Port Configuration Parameters
Use this procedure to set port configuration parameters using the terminal emulation program. Refer to
sections “100N Select Baud Rate” on page 5–59 through “102N Select Parity” on page 5–60.
To set baud rate
1. Ensure that the host device is in command mode.
2. Enter Command #100N and press ENTER.
To set stop bits
1. Ensure that the host device is in command mode.
2. Enter Command #101N and press ENTER.
To set parity
1. Ensure that the host device is in command mode.
2. Enter Command #102N and press ENTER.
Communications Protocol
Use the following procedures to set communications protocol. Refer to sections “610 Select Basic
Communication Protocol (Factory Default)” on page 5–74 through “614N Select Software Flow Control
Option” on page 5–75 for more information.
Caution
Do not switch to ECP (Command #611) unless the host is prepared to acknowledge
each reader transmission.
To select a communications protocol
1. Ensure that the host device is in command mode.
2. Enter Command #610 to select basic protocol (factory default) or Command #611 to select ECP
and press ENTER.
Software Flow Control
The host can enable or disable software flow control with Command #614N Select Flow Control Option.
The host can use software control characters (XON/XOFF) to interrupt reader transmissions. When the
reader is configured for software flow control, it stops transmitting if it receives the XOFF character from
the host (host software command 13H). It resumes transmitting only when it receives the XON character
(host software command 11H) from the host. If software flow control is not needed, the reader should be
configured for no flow control (#6140 Disable Flow Control).
Note: TransCore recommends that XON/XOFF software flow control be disabled while using the
ECP.
Use the following procedure to set software flow control parameters using the terminal emulation program.
Refer to section “614N Select Software Flow Control Option” on page 5–75 .
