The A4FLEX features four logic inputs. Each logic input also has
two associated logic outputs, labeled as A and B.
The logic inputs are open collector inputs, and designed to be
interfaced directly with mechanical switches or 3.3V logic devices
and are 5V tolerant.

Alternatively, the logic outputs may be used in a sinking
configuration. Either the PWR link output may be used to source
a 24V supply voltage to the attached device, or an external supply
is provided up to 24V DC, while maintaining a common ground
between devices. The maximum sinking current in this
configuration is 50mA.

The logic inputs can be polled to obtain their state. However, the
A4FLEX also supports asynchronous logic event messages that

are triggered when the logic input changes state. Each input
supports an "input high" event message and an "input low" event
message. The A4FLEX can be configured to send just "input Low"
messages, just "input high:" messages or both low and high
messages.
3.5 – Factory Reset
*************************** IMPORTANT ************************
The factory reset returns the entire device to its factory
defaults. Using this feature will mean all custom settings will
be cleared.
*******************************************************************
*NOTE: The factory reset is a useful way of quickly restoring
communications with a device which has an unknown static IP
address, as a factory reset returns the device's network settings
to getting a dynamic IP. Having successfully completed a factory
reset of the device, setting the PC's IP address to also obtain a
dynamic IP address should then allow the PC to communicate fully
with that device.
The factory reset button is accessed through a small hole on the
front of the unit using a small screwdriver or a paperclip. A factory
reset is initiated by pressing and holding this button for 5
seconds or more while the device is running and then releasing
it. If done correctly, a second or two after the button is released,
all SIG indicators will turn off and the PWR, USB, NET and I/O
indicators will all turn yellow as the device reboots and it will then
go through a normal start-up procedure. If the indicators do not
change a couple of seconds after releasing the button, that is an
indication the reset button not being held long enough and the
factory reset was not applied.
Having applied a successful factory reset, on the network side,
any customized settings such as device name, stream names and
stream IP addresses, as well as receive stream assignment will all
be set back to their defaults. The device will also revert to
retrieving an IP address dynamically. The power-up defaults for
the audio settings are also cleared.
3.6 – Firmware Updates
The A4FLEX supports field firmware updates. The updates are
applied via the network using the smart firmware update tool
within the Attero Tech unIFY Control Panel. This software is
