fast
configuration, with minimal time required before the system is ready to
record.

    Figure 5: Wide viewing angle When the SSR/CHS/001 is installed but is not recording data, the data rate seen by the recorder is shown on the bottom right of the display as a percentage of the 40 Mbps nominal logging speed (see the following figure). For example, if the recorder is receiving 30 Mbps, including data from modules and data from Ethernet, the display shows 75%.
