Aux Port as an RS-232 Input Port
When the auxiliary port is configured as an input port, incoming messages can
be passed on to the host system “as is” or they can be manipulated by the base
prior to sending to the host system. This manipulation may include attaching
prefixes/suffixes to the message and/or data formatting the message.
In order for the base unit to correctly receive a message into the Aux Port, it is
recommended that the incoming message be “framed” by known start and stop
characters. These characters are attached to the message by the input
peripheral, and the base is then programmed to look for these characters. The
base unit is then able to recognize the beginning and end of a message,
eliminating the possibility of partial messages being sent to the host system. Use
the Data Character Selection bar codes (page 3-17) to program these “framing”
characters.
The Auxiliary Protocol section (page 3-11 - page 3-13) is used to configure baud
rate, parity, data bits, stop bits and flow control to match the peripheral protocol
settings.
