transmission, the host sends the XON character (DC1, hex 11). Data transmis- sion continues where it left off when XOFF was sent. Default = RTS/CTS, XON/ XOFF and ACK/NAK Off.

RTS/CTS On

* RTS/CTS Off

XON/XOFF On

* XON/OFF Off

ACK/NAK On

* ACK/NAK Off

Host ACK Selection

Some applications require that the host terminal (or server) approve or reject incoming barcode data and notify the operator of these actions. These applica- tions require that the host maintain control over the response indicators emitted from the source image scanner. Turning the Host ACK selection on, configures the cordless system image scanners to respond to commands from the host system.

The following criteria must be met for the Host ACK to work correctly:

The cordless system must be configured for Host Port RS-232 (terminal ID =

000)or USB COM Emulation (terminal ID = 130).

RTS/CTS is defaulted off. You must enable it if the host system requires it.

Host ACK must be enabled (page 2-12).

System performance degrades when using Host ACK at rates lower than 9600.

The host terminal software must be capable of interpreting the barcode data, make decisions based on the data content, and send out appropriate escape commands to the source image scanner.

Escape commands are addressed to the source image scanner via “Application Work Groups.” Once a command is sent, all image scanners in a group respond to that command. Because of this situation, it is recommended that each image scanner is assigned to its own group in host ACK mode.

The commands to which the image scanner responds are listed on page 2-13. The <ESC> is a 1B in hex. A typical command string is y <ESC> x, where “y” is the application work group number, “<ESC> x” is the escape command, and the comma is the terminator, which is required.
