 For safety, the connectors break away if a force strong enough to pull the wearer off-

balance is exerted.

 The connectors are keyed, so that only the correct TCO cable (i.e. headset, barcode or

printer) may be inserted in any given TCO connection point.

 The connector is extremely rugged.

These features make the connectors suitable for the extremes of a production environment.

They also decrease the need for service of the unit because of connector issues or failures.

Scanner Connections for Wired Scanners

Scanners typically require two connections, one for data and one for

power. The data connection is typically a DB9. The only pins used

by the system are pins 2 (receive), 3 (transmit) and 5 (signal

ground). Power connections can be unique, and voltage ranges can

vary.

Most scanners powered by 5V DC include a modular cable that can

be refitted to work with the system.

Vocollect offers a cable (BC-604-203) with the TCO on one end and two connections on the

other. One is a standard DB9 and the other offers an unterminated 5V DC connection. This

may easily be re-terminated and connected to a scanner.

Vocollect offers cables with the TCO and RJ-11 connectors as well as those without any RJ-

11 connectors. For those without RJ-11 connectors, customers can attach any RJ-11

connector they have wired to match their own scanner’s specific pin assignments. These

cables are discussed in the Other Cable Options section.

Wired Interface Protocol

The T5 Series and T2 Series terminals support an RS-232 interface. “RS” is an abbreviation

for “Recommended Standard” of the Electronic Industries Alliance (EIA). This standard

provides a way for character-oriented devices to exchange data. It determines some of the

basic electrical characteristics of the interface.

There are several parameters that are important to understand when configuring RS-232

devices. One important parameter is flow control, which is how devices tell each other to

start or stop transmitting data. The RS-232 device itself does not use flow control for barcode

reading because of the very small amount of data actually transmitted.

Other parameters important to transmission are configured in the device profile in

VoiceConsole (advanced settings of the task package, or task VCF file if using older Talkman

Management Software - TMS). These parameters are summarized at the end of this

document.

By default, many devices will transmit and receive data using ASCII encoding with 8 bits for

data, 9600 bps (bits per second), no parity bit, and one stop bit, terminating their input with

a carriage return/line feed.

Vocollect terminal configuration is extremely flexible. However, it is important to remember

that the RS-232 device parameters also can be modified for compatibility with the Vocollect

system. Most scanners come with configuration sheets or reference material that allow the
