Commands
7-33
Reader response:
Done
If the reader is configured for software flow control (XON/XOFF), it stops transmit-
ting if it receives an XOFF character (host software command 13H). It does not
resume transmitting until it receives an XON character (host software command 11H).
If the reader is configured for hardware flow control (RTS/CTS, request to send/clear
to send), it stops transmission if it detects that the CTS line is no longer asserted. It
resumes transmission when this line is asserted again.
Note: TransCore recommends that XON/XOFF flow control be disabled while using
the ECP.
6170 Disable Echo Mode
Command #6170 disables the reader’s echo of received host commands. If operating
in basic protocol or data inquiry protocol, the reader echoes by default. As the reader
receives a host command, it echoes each character of the command. Once the entire
command has been received and processed, the reader transmits its response. If echo
-
ing is disabled with command #6170, the reader does not echo the command, but
only transmits its response. The reader never echoes while in ECP or download mode
operation.
Reader response:
Done
6171 Enable Echo Mode (Factory Default)
Command #6171 enables the reader to echo received host commands. Command
#6170 disables echo mode.
Reader response:
Done
620N Set Output Control
Command #620N provides direct control of two output lines that may be used to
operate external hardware, such as gates or traffic lights. The value for
N specifies the
output status requested as shown in
Table 7-12. Receipt of any #620N command
automatically disables command #621 Predefined Output Control.
