SAA CR Logger Integration Guide

Figure 2.2: Wiring diagram for CR1000 with SAA232.
An example setup using a CR1000, 2 SAA232s, and an Airlink Raven XT modem is illustrated in Figure 2.4.
If the back panel assembly and wiring has been done by Measurand, you will only need to connect the
SAA wires to the SAA232 or SAA232-5 channel. This should be done prior to connecting the power to the
logger (i.e. the 4-pin green connector on SAAREG should not be plugged in while you are wiring the SAAs
into the SAA232 or SAA232-5). The green connectors can be removed from the SAA232 for easier wiring.
When wiring the SAAs to the SAA232 and logger, make sure to note which SAA (serial number) is
connected to which SAA232 or SAA232-5 channel (if applicable), and the COM port to which the SAA232
or SAA232-5 is connected. These must match the logger program.
