RS-232C Options (Continued)
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.
ASCII Format
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.
• Intercharacter Delay
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.
• Transmit Code ID 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.
• Transmit AIM ID Character
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.
