2.5 Datalogger Compatibility
The SDM-SIO1 is compatible with our CR800, CR850, CR1000, CR3000,
CR5000, and CR9000X dataloggers. The CR5000 and CR9000X’s operating
system must be OS 6 or higher.
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() instruction.
There can be up to 15 SDM-SIO1s on a single SDM bus. Each SDM-SIO1 will
need to have a unique address before they are powered up. If other equipment
is present on the bus, whether it’s an SDM-SIO1 or not, the user needs to
insure no addresses are the same.
