I/O Ena-
ble Select the checkbox to enable the individual I/
O point. If the checkbox is not selected, that I/
O point is disabled, regardless of what other
parameters may be defined. For efficient pow-
er usage, do not enable I/O points that are not
used.
I/O Name The I/O name field is an optional text field used
to assign names to the individual I/O points for
easy reference. This name may appear in
many other screens relating to the I/O point.
I/O
Num-
ber Click on the I/O # hyperlink on the far left of the
screen to access an additional screen for I/O point
configuration. The expanded screen contains
more I/O point parameters than is displayed on
the primary page.
I/O
Selec-
tion or
Type Select the I/O type from the drop-down list. The
drop-down list includes all options available for the
entire DX80 line. Not all I/O types included in the
drop-down list are applicable for any given device.
Refer to the device data sheet to determine which
options are available for each device.
“Other” Type #: Occasionally some newly de-
signed and released devices will use I/O types not
yet listed in the drop-down list for I/O Type. When
this happens, Banner Engineering applications
engineers will supply the “other” type number. Se-
lect Other from the I/O Type drop-down list and
enter the I/O type number supplied by Banner En-
gineering into this field.
Maxi-
mum
Bad
Count The max bad count refers to a user-established
maximum count of consecutive failed polling at-
tempts before the Gateway considers the RF link
to have failed.
Poll-
ing In-
terval/
Rate To monitor network health, the Gateway commu-
nicates with, or polls, each Node to determine if
the radio link is active. The polling rate defines
how often the Gateway communicates with each
Node. Polling is always initiated by the Gateway
and only verifies radio signal communications.

I/O parameters.
Thresh-
old and
Hyste-
resis Threshold and hysteresis work together to es-
tablish the ON and OFF points of an analog in-
put. The threshold defines a trigger point or re-
porting threshold (ON point) for a sensor input.
The hysteresis value establishes how much be-
low the active threshold (ON point) an analog in-
put is required to be before the input is consid-
ered OFF. A typical hysteresis value is 10% to
20% of the unit’s range.

In the example shown graphically, the input is
considered on at 15 mA. To consider the input
off at 13 mA, set the hysteresis to 2 mA. The in-
put will be considered off when the value is 2
mA less than the threshold.
Expanded Configure Points
Most I/O point parameters are changed using the expanded view of the Configure Points tab.
