How to Set Up the BA-440 DualBeam
Activating the Aux Input
In addition to connecting the arming trigger to the Aux In- & Aux In+
terminals the Vehicle Detect Mode parameter must be changed from
Scan
to
Loop
by typing
vdm loop
and press
Enter
. Some new
parameters will now appear in the configuration:
Laser Diode Saver Off
- controls when the laser is on. When set to
OFF, the laser will be on constantly. If set to ON, the laser will only
turn on when the Aux In input is active. To change the setting type
lds
on
or
lds off
and press
Enter
.
Loop Delay Time 100 ms
- this is a programmable delay that extends
the Aux In signal “on” time after the vehicle has cleared the loop. It is
useful when the arming loop is located ahead of the reader.
No Read Pulse 1000 ms
- since the Aux In input lets the reader know
when a vehicle is present, the BA-440 DualBeam can now detect
whether or not a barcode was read. When a vehicle passes that does
not have a barcode the reader will close the Aux Out relay for 1000
ms (1 second), which can be connected to an alarm or indicator.
Wiegand No Read On
- if a vehicle passes by without a barcode the
reader can send a special message out the Wiegand port to alert the
security panel or telephone entry system that no read has occurred.
This message is all zero’s and will be sent only if this parameter is set
ON. To change this setting, type
wnr on
or
wnr off
and press
Enter
.
