COMMENT

2. Transmits command acknowledgement (‘^’ 5EH) if successful.
3. Waiting for and detect approaching card.
4. The LED1 will light on and then turn off after a successful reading or a
MIFARE card being detected.
NOTE
1. After an
Arm to Read
command is received and acknowledged the only
valid commands that will be accepted for execution are: <ESC> “Abort”
and ‘$’ “Status”.
2. Reader will NOT send out track data automatically; the host should
issue the ‘Q’, ‘R’, ‘S’, ‘U’ commands to get the corresponding track data.
3. In the Self-Arm mode, it is not necessary to send this command. If this
command is sent, it will temporarily override the Self-Arm mode.
