Instruction manual

CSM1 Card Storage Module

1) While performing the power up tests, the 'Write' LED will

normally flash for a short period, before the status indicator

flashes. This is caused by the CSM1 checking that it is able

to write to the card.

2) It is important that the SC12 connector is plugged into the

CSM1 and also into the SC532(A) or datalogger, with the

connector held perpendicular to the end of the case. If you

force the connector in at any other angle, the CSM1 may not

perform its power-up status display, although normally it

will still be able to store data. However, if the CSM1 does

not flash the status LED on power-up, it is advisable to

unplug, wait five seconds and plug it back into the

datalogger to ensure there has been a good connection.

3) If you experience problems in communicating with a CSM1

when using a PC201 card, please refer to Appendix B of the

CSMCOM manual for possible address problems and

Appendix A of this manual for details of possible problems

with the PC201 power supply.

4. Storing Data

The CSM1 emulates Campbell Scientific's SM192/716 Storage Modules for

most aspects of data storage. Therefore the same basic programs and

procedures are used to store data in the CSM1. Details of how to store data for

each datalogger type are given below.

4.1 CR10

Write your program as normal, including instructions to store data to Final

Storage. Include Instruction 96 to store data to a Storage Module, after the

output instructions. The CSM1 has a fixed address of 1 so the first and only

parameter for Instruction 96 is 71 (see Table 2 for an example program).

Under the control of the program shown in Table 2, the CR10 makes a Module

temperature measurement (in °C) and a thermocouple measurement (converted

to °F) every 5 seconds. Every hour, the output flag is set and the Day, Hour

and Minute as well as the hourly averages for the two temperatures are sent to

Final Storage. Following this, the same data is sent to the CSM1, if present.

If the CSM1 is not present, the data is backlogged for later transfer.

If you are using older versions of EDLOG to develop your program, entering

the code 71 for Instruction 96 will only display SM192/SM716 as the output

option. Using parameter 71 will still work with the CSM1.
