Acknowledgement from the Host
Host system confirmation may be implemented with a bi-directional interface like
RS-232. In this configuration, when the base unit receives the scanned data
from the scanner and forwards it to the host, the cordless system waits for a
signal from the host that it received the data. (For information on enabling this
feature and using Host Escape commands, see “Host ACK Selection” on page
3-6).
Auxiliary Port
The Auxiliary (Aux) Port of the ST2070 is a bi-directional RS-232 port. When the
Aux Port is configured as the interface (either using the Plug and Play RS-232
code or terminal ID = 000), the Aux Port is set up to be an RS-232 output port.
For all other interfaces, the Aux Port is available as an RS-232 input port.
Peripheral devices can send data into the Aux Port, and the data is automatically
sent out the main port to the host system.
Note: The Auxiliary Port cannot be used as an input when the base is configured
for the following interfaces: Non-Decoded Laser Emulation (HHLC), wand
emulation, and terminal ID = 000 (Aux Port RS-232 output).
Aux Port as an RS-232 Output Port
When the auxiliary port is configured as an output port, use the Auxiliary Port
Protocol section (page 3-11 - page 3-13) to configure baud rate, parity, data bits,
stop bits, and flow control. To change outgoing data prefix/suffixes, set up data
formatting, and change symbology selections, use the programming selections
in Chapter 5.
