Worth Data 701 RF manual Characters, Where b is the Bar Code ID character see the Code 128 setup

•You can use the Postamble to trim characters from the data you are entering into the RF Terminal. You can trim from 1-15 characters from the data by creating a Postamble of:

~x

where ~ is ASCII 126 and x is a single hex digit 1-F (corresponding to 1-15). Data that is shorter than the trim amount is transmitted without trimming. Postambles trim characters from the end of the data. Here are some examples:

Data		Postamble	Data Transmitted
123		XYZ	123XYZ
12345678		~3XYZ	12345XYZ
12345678	~9		12345678
12345678901		~A	1
123456	~5		1
	Postamble trims trailing characters

•Using the Bar Code ID feature and the Postamble, you can trim data selectively, trimming characters only on the bar code type specified. To use selective trimming, enter:

~bx

where b is the Bar Code ID character (see the Code 128 setup

parameter) and x is the number of characters to trim from the end of the data. For example, ~b2~c1 says “trim 2 characters from Code 39 data and 1 character from UPC-A data”. Remember that the Postamble

trims trailing data.

•Lastly, the Postamble can be used to check a maximum character length for data entered. To check for length in the Postamble, enter:

nnmm

where is ASCII 124, nn is the two-digit minimum and mm is the two- digit maximum. 0210 would check for a minimum of 2 characters and a maximum of 10 If you try to scan a bar code outside the minimum or maximum lengths, no decode will result. Entering data by keypad is not affected.

Characters

This setting allows the RF Terminal to output chosen ASCII characters in place of the actual characters entered. For example, if you scanned the

number 1 (hex 31) and wanted the RF Terminal to output hex 92 instead, you would enter 3192 for the Characters parameter. This would re-assign

the output characters, with the RF Terminal outputting hex 92 every time it sees hex 31. To re-assign characters:
