You will use each protocol handler with a specific communications protocol:
Note: You do not load a protocol handler if you choose No Protocol as your
communications protocol. For example, if you decide to use the Interlnk
communications application, you do not need a communications protocol or protocol
handler, so you choose No Protocol and do not load a protocol handler.
PHIMEC and PHPCSTD are not loaded when you boot your reader because
they use a lot of conventional memory. RFPH is loaded when you boot a
JANUS 2010 with an RF back.
When you load a protocol handler that corresponds to the active protocol, the
active protocol tells the protocol handler how to communicate. For help, see
"Loading and Unloading a Protocol Handler" later in this chapter.

Configuring the Reader for Communications

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
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
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.
