Input / output synchronization
Input synchronization
Voltage level
(high)
The M1000 is triggered when the voltage level is high on pin 12. It
remains active until the voltage is removed or until a good read
(according to setup).
Voltage level
(low)
The M1000 is triggered when the voltage level is low on pin 12. It
remains active until a voltage is applied or until a good read
(according to setup).
Rising edge
The M1000 is triggered by a rising edge voltage on pin 12. It remains
active until a good read or timeout (according to setup).
Falling edge
The M1000 is triggered by a falling edge voltage on pin 12. It remains
active until a good read or timeout (according to setup).
Rising &
falling edge
The M1000 is triggered by a rising or falling edge voltage on pin 12. It
remains active until a good read or timeout (according to setup).
Software
The M1000 is triggered when a start character is received. It remains
active until it receives a stop character or timeout (according to
setup). The start and stop characters are user programmable. This
software trigger can be combined with any of the above. See
EasySet for more details.
Output synchronization
A good read or bad read by the M1000 triggers an action on pin 14 of the M1000.
Trigger
Good read
The output device is triggered when the M1000 performs a
good read.
Bad read
The output device is triggered when the M1000 does not
perform a good read during an input synchronization cycle.
Action
Voltage
level (high)
The output trigger event (good read or bad read)
disconnects pin 14 from the ground. A high level voltage
applied to pin 14 by the output device remains at a high
level until time out.
Voltage
level (low)
The output trigger event (good read or bad read) grounds
pin 14. A high level voltage applied to pin 14 by the output
device drops to a low level until time out.
Software
The M1000 sends a specified character when it performs a good read or
does not perform a good read during an input synchronization cycle
(according to setup). This software output can be combined with an action
voltage level (high) or voltage level (low).
