JMP Protocol
Latching may be enabled for any of the digital inputs. This is a form of event
capture which can be very useful in monitoring pulsed signals. A
latching
input may be set to trigger on either a positive going or negative going
signal edge. In waiting for the event the input is considered to be armed.
When the trigger signal is detected the input changes state.

Latching Inputs
Once latched a timer can be configured to reset the
latch after a period
suitable for the application. Alternatively the
latch might hold the
condition indefinitely until it is manually reset or acknowledged by the
application programming. This may be appropriate in a fire alarm situation.

Debouncing Inputs
Relays and switches have mechanical contacts which physically make or break
a circuit. Rarely will the contacts come together solidly or separate
decisively without bouncing (briefly making and breaking the circuit). This
can raise havoc with digital
latching and counting circuits that might be
monitoring through the relay/switch contact. It can result in
latching at the
wrong time (when the relay opens for instance) or in extra counts. Both are
undesirable.

Digital Inputs may be latched. Depending on configuration these may
reuire manual intervention to be reset or unlatched. The command 'r2'
resets any active
latching on Digital Input 2.
