•Using the Bar Code ID feature and the Preamble, 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 front 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 Preamble trims leading

data. This applies to One-Way and host prompted communication.

•Lastly, the Preamble can be used to check a minimum/maximum data

length for bar code data entered. To check for bar code length in the Preamble 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 maxi- mum 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.

Postamble

Other

Postambles are user-defined data that is attached to the end of data (bar code or keyed) that is transmitted to the host by the RF Terminal. For

example, if you set a Postamble of @@ and scanned bar code data of 12345, 12345@@ would be transmitted to the host.

•By default, the RF Terminal has no Postambles configured. Postambles

can contain up to 15 characters scanned from the bar coded FULL ASCII Menu. To set a Postamble:

1.Scan the Postamble bar code or select Postamble from the keypad menu.

2.Scan the desired characters (up to 15) from the FULL ASCII Menu.

3.Scan the SET bar code, or if using the keypad, press ENTER.

4.To clear the Postamble and return to the default (no Postambles defined), scan CLEAR at step #2, and then continue with your setup.
