Accumulate Mode must be turned on using the bar coded Setup Menu or by using the keypad. Accumulate Mode is located in the

Code 39 parameters. Choose 4 to Enable or 5 to Disable this feature.

This numeric Code 39 "Barpad" illustrates ACCUMULATE Mode. Scan 5, 3, 8, and Enter. The RF Terminal transmits a single

message of “538”.

Code 93 Specifications

Code 93 is variable length, continuous, bi-directional, compact code. Code 93 is an alphanumeric bar code which consists of 43

data characters (0-9,A-Z,$/+%.- and Space), 4 control characters, and a unique start/stop character. The entire set of 128

ASCII characters is represented in Code 93 using combinations of control characters and data characters.

The control characters are , , , and . Pairing these control characters with normal data characters creates full ASCII

93. It is almost identical to the pairings for Code 39; Code 39 uses $M to produce a Carriage Return (ASCII 13) character -- Code

93 uses M to produce the Carriage Return.

Code 93's two built-in check digits greatly minimize the possibility of reader substitution errors. The bar code reader never trans-

mits digits the check digits. Code 93's Start and Stop characters are also never transmitted.

If you have not decided which bar code type to use for your application and are considering using Code 93, while we agree that

Code 93 is an excellent code, we believe that Code 128 is generally preferable because:

 Code 93 does not have the numeric compression capability that 128 does, and

 Code 93 requires pairings to make all Full ASCII characters while 128 does not.

Codabar Specifications

Codabar is widely used in libraries, blood banks, the cotton industry and transportation industries. Its character

set consists of numbers 0 through 9, and punctuation characters + . - / : and $. Symbols a, b, c, d, t, n, * and e

are used as start and stop characters. Characters are constructed of four bars and three spaces.

Codabar is a numeric-only code, but different combinations of start and stop characters can be used to identify

different types of labels. Codabar's variable data length and extremely low error rate make for a versatile bar

code.
