3-4 MS-3 Laser Scanner User’s Manual

3–Protocol

Protocol

Point-to-Point (standard)

Definition: Protocols define the sequence and format in which information is trans-

ferred between the scanner and the host, or in the case of Multidrop,

between scanners and a concentrator.

Usage: In general, the point-to-point protocols will work well in most applica-

tions. They require no address and must use RS232 or RS422 commu-

nications standards.

Default: Point-to-Point

Options: 0 = Point-to-Point

1 = Point-to-Point with RTS/CTS

2 = Point-to-Point with XON/XOFF

3 = Point-to-Point with RTS/CTS & XON/XOFF

4 = Polling Mode D

5 = Multidrop

6 = User Defined

7 = User Defined Multidrop

If selecting one of the options from 0 to 4 (Point-to-Point, Point-to-

Point with RTS/CTS, Point-to-Point with XON/XOFF, Point-to-

Point with RTS/CTS and XON/XOFF, or Polling Mode D), use the

<K1140,protocol> format.

Option 5 through 7 are special cases and discussed later in this section.

Definition: Standard Point-to-Point requires no address and sends data to the

host whenever it is available, without any request or handshake from

the host.

Usage: Used only with RS232 or RS422.

Serial Cmd: <K140,0>
