Note: Input channels are active when the input is switched-to-ground (same potential
as P1:12). For the input to be considered active, the voltage at the input channel must
be less than 1V relative to P1:12 for at least 100msec. For the input to be considered
inactive, the voltage at the input channel must be greater than 3V for the same
minimum amount of time. All input channels are equipped with internal pull-up
resistors. Therefore, when an input is disconnected from an input channel, the input is
considered inactive.
5.2 BU-2H06D-7588 Safety Link
SAFETY LINK ENABLED – In the event that the handheld and base unit lose communication,
the base unit will deactivate any active outputs. In the event that communication is re-
established, no active commands can be present in the initial communication in order for a link
to be established and for outputs to be affected by the handheld and by proxy in this application
the other base units. Safety Link is based on a five (5) second window – in the event that no
message is received from the handheld within five (5) seconds after receipt of the last valid
message, any active outputs will be disabled.
