The Handheld barcode scannner device usually uses a cable in order to connect the barcoder as well as the number laptop or computer products for info connection. In line with the various connection protocols, it might generally be separated into USB, serial dock, key-board dock and other kinds of interface varieties.

1. USB interface

The USB interface is regarded as the traditionally used interface for barcode scanning devices, and will usually be applied to well known systems available on the market, which include Microsoft windows techniques, Macintosh Operating system, Linux, Unix, Android mobile phone, and so forth. Using this USB interface usually can keep the pursuing three various protocols of connection:

USB-KBW:

That is, the USB key-board dock, like the method of utilizing a USB key-board, is regarded as the frequently used connection strategy. It can be connect and play, fails to should set up motorists, and fails to assist demand set off control. Usually use text, WORD along with other text result instruments to test.

USB-COM:

That is, the USB online serial dock (Virtual Serial Harbour). When utilizing this connection interface, it will always be necessary to use a online serial dock driver. Despite the fact that a physical USB interface can be used, it simulates serial connection and will assist demand set off control.

USB-HID:

Also known as HID-POS, it is actually a high-pace USB transmission protocol that fails to demand driver installing. When utilizing it, it will always be necessary to create matching getting software program for info interaction, which can assist instruction-triggered control.

Serial interface, also referred to as serial connection or serial connection interface (usually termed as COM interface), is usually traditionally used in manufacturing job areas. It has the features of very long transmission length, secure and reliable connection, and fails to rely on complex techniques. It has numerous interface approaches. Diverse, for example Dupont cable, 1.25 terminal cable, 2. terminal cable, 2.54 terminal cable, and so forth.

At the moment, the TTL levels transmission and RS232 transmission result are often applied to the scanning device. The actual interface is generally a 9-pin serial dock (DB9). When using the serial dock, you need to concentrate on the connection protocol (dock variety, parity tad, info tad, end tad, and so forth.).

RS232 interface:

RS232 interface, also referred to as COM dock, is actually a normal serial dock, which can usually be directly attached to laptop or computer products. The serial dock instrument is required for regular result, for example serial dock debugging helper, very terminal along with other instruments. No driver installing is required. Demand causing is reinforced.

3. Key-board dock interface

The key-board dock interface is likewise named PS/2 interface, KBW (Key-board Wedge) interface, which is actually a 6-pin round interface. It absolutely was an interface strategy employed by earlier keyboards. 1 connector is attached to the barcode viewer, one is attached to the laptop or computer key-board as well as the other is attached to the number laptop or computer of the laptop or computer. Written text result is usually applied to a pc, connect and play.
