Communications Port, UART Restore (continued)
2. Scan two bar codes for data from the "Full ASCII Bar Code Chart" in
3. Scan this bar code:
Communications Protocol
Communications Protocol determines how the reader communicates with the
host through the DTE interface of the selected communications port. You can
configure a different communications protocol for each communications port.
Even if you use the same protocol, you must configure each communications
port separately. You can also configure a different protocol for each
communications port.
Before configuring a protocol, you need to select the communications port. For
help, see the "Communications Port, Select COM Port" command earlier in this
chapter.
To configure the communications protocol
1. Configure the protocol.
2. Activate the protocol.
After you activate the protocol, you need to load the protocol handler, set the
UART FIFO control register, and connect the device. For help, see
"Configuring the Reader for Communications" in Chapter 6.
Configure
Purpose:
Configures the communications protocol for the selected communications port.
The reader assigns all subsequent protocol configuration changes to the
selected communications protocol. Next, set the parameters, such as baud rate
or data bits, for the communications protocol.
Note: You cannot reconfigure some of the protocol characters for User-Defined if User-
Defined is active. If User-Defined is the active protocol, set the active protocol to None.
Once you configure User-Defined protocol, reactivate the protocol.
