80
Divide the sum by
43
: (thus the name modulus 43)
108/43 = 2 with a Remainder of 22
Find the character corresponding with the remainder.
M (
value 22) is the CHECK CHARACTER
The data becomes
123XYZM
, with
M
added as the Mod-43 check character.

Accumulate Mode
Accumulate Mode
is an option allowing the RF Terminal to accumulate multiple bar codes in its buffer, then transmit them to the
computer as if they had been a single bar code. This is useful for entering quantities and other variable data.
Accumulate Mode
works with Code 39, Code 93 and Code 128 only and can't be used with a check digit. When the RF Terminal
reads a bar code with a
space as the first character
, it beeps and buffers the data without transmission. It continues to read and
buffer bar codes (up to 40 characters) until it reads a bar code
without a leading space
. Once it reads this last bar code, the entire
buffer (including that last code) is transmitted as one long bar code. A “double-minus” sign (--) bar code clears the buffer. The
ENTER
code on this Barpad is a Code 39
Start/Stop Character
only.
