User Defined Address
Definition: User Defined is considered to be in a polled mode only if an address
has been assigned.
Serial Cmd: <K140, 6,RES,address,REQ,EOT,STX,ETX,ACK,NAK,from host>
Default: No address
Options: Any ASCII character except a null.
User Defined Example
Definition: Example: ACK/NAK protocol can be configured using User Defined.
The scanner will transmit data to the host when an ACK is received. If a
NAK or response timeout occurs, the scanner will re-send the data to
the host up to 3 more times before aborting.
Tip: To use User Defined Point-to-Point, first select Point-to-Point
<K100,0> and then User Defined <K100,6>.
Example: To select an unpolled ACK/NAK User Defined protocol with
LRC disabled, send <K100,0><K100,6,,,,,,,^F,^U><Kc0>. ACK and
NAK will be displayed in the menu.
Serial Cmd: <K140,6,RES,address,REQ,EOT,STX,ETX,ACK,NAK,from host>
Default: No assignment
Options: Any ASCII character except a null. Control characters can be used to
define RES through NAK in serial commands.
From Host
Definition: This option allows the handshaking protocol to be initiated from the
host, if not configured in an unpolled mode. Messages sent to the host
will include the scanner's defined protocol. The status of From Host
determines if messages sent from the host to the scanner must include
the defined protocol. If From Host is disabled, the defined protocol is
not included. If From Host is enabled, the defined protocol must be
included.
Serial Cmd: <K140,6,RES,address,REQ,EOT,STX,ETX,ACK,NAK,from
Default: Disabled
Options: 0 = Disabled
