The SDM-AO4 will not function correctly unless the case is
fully assembled and the case screws are fully tightened. CAUTION
5. Addressing
The SDM-AO4 is a synchronously addressed datalogger peripheral. Control
Ports 1, 2, and 3, are used to address an SDM-AO4 and send out the digital
millivolt readings for subsequent analog output. Addressing allows multiple
SDM peripherals to be connected to one datalogger.
