LED Indicators
Look on the left hand edge of the decoder circuit board (the one that
has the gold wheel spinning). There are LED indicators for several
functions located in a column. From top to bottom they are:
Gd Read
(Green) - will light for approx 1 second when a decal is read
Lsr Act
(Yellow) - should be on when the laser is on
Rst Act
(Green) - will light when the unit is being reset
Data0 Act
(Red)
Data1 Act
(Red)
These LED’s indicate when the Wiegand communication lines (data 0
and data 1) are active. When the BA-220 DualBeam is not
transmitting, the LED’s should be off. If one or both of the LED’s are
on constantly the data line is connected to ground. Remove the wires
connected to Wiegand 1 and Wiegand 0 and see if the LED’s go off.
If they do, the wiring may be at fault. Trace the communication wiring
and be sure it is connected properly to the access control equipment.
Loop In
(Yellow) - will light when the loop input is active
DigLo
(Yellow) - will light when data is flowing from receiver board
DigHi
(Yellow) - will light when data is flowing from receiver board
Diag
(Green) - will light when decoder is in programming mode
Heat
(Red) - will light when heater is turned on
Sync
(Green) - will light when gold wheel is spinning
Reading a test barcode:
Refer to page 28 for how the barcode must be held for the BA-220
DualBeam to read it. Then, pass the barcode through the laser line.
The green indicator on the outside of the box should light up for
approximately 1 second to show that the barcode was read. Also, Gd
Read (green) on the left edge of the decoder circuit board should also
light up for 1 second.
