Communication Between the Cordless System and the HostThe cordless scanner provides immediate feedback in the form of a “good read”indication (a green LED on the scanner and an audible beep) after a bar code isscanned correctly and the base has acknowledged receiving the data. This ispossible since the cordless system provides two-way communication betweenthe scanner and the base.When data is scanned, the data is sent to the host system via the base unit.Confirmation from the host system or the base indicates that the data sent wasreceived by the host. The cordless scanner recognizes data acknowledgement(ACK) from the base unit. If it cannot be determined that the data has beenproperly sent to the base, the scanner issues an error indication. You must thencheck to see if the scanned data was received by the host system.1) Good Read3) Base sendsdata to host2) ACK from baseConnecting the Base When Powered by Host(Keyboard Wedge)A base can be connected between the keyboard and PC as a “keyboard wedge,”plugged into the serial port, or connected to a portable data terminal in wandemulation or non decoded output mode. The following is an example of akeyboard wedge connection:1. Turn off power to the terminal/computer.1 - 18 2020/<strong>3820</strong> User’s Guide
2. Disconnect the keyboard cablefrom the back of the terminal/computer.Disconnect3. Connect theappropriateinterface cableto the base andto the terminal/computer andkeyboard.4. Turn theterminal/computer powerback on.1325. Program thebase for thekeyboard wedge interface. See "Keyboard Wedge Connection" on page 1-21.)6. Verify the base operation by scanning a bar code from the Sample Symbolsin the back of this manual.Note: Without using the 9-volt external, power supply, the base only usesenough power from the host to operate the interface. The scanner’sbattery is not charged when in this mode. Using the 9-volt, external powersupply allows the scanner’s battery to be charged, and no power is drawnfrom the host.2020/<strong>3820</strong> User’s Guide 1 - 19
