Bus SDA & SCL Pull-up Enable
These two switches disable/enable the cable-side pull-ups for the I²C-bus. These switches
must be ON for the MASTER Board (0) and the LAST SLAVE board in the chain. All
other boards in-between should have these switches set to OFF. If there are only two
boards connected (MASTER and SLAVE), both boards should have these switches set to
ON.
Cable Power Off/On
This switch enables the battery power connection to the RJ45 cable on pin 1 of the RJ45
jack. This allows a single power source for the complete chain of boards when all the
boards have this switch ON. Note: When this is utilized, a single bench or wall power
supply should be used, as the typical 9V battery cannot supply enough current to power
multiple boards. The 9V battery should be removed from the holder on all boards.
The input power requirements are: 6VDC to 12VDC, 100mA per board MAX.
Board Power Off/On
This switch turns power OFF/ON for the board. Board Power should be turned OFF
whenever the board is not in use, as the battery drain would result in a dead battery.
It is also recommended to remove the battery from the board when not in use to avoid
inadvertent battery drain if the OFF/ON switch is bumped ON. The battery may be
placed in the holder with the contacts “away” from each other as a storage method.
