ships with AC adapter but, in addition, offers the option of a remote power /

field cable (item number 14020) to facilitate connection to datalogger power

for the SC532A and the Storage Module where 120 VAC is not available.

5.1.2 Via Datalogger

The Storage Module is linked to the CR500/510, CR10/10X or CR23X by the

SC12 cable. The computer connection is via an SC32A (Figure 5-2), SC929 or

SC532(A)/RAD modem interface. For this configuration with the CR23X,

connect all devices to the 9 pin CS I/O port. Select the “Via Datalogger”

option in SMS and select the appropriate datalogger and baud rate.

Please note that communication in this mode is limited to a maximum speed of

9600 baud (19200 on the CR23X), which can make the transfer of large

volumes of data a lengthy process, compared to direct connection to a PC

where baud rates up to 115200 are supported.

The SC32A internal SDM blocking jumper should be in place. Without the

jumper in place (and sometimes with the SC929/RAD), Windows may report a

“framing error” after correctly collecting data with SMS.

Communication between a PC and Storage Module can also take place via the

CR23X when the computer RS232 is connected to the CR23X RS232 and the

Storage Module is connected to the CS I/O port (Figure 5-3). This

configuration allows baud rates of 19200 and 38400.
