The following table shows how changing the physical switch position affects the Logic In ports and
the corresponding Selector control:
Switch Position

1 High High High High Selection 1
2 High High High Low Selection 2
3 High High Low High Selection 3
4 High High Low Low Selection 4
5 High Low High High Selection 5
6 High Low High Low Selection 6

8 High Low Low Low Selection 8
9 Low High High High Selection 9
10 Low High High Low Selection 10
A set of Logic In ports configured as a binary selector is read-only. This is because the physical switch
sets the signal level of each DR4 port that it is connected to and these signals are constant for as long
as the switch is in one position.
Logic Outputs
You can configure each of the eight output ports in one of two ways:
l
Toggle: The Toggle configuration allows the state of a toggle control in the Control palette of the
Processing Workspace to control the state of the Logic Out port. When the toggle control is
unchecked, HAL sets the corresponding DR4 Logic Out port to logic high (5 V) and when the toggle
is checked, it sets the port to logic low (0 V). See the DR4 data sheet for more details on electrical
specifications for the DR4 Logic Out ports.
l
Selector: The Selector configuration allows the state of a two position selector control in the Control
palette of the Processing Workspace to control the state of the Logic Out port. When the selector con-
trol is set to the first selection, HAL sets the corresponding DR4 Logic Out port to logic high (5 V).
Conversely, when the selector control is in the second position, HAL sets the port to logic low (0 v).
See the DR4 data sheet for more details on electrical specifications for the DR4 Logic Out ports.
Analog Control Inputs
Each port allows an analog voltage source to control the value of a Level control in the Control palette of
the Processing Workspace. The input range for the port is from 0 V to 5 V, where 0 V corresponds to 0% on
the associated Level control and 5 V corresponds to 100%. The DR4 Analog Control input is protected from
voltage outside of that range up to certain limits, see the DR4 data sheet for details. Applied voltages outside
of the 0-5 V range, however, will limit the corresponding Level control to maximum or minimum, depending
on whether the applied voltage is under or over the allowed limit. For example, if you apply 6 V to the port,
