Scanner Test Mode (U0)
This mode resets all unit parameters to a predefined set of defaults for the purpose of putting the scanner into
a test mode which reads barcodes continuously. The predefined defaults are the following:
• Reads all barcodes by symbology
• No fixed number of digits defined (32 digits minimum).
• Normal scan, continuous scan.
• Large only.
• No verification, no “Bad Read (BR).”
• Buzzer 3KHz, volume maximum.
• Buzzer after decoding (10 ms).
• Good LED after decoding (green, 100 ms).
• RS-232C (9600 baud, 8, 1, no parity, no handshaking).
Straight Across Scan Mode (U3)
This mode resets all unit parameters to predefined defaults for the purpose of allowing straight across scanning
of up to 4 labels. The predefined defaults are the following:
• Reads all barcodes by symbology.
• No fixed number of digits defined (32 digits max.)
• Normal scan, multiple scan.
• Trigger disable.
• Small and large.
• No verification, no “Bad Read (BR).”
• Buzzer 3KHz and 2KHz, volume max.
• Buzzer after decoding (200 ms).
• Good LED after decoding (green, 200 ms).
• RS-232C (9600 baud, 8, 1, no parity, np, no handshaking).
Label Verification Mode (U4)
This mode resets all unit parameters to a predefined set of defaults for the purpose of verifying barcodes
against a set of pre-registered labels (up to 5 labels).With the trigger set to use the red LED lights when there
is a bad read and stays on for 200 ms. The unit determines good or bad read based upon the registration of
labels input during the use of the “U5” command mode defined below. It reads only the registered labels as
normal. When it encounters an unregistered label, the red LED lights and sounds a “bad” buzzer. The pre-
defined defaults are the following:
• Reads all barcodes by symbology.
• No fixed number of digits defined (32 digits max.).
• Normal scan, multiple scan.
• Trigger enabled. Read timing is coupled with trigger.
• Small and large.
• No verification, no “Bad Read.”
• Buzzer and 3KHz and 2 KHz, volume max.
• Buzzer after decoding (200 ms).
• Good LED after decoding (green, 200 ms).
• RS-232C (9600 bps, 8, 1, np, no handshaking).
