CSM1 Card Storage Module

2.2 Card Types Supported
The CSM1 supports JEIDA 4, PCMCIA standard memory cards. Sizes of
256K to 2M are supported (256 bytes reserved for system use). Low resolution
data format requires two bytes per data value with high resolution data
occupying four bytes. Datalogger programs require the space as stored on disk,
plus an overhead of approximately five bytes.
Standard card sizes are 256K, 1M and 2M. These equate to low resolution data
capacities of 130944, 524160, and 1048448 locations respectively. (Please
contact Campbell Scientific to check on the preferred card size and
availability.)
CSM1 operation cannot be guaranteed with cards not tested and
supplied by Campbell Scientific.
2.3 Compatibility with SM192 and SM716 Storage Modules
Unlike the SM192/716 Storage Modules the CSM1 does not support *9 Mode
commands for the CR10 datalogger. Also it does not support remote
communications via a CR10 datalogger.
The module address is fixed at 1. Therefore only one CSM1 can be connected
to a CR10. However, additional SM192/716 modules can be attached at the
same time as a CSM1, providing their addresses are not 1.
