General Customer Guidelines for

Peripheral Selection

Scanners, printers and other peripherals can be an appropriate complement to voice-centric

tasks. Vocollect offers a variety of off-the-shelf solutions that have been verified to work with

the T5 Series and T2 Series systems for scanning and many flexible options for printer

interfacing.

Vocollect strongly recommends that users always thoroughly evaluate scanner options or

printers in the actual work environment before purchasing devices.

When selecting scanners for use with the wearable computers, users should consider:

- How well the device will stand up to the physical demands of the workplace.

- If the device is ergonomically compatible with the working environment.

- How well the device functions in environmental extremes that could be

encountered in the workplace.

- Choosing wired scanners that communicate via RS-232 and character-based

protocols, which are the most widely used.

- Whether the scanner can be configured to meet the specific transmission

requirements of the T5 Series and T2 Series devices (baud rate, parity, etc.).

- Compatibility with any other scanners that may be used at the site. For

example, if two different types of scanners will be used at the same site, they

can easily be interchanged without reconfiguring the T5 Series and T2 Series

devices if both have the same RS-232 characteristics.

- Verifying that the scanner can decode the barcode symbols used at the site.

- Choosing Bluetooth peripherals that are Class 2, support the serial port

protocol, and are easily programmed for the application.

- Choosing Bluetooth peripherals that do not require security when working

with the T2 Series may decrease implementation complexity and

management.

When selecting printers and printing options:

- It is likely that a WLAN capable printer will provide the most flexible printing

options.

- Verify that the warehouse management software or Vocollect VoiceLink will be set

up to drive any host-based printing from the T5 Series and T2 Series devices.

- If commands are being sent to printers from the task using an ODR (Output Data

Record), it will be necessary to provide a table of printers and associated network

addresses or names in the task.
