USB Interface
Introduction
This chapter provides instructions for programming the scanner to interface with a USB host. The scanner connects directly to a USB host, or a powered USB hub. The USB host can power the scanner.
Throughout the programming barcode menus, default values are indicated with asterisks (

Connecting a USB Interface
The scanner connects to USB-capable hosts, including:
•
TGCS (IBM) terminals
•
Apple ™ desktop and notebooks
•
Other network computers that support more than one keyboard.
The following operating systems support the scanner through USB:
•
Windows 8, 10
•
MacOS 8.5 - MacOS 10.6 (Supported via HID Keyboard only)
•
IBM 4690 OS
•
Linux
The scanner interfaces with USB hosts that support Human Interface Devices (HID).

USB Connection
USB Interface
To connect the cradle to a USB host:
1.
Attach the modular connector of the USB interface cable to the cable interface port on the digital
scanner. See Connecting Cradle Cable on page 32 .
2.
3.
4.
Plug the series A connector in the USB host or hub, or plug the Plus Power connector in an available port of the IBM SurePOS terminal.
Ensure all connections are secure.
Pair the digital scanner to the cradle by scanning the barcode on the cradle.
5.
6.
7.
8.
Select the USB device type by scanning the appropriate barcode from USB Device Type on page 194 .
On first installation when using Windows, the software displays a prompt to select or install the
Human
Interface Device
driver. To install the Human Interface Device driver provided by Windows, click
Next
through all the choices and click
Finished
on the last choice. The digital scanner powers up during this installation.
To modify any other parameter options, scan the appropriate barcodes in this chapter.
Connect an external power supply if desired.
NOTE:
Interface cables vary depending on configuration. The connectors illustrated in Figure 22
are examples only. The connectors may be different from those illustrated, but the steps to connect the cradle remain the same.
Disconnect the host cables before the power supply, or the digital scanner may not recognize the new host.
If problems occur, see
Troubleshooting on page 52

USB Parameter Defaults
Table 16
lists the defaults for USB host parameters. If any option needs to be changed, scan the appropriate barcode(s) provided in the Parameter Descriptions section beginning on
194 .
NOTE:
See Standard Parameter Defaults for all user preferences, hosts, symbologies, and miscellaneous
default parameters.
See
Country Codes on page 377
for USB Country Keyboard Types (Country Codes).

USB Device Type
Select the desired USB device type.
NOTE:
When changing USB device types, the scanner automatically restarts. The imager issues a power-up beep sequence.
1.
Before scanning USB CDC Host (Note 1) on page 195
, install the appropriate USB CDC Driver on the host to ensure the scanner does not stall during power up (due to a failure to enumerate USB). Go to www.zebra.com/support , Support & Downloads > Barcode Scanners > USB CDC Driver, select the appropriate Windows platform, and download the appropriate CDC Driver (64 bit or 32 bit).
2.
3.
To recover a stalled scanner:
Install the USB CDC Driver or
Unplug the USB cable and add power. Connect the scanner via Bluetooth and scan HID Keyboard or another host.
Select
IBM Hand-Held USB
to disable data transmission when an IBM register issues a Scan Disable command. Aim, illumination, and decoding is still permitted. Select
OPOS (IBM Hand-held with Full
Disable)
to completely shut off the scanner when an IBM register issues a Scan Disable command, including aim, illumination, decoding, and data transmission.
Select
USB HID POS
to communicate over a USB cable with Universal Windows Platform (UWP) applications running on Windows 10 devices.

USB CAPS Lock Override
This option applies only to the HID Keyboard Emulation device. When enabled, the case of the data is preserved regardless of the state of the caps lock key. This setting is always enabled for the “Japanese,
Windows (ASCII)” keyboard type and can not be disabled.

USB Ignore Unknown Characters
This option applies only to the HID Keyboard Emulation device and IBM device. Unknown characters are characters the host does not recognize. When
Send Barcodes With Unknown Characters
is selected, all barcode data is sent except for unknown characters, and no error beeps sound. When
Do Not Send
Barcodes With Unknown Characters
is selected, barcode data is sent up to the first unknown character, then the imaging imager scanner issues an error beep.

USB Polling Interval
Scan a barcode below to set the polling interval. The polling interval determines the rate at which data can be sent between the scanner and host computer. A lower number indicates a faster data rate
NOTE:
When changing USB Device Types, the imaging imager automatically restarts and issues a disconnect-reconnect beep sequence.
IMPORTANT:
Ensure your host machine can handle the selected data rate.

Function Key Mapping
ASCII values under 32 are normally sent as a control-key sequences (see Table 30 on page 457
). When this parameter is enabled, the keys in bold are sent in place of the standard key mapping. Table entries that do not have a bold entry remain the same whether or not this parameter is enabled.

If you configure the imaging imager scanner and find the settings were not saved, or changed, when the system is restarted scan the barcodes that follow to override USB interface defaults.
Scan a barcode below after setting defaults and before configuring the imaging imager scanner.
TGCS (IBM) USB Direct I/O Beep
Parameter # 1360 (SSI # 550h)
The host can send a direct I/O beep request to the scanner. If you select
Ignore Direct I/O Beep
, the scanner does not sound beeps on this command. All directives are still acknowledged to the USB host as if they were processed.
