Worth Data 7000 manual Bar Code Options, Automatic Check Back, Code 3 of 9 Code

•Several special keys on the RF Terminal keypad can generate a response automatically, sending a separate message to the host by simply pressing the appropriate control key (without pressing the ENTER key afterward). This allows for simple and fast scrolling by the operator. The arrow keys, Begin, End, and Search are the specific keys supported. The default setting is to require the ENTER key to be pressed before data transmission.

•If you set this feature to ON, in order for the RF Terminal to transmit the following values, the corresponding Control Key must be the first key pressed in a data entry sequence. If it is not the first data entered, the arrow key is ignored.

Control Key on RF Terminal	Code transmitted to Host
Up Arrow	FS (ASCII 28)
Down Arrow	GS (ASCII 29)
Left Arrow	RS (ASCII 30)
Right Arrow	US (ASCII 31)
Begin	ETB (ASCII 23)
End	CAN (ASCII 24)
Search	VT (ASCII 11)

The message is sent to the host as:

Bytes	Function	Value
1	RF Terminal ID	0-9, A-Z, a-z, - =
2	Data Transmitted	ASCII Value from Table Above
Last	Terminator of Message	CR

Automatic Check Back

This parameter should not be changed under normal circumstances. After the host sends a prompt, the Terminal goes to sleep waiting on the operator to key or scan input in response to the prompt. It waits until the Automatic Shut Off time or until the operator responds. This parameter sets the time that the Terminal stops waiting on input from the operator, discards the current prompt, and goes back to the host to see if there is a change in instructions. If no change, the host must resend the prompt again because the Terminal has discarded the original prompt. The host now has the opportunity to change a prompt. The time can be set in increments of 5 seconds, up to 495 seconds. The default value is 00. The values possible for entry are 00-

99.An entered 99 gives 99x5 seconds, or 495 seconds between check backs. The Terminal sends back an ASCII 07 for the data back to the host (ID ASCII 07 CR). To change this value press the 6 key in the RF Configuration menu and enter the 2 digit value desired.

•The Start and Stop character for Code 39 is the * character. Setting 4 determines whether or not those characters are transmitted to the computer along with the data. For example, at setting ON, the data of 1234 would be transmitted as *1234*. Transmitting the start and stop characters can be useful if you need to differentiate between data that comes from a bar code versus data coming from the keypad.
