Host Echo - Datalogic Magellan 8300 Product Reference Manual

RS-232 Host Echo
NOTE
202
When enabled, this feature passes all data through the scanner to
the host as it comes in. This feature is used for applications where
"daisy chaining" of RS-232 devices onto the same cable is neces-
sary. If, for example, one of the devices in the chain is a terminal
where someone is entering data while another person is simultane-
ously scanning a bar code requiring transmission to the host, the
scanner will wait for the RS-232 channel to be quiet for a specified
period of time (set via RS-232 Host Echo Quiet Interval on page
203). The scanner can be set to observe this delay before sending
its data in order to avoid RS-232 transmission conflicts.
When RS-232 Host Echo is enabled, the following features are ignored:
RS-232 Software Flow Control on page 201
Enable on page 212
plus processing of RS-232 host commands.
To enable/disable this feature:
1. Scan the SWITCH bar code.
2. Scan either the enable or disable bar code below. You'll need
to cover any unused bar codes on this and the facing page to
ensure that the scanner reads only the bar code you intend to
scan.
3. Complete the programming sequence by scanning the SWITCH
bar code.
as well as all other ACK/ NAK related operations,
RS-232 HOST ECHO = DISABLE
RS-232 HOST ECHO = ENABLE
and RS-232 ACK NAK
