Preamble (enable/disable)
Default:
Disabled
Options:
Disabled, Enabled (within any protocol)
Allows you to enable or disable the preamble character(s).
Postamble
Default:
^M^J
Options: Any ASCII character, including control characters.
Allows you to define a one or two character data string that can be added after the
decoded message. For example, defining the Postamble as a carriage return and line
feed would result in the display of each decoded message on its own line.
Postamble (enable/disable)
Default:
Enabled
Options:
Enabled, Disabled (within any protocol)
Allows you to enable or disable the Postamble character(s).
LRC (Longitudinal Redundancy Check)
Default:
Disabled
Options:
Disabled, Enabled
An error-checking routine that verifies the accuracy of transmissions. It is the exclu-
sive OR of all characters following the SOM (start of message) up to and including the
EOM (end of message). What this means is that the binary representation of all the
characters in a transmissions are cumulatively added in a column and each resulting
odd integer is assigned a 1 and each even integer a 0 (two 1s = 0, two 0s = 0, a 1
and a 0 = 1). This extra LRC character is then appended to the transmission and the
receiver (usually the host) performs the same addition and compares the results.
Response Timeout
Default:
12 ms
Options:
0 to 65,000 ms. A zero (0) setting causes an indefinite wait.
Allows you to set the time the scanner will wait before timing out if ACK, NAK, and
ETX are enabled, and a host response is expected.
Intercharacter Delay
Default:
0
. Corresponds to 0 ms displayed in the menu.
Options:
0 to 255. Zero (0) causes no delay between characters.
Allows you to set the time interval in milliseconds between individual characters trans-
mitted from the scanner to the host. A high setting will significantly slow down commu-
nications. For example, a 200 setting will result in a 1/5 second delay between each
character that is transmitted.
