3.10 Synchronization
It is possible to synchronize D-POS units in order to avoid that they
interfere with each other. This is done by connecting GND (screw
terminal 7) and SYNC (screw terminal 8) on one unit to the
corresponding screw terminals on the other unit.
It is possible to synchronize the unit with an old D-POS unit and up
to three units can be connected for synchronization.

3.11 Walk test mode
To verify the size of the RFID field a walk test mode can be activated
with DIP8.
When a portable trigger (e.g. SMILE ID or D-ATOM) is inside the RFID
field, its LED will flash once per second. The color of the LED
indicates if it is configured to send an alarm when passing an RFID
field with the ID code and zone number transmitted by D-POS II:
red for sending an alarm, green for not.
During walk test mode the portable trigger will not make any transmission
to NOVO or TREX2G etc., so do not forget to return DIP8 to OFF position when
RFID field check is done.
