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 COMport number in the
SerialOpen command.
There can be up to 15 SDM-SIO1s on a single SDM bus. Each SDM-SIO1 will
need to be set to a unique address before they are powered up; if any other
equipment is present on the bus, whether it’s an SDM-SIO1 or not, then the user
will have to ensure their addresses are not the same.
