Basic Module Setup
This page discusses how the module should be set up
including dip switch positions.
The dip switches on the I/O and AC detector modules must be
properly configured for the LOGGER to operate and for it to be
On the AC Detector module Switch 1 must be down (off position). Switch 2 should also be down
to select I2C address 0x77. If switch 2 is up address 0x76 is selected.
Address 0x76 is also used by the pressure/temperature/humidity sensor.
(Two edge detectors are allowed if no pressure/temperature/humidity
sensor is connected.)
On the I/O Expander module switch 1 must be down. Switch 2 should
also be down to select I2C address 0x75. An I/O expander at
address 0x75 supports pulse counting on the first 8 I/O pins and
simple I/O on the other 8 pins. If switch 2 is up I2C address 0x74
is selected which provides 16 channels of simple I/O pins. Two I/O
Expander modules are allowed for a total of 32 I/O pins.
