Label Registration Mode (U5)
This mode resets all unit parameters to a predefined set of defaults for the purpose of registering up to 5 labels
prior to using the verification mode defined previously. When this “U5” command is activated, an intermittent
(fast) buzzer sounds. Scan the labels you want to register (up to 5) and when done scan the Z7 label. The
predefined defaults are the following:
• Reads all barcodes by symbology.
• No fixed number of digits defined (32 digits max.).
• Mass scan, multiple scan. Trigger disabled. Read timing is coupled with trigger.
• Small and large.
• No verification. No “Bad Read (BR).”
• Buzzer 8 KHz and 2KHz, volume maximum.
• Buzzer after decoding (200 ms).
• RS-232C (9600 bps, 8, 1, np, no handshaking).
Read Rate Mode (U8)
This mode resets all unit parameters to a predefined set of defaults for the purpose of checking the scanner
read rate. When activated, the test result is sent via RS-232C and indicates the ratio of the number of
successful reads to the total number of attempts. The test result is reported in the following format:
700 d OK: 93.5%
*CODE-39 TEST*
Where:
• 700d indicates the number of times the decoder
ran while scanning at 700 scans per second (the
number can be lower the 700 with poor quality
barcodes).
• 93.5% indicates the percentage of good reads to
total attempts.
• The control character to be output is CR (0DE
carriage return line fed), “ESC[3A” (cursor 3 line
UP).
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 disabled.
• Small and large.
• Buzzer 3 KHz, volume max.
• Buzzer after decoding (10 ms.)
• Good LED after decoding (green 100 ms)
• RS-232C (9600 bps, 8, 1, np, no handshaking).
