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 conflicts.
