MaxiScan 3100 - Installation Guide 23
4 Input / output synchronization
Output synchronization
An external device (switch, alarm, indicator light) can be triggered by a good read or
unsuccessful read by the MaxiScan 3100. The external device is connected to pins 7
and 8.
Output trigger
Good read The output device is triggered when the MaxiScan 3100 performs a
good read.
No read The output device is triggered when the MaxiScan 3100 does not perform
a good read. An input synchronization trigger is required (no read = no
read before timeout).
Hardware action
Current on The output device operates when current flows between pins 7 and 8.
The output device stops operating when the current stops flowing. An
output trigger (good read or no read) must be activated.
Current off The output device operates when no current flows between pins 7 and
8. The output device stops operating when the current starts to flow. An
output trigger (good read or no read) must be activated.
Software action
The MaxiScan sends a specified character following a good read or no read. This
software output can be combined with an action (current on or current off).
