NF BC Networking the Reader
Configuring the Reader for Communications
6
Prepare the reader to communicate with another device by performing these
steps for every reader COM port that you want to communicate through:
1. Choose a COM port to configure. Decide which communications
application, communications protocol, and protocol handler to use for that
COM port. For help, see “Working With JANUS COM Ports” and
“Planning the Network Connection” earlier in this chapter.
2. Select the COM port.
3. Configure the communications protocol(s) for the COM port.
4. Activate one communications protocol for the COM port.
5. Load the protocol handler for the COM port.
6. If you do not load a protocol handler, you may need to specify a value to
restore the UART FIFO control register for the COM port.
7. Connect the reader to the device it will communicate with.
8. Repeat Steps 1 through 7 for every COM port you want to configure.
Steps 2 through 7 are described in detail in the next sections.
Selecting the COM Port
Begin configuring the reader by selecting a COM port. All changes you make
in the reader’s configuration that relate to communications are applied to the
selected COM port until you select another COM port.
To select the reader’s COM port
1. Decide which reader COM port to use. For help, see “Identifying JANUS
COM Ports” earlier in this chapter.
2. Select the reader’s COM port with the Communications Port, Select COM
Port command. The reader will apply all subsequent changes in its
communications configuration to the selected port.
For help, see “Communications Port, Select COM Port” in Chapter 12.
