User Assigned Colors
This field specifies which color is assigned to a relay for a given state. The choices are “RED/GREEN” or “GREEN/RED”.
The colors may indicate different states depending on the physical wiring to the uSwitch.
Power On State
This dropdown box configures the initial power on state of the relay when a uSwitch is first turned on. The options are
OFF, ON and LAST
. (In Watchdog Mode the Relay Power On State Must be Programmed to “OFF”)
1. OFF - Relay is not energized on uSwitch power up.
2. ON - Relay is energized on uSwitch power up..
3. LAST - Relay is put in the state it was in when on uSwitch power up..
Momentary (sec)
This timer field puts a relay into momentary (pulse) mode. When Momentary is set to zero, the relay is latching. Clicking
on the relay’s control changes its state to the opposite state leaving it in that state (latched) indefinitely. A non-zero value
in the
Momentary
field puts the relay in momentary/pulse mode. In this mode, each time the relay is clicked it changes its
state and retains in the new state for the number of seconds specified in the Momentary field. After the second counter
(on the display for the relay) elapses the relay returns to its original state. (Note, if wiring a uSwitch in parallel with
another physical momentary switch, such as a garage door opener, the relay must be put into momentary/pulse mode. If
not whenever uSwitch relay is closed the pre-existing switch will have its functionality blocked). A single relay cannot be
configured to
Momentary
and any other Mode at the same time.
Ping Auto Reboot
When checked the selected relay will act as an automatic watchdog reboot device and its state will be automatically
controlled as specified in the settings from the
Watchdog Configuration
page. Like momentary mode, watchdog mode,
is mutually exclusive). Manual operation of the relay is disabled in Watchdog mode.
(In Ping Auto Reboot Mode the
Power on State Must be Programmed to “OFF”).
Allows Master Control
(applies to uSwitch and uSwitchPro)
When
Allows Master Control
is checked the selected relay forfeits local control and only a remote uSwitch’s GPIO, or
virtual input can control the relay. When a remote uSwitchPro is programmed to control this relay (on remote uSwitchPro’s
GPIO Configuration page) the state of the relay will synchronize to the GPIO (input) from the remote uSwitchPro. This
enables a remote uSwitch virtual input or remote GPIO to sync multiple devices such as door locks on a campus from a
single action or uSwitch. uSwitchPros can be set up to remotely control a relay on a standard or Pro uSwitch. This mode
is mutually exclusive to other modes that are locally controlled.
Timed Reboot
The “Timed Reboot” field can be programmed to either OFF, 12, 24, 36, or 48 hours. In Timed Reboot mode the relays
will automatically change their state after the specified time period expires and then return to its original state after the
number of seconds specified in the momentary field. A value must be specified in the momentary field because Timed
Reboots are always momentary. (there is also a test option for 30 seconds, since it is unreasonable to wait for 12 hours
to test this feature. Timed reboots are intended to be used as a secondary reset strategy.
Sync to Local GPIO
This pulldown menu ties the respective relay to the respective GPIO. The choices are “OFF, ANY, LOW, HIGH”. If “OFF”
is not selected than the state of the relay will synchronize with the specified state of the GPIO. When ANY is
specified the Relays output changes state with every state change of the GPIO. When LOW is specified the
Relay will always track when the GPIO goes LOW however the relay remains under manual control if the GPIO
state is HIGH. When HIGH is specified the Relay will always track when the GPIO goes HIGH however the relay
remains under manual control if the GPIO state is LOW. The relay will either be in the same state as the GPIO
when it is tracking or the opposite state of the GPIO depending on the “Sync Inverts GPIO” field.
