2.5 Datalogger Compatibility
The SDM-SIO1 is currently supported in operating systems of the CR800/850,
CR1000 and CR3000 dataloggers. Please contact Campbell Scientific for
details of support in the CR5000 and CR9000X, which may be made available
at a later date.
3. Installation
The SDM-SIO1 is normally mounted on the backplane of a Campbell
Scientific enclosure using the screws and plastic inserts provided. The SDM-
SIO1 is designed to be installed in a dry, non-condensing environment. Before
fixing it, select and set the SDM address as this requires access to the side of
the case. The SDM address is set with a screw driver. Below is a list of the
possible SDM addresses and their relationships to the COM port number in the
SerialOpen command.
