52 Magellan™ 3300HSI
RS-232 Interface Features (continued)
Host Echo
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 necessary. If, for example, one of the devices in
the chain is a terminal where someone is entering data while another person is
simultaneously 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
). The scanner can be set to observe
this delay before sending its data in order to avoid RS-232 transmission con-
flicts.
