SAA CR Logger Integration Guide
May 2012 1
1. Introduction
ShapeAccelArrays (SAA) can be configured for use with a CR800 or CR1000. This is accomplished using a
Measurand “SAA232” (or “SAA232-5”) device and “SAACR1000 Integration Suite” software. The
SAACR1000 Integration Suite includes:
SAACR File Gen: a utility to create the program files that will allow the user to collect data from
the SAAs sensors; and
SAACR_raw2data: a conversion utility that converts the raw data to a format recognized by
Measurand’s SAA3D_Viewer software.
The CR1000 is advantageous for applications logging data from large amounts of various sensors.
Additionally, the CR1000 allows up to 20 SAAs to be connected at a single time (the CR800 allows for up
to 10 SAAFs connected via 2 SAA232-5s). The “Averaging in Array” (AIA) functionality in all SAAs
manufactured after March 2010 makes it possible to collect a high number of averaged samples in only
a few seconds. Arrays manufactured before March 2010 take up to 30 minutes to collect and average
1000 samples.
2. Hardware Setup
As previously mentioned up to 20 SAAs can be connected to a CR1000 logger via the 4 available COM
ports. A CR800 has 2 COM ports, thus up to 10 SAAs can be connected in the same manner. Each COM
port on the CR1000 requires a Measurand SAA232 or SAA232-5 device (Figure 2.1) to connect an SAA.
The SAA232 interface is necessary to convert the SAA’s RS485 communication protocol to the RS232
format recognized by the CR1000; in addition to providing surge protection and controlling power to the
array. The power control aids in saving power and providing SAA microprocessor resets for trouble-free
operation spanning years. A wiring diagram for connecting the SAA232 to the CR1000 and to the SAA is
located on the side of the SAA232 or SAA232-5, as can be seen in Figure 2.1. Wiring diagrams for back
panels containing CR1000, an SAAREG, and SAA232 or SAA232-5 are shown in Figure 2.2 and Figure 2.3,
respectively.
