Response Timeout
3-18 MS-9 Scanner User’s Manual
Response Timeout
Intercharacter Delay
Usage: Used only when a response is required from the host. While in Multi-
drop, if the scanner does not receive an ACK or NAK from the host after
sending polled data, it will act on a fault. The scanner can be set to wait
indefinitely by setting Response Timeout to zero.
Definition: Time the scanner will wait before timing out if ACK, NAK, and ETX are
enabled, and a host response is expected.
Serial Cmd: <K143,response timeout>
Default: 2 (x 10 = 20 mS)
Options: 0 to 255 in 10 mS increments (0 to 2.55 seconds)
(A zero (0) setting causes an indefinite wait.)
Usage: Used only when a host cannot receive data quickly enough and there is
enough time between symbols to allow data to be completely transferred.
It is rarely used since any setting other than zero will slow down commu
-
nications. For example, a 200 setting will result in a 1/5 second delay
between each character that is transmitted.
Definition: The time interval in milliseconds between individual characters transmit-
ted from the scanner to the host.
Serial Cmd: <K144,intercharacter delay>
Default: 0
Options: 0 to 255 (in milliseconds). Zero (0) causes no delay between
characters.
