Address F is not available as it is the broadcast address. Setting this address will result
1
in the SDM-SIO1A having an address of 0 rather than F.
Connection to the SDM-SIO1A is achieved via the 11 terminals arranged along
the top of the unit. The terminals are spring loaded providing an easy and
reliable method of connection. Strip wires 7 to 9 mm and twist. Open the clamp
by pushing the orange tab down with the tip of a small flat-blade screwdriver
and insert the wire into the round hole. Release the clamp and verify the clamp
grips the wire rather than the plastic insulation.
If there is a need to insert more than one wire in each terminal, if using multi-
strand wire, twist the conductors together first. If using solid wires, solder or
crimp multiple pairs together before insertion.
TABLE

shows all the connections on the SDM-SIO1A.
