Communications Protocol

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 communications 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 "Communications Port, Select COM Port" 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.
Here are the parameters you can set for each communications protocol:
Multi-Drop protocol parameters
• Baud rate, parity, and data bits
• Transmit abort timeout
•
PC Standard protocol parameters
• Baud rate, parity, data bits, and stop bits
