ZBA Z-3060 User Manual - 4. Connecting

4. Connecting 

4-1. Power 

The scanner requires a minimum of 250mA at 5 VDC power.    The interface cable 

that comes with the scanner supports both direct power (where the scanner takes 

power from the host machine) and external power (that’s what the supplied power 

adapter is for).  A sufficiently robust POS system can support a scanner 

successfully without external power; a POS system with a barely adequate power 

supply may produce erratic performance (either of the POS system itself, or of the 

scanner, or both) when a scanner is attached.  Unless you are sure your POS 

system can candle such loading, it is recommended that you use the supplied 

power adapter.  When an external adapter is connected, the scanner does not 

take power from the host. 

The scanner turns on when power is supplied, and turns off when power is 

removed.    There is no on/off switch on the scanner itself. 

Use only an AC/DC power adapter approved for the scanner.  Use of other 

power supplies may cause damage to the scanner, and void the factory warranty. 

4-2. Verifying Scanner Operation 

Please follow the procedure below to verify scanning operation. 

1.  Insert the 10-pin modular plug of the Interface cable into the scanner 

until a firm click is heard. 

2.  Plug the power adapter into the jack on Interface cable if necessary. 

3.  Plug the AC end of the power adapter into an AC outlet, or plug the 

other end of cable into host if power adapter is not needed.    The 

scanner powers up, the buzzer sounds four beeps and the LED 

indicator glows. 

4.  Present a known-good test barcode to the scanner.    The scanner 

should issue a short beep and the LED should flash red momentarily.   

[if the scanner is connected to a keyboard wedge for this test, it 

should read one barcode, beep, then remain with a red LED 

indicating light.  This is normal when the keyboard wedge is not 

connected to a live host terminal.] 

Note: if the scanner does not produce any beeps, or produces the wrong 

beeps, or the LED does not light up, remove the power connection and 

refer to the section on Troubleshooting.
