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

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. To

set a Postamble:

1 Select option “8” from the RF Terminal Setup menu then “2” for Postamble from the Other

Settings menu.

2 Enter the desired characters (up to 15). Pressing the shift key will turn the cursor red to indicate

that the shift is active. Pressing shift again will turn the cursor white and return to unshifted

mode..

3 Press “ENTER”.when you are finished entering data.

• To clear the Postamble and return to the default (no Postamble defined), press “CLEAR”.

• 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:

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

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 135 136
