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 receiving device for the next

character in the serial data stream. The number of stop bits (one or two)

selected depends on the number the receiving terminal is programmed to

accommodate. Set the number of stop bits to match host device requirements.

When enabled, this parameter transmits data in an 8-bit ASCII format. This

allows the scanner to interface with devices requiring that protocol. The

default is 7-bit ASCII.

Select the intercharacter delay option matching 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.

A code ID character identifies the code type of a scanned bar code. This may

be 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. Code ID characters

are: A = UPC - A, UPC - E, EAN - 13, or EAN - 8; B = Code 39; C = Codabar;

D = Code 128; E = Code 93; F = Interleaved 2 of 5; G = Discrete 2 of 5;

K = EAN 128; J = MSI Plessey.

Enabling this parameter, with the Transmit Code ID Character parameter

enabled allows you to send the AIM code identifier in lieu of the Symbol

identifiers listed above. The identifier will be sent as a three character prefix, in

accordance with AIM specifications for symbology identifiers. See AIM's

Guidelines on Symbology Identifiers for full details.
