Annex 1: Consecutive Steps in Connecting Storage Module SM4M/SM192 to PC.

Step

Action

Connect the SM192 Storage Module to the SC532 Interface using the blue SC12 cable.

Make sure the SC532 Interface is powered.

On PC, double click the PC208W Datalogger Support Software Icon.

Click the StgModule tab.

Click the SM192/SM716 tab at the top-mid of the SMS window.

Click the tab labeled ‘Setup’ to select the appropriate communication settings.

Select the COM Port settings corresponding to the serial port used by the “9 to 25” computer cable connecting

the SC532 Interface (see paragraph 3.1). In most cases this will be either COM1 or COM2.

Set Baud Rate at 19200. This is a measure of the communication speed between PC and Storage Module. In case

frequent communication problems are experienced, lower the Baud Rate and see if this solves the problem.

Click the “Connect” button to connect SM192 to PC.

Annex 2: Consecutive Steps in Retrieving Raw Data Files from SM192 Storage Module

to PC

Step

Action

Connect SM192 to PC and establish communication. See instructions in paragraph 5.2.2 or Annex 1.

Click the “Data” tab at the bottom-left.

Mark the “Comma separated” option in the File Format select box. Import of comma separated ASCII files into

MS Access has proven to be flawless and trouble free.

Mark the “Auto Increment Name” option in the Auto Name Control select box. Each retrieved data file will get a

name according to the format “DATAXXX.DAT” in which XXX is a number which automatically increments when a

new file is down loaded.

Click the file name in the File Naming Options location. A box similar to Windows Explorer appears which allows

the user to navigate to the location where he or she wants to store the retrieved data files.

Click the “Get New” button. This option collects all “new” data files from the SM192, i.e. all files not yet retrieved

in a previous down load operation. Each single SM192 data file is stored in an individual DAT file on the hard

drive.

Annex 2: Consecutive Steps in Retrieving Raw Data Files from SM192 Storage Module to PC

The above steps are discussed in detail in paragraph 5.2.3 of this manual.
