Intercharacter Delay; Code Id Character; Stop Bit Select - Symbol LS 1220 Product Reference Manual

Stop Bit Select

The stop bit(s) at the end of each transmitted character marks the end of transmission of
one character and prepares the host device for the next character in the serial data stream.
The number of stop bits selected (one or two) depends on the number the host is
programmed to accommodate. Set the number of stop bits to match host device
requirements.
ASCII Format
The number of data bits transmitted may be 7 or 8. This parameter is set to match the host
device's requirements. The default is 7-bit ASCII.

Intercharacter Delay

Select the intercharacter delay option to match the host device requirements. The
intercharacter delay gives the host system time to service its receiver and perform other
tasks between characters. Select from no delay to a 99 msec delay between the
transmission of each character.

Code ID Character

A code ID character identifies the code type of a scanned bar code. This is useful when the
scanner is decoding more than one code type. If a prefix is selected, the code ID character
is sent after the prefix. There are three options:
• Symbol ID - The identifier is sent as a one character prefix. Symbol Code ID
characters are: A = UPC-A, UPC-E, EAN-13, or EAN-8; B - Code 39;
C = Codabar; D = Code 128; F = Interleaved 2 of 5; G = Discrete 2 of 5.
• Aim ID - The identifier is sent as a three character prefix, in accordance with AIM
specifications for symbology identifiers. See AIM's Guidelines on Symbology
Identifiers for full details.
• None - No Code ID character is sent.
