Note: When connecting more than two devices to a notebook computer with Bluetooth

wireless technology, we suggest that you disable the Bluetooth

Power Saving
function for a more reliable connection.
AUTHENTICATION
When the authentication and PIN code are changed on the RFID Reader, you have to remove the
RFID Reader from the paired device list (called unpairing) and go through the whole process to
re-establish the connection.
Command:
#@bt_secure?\r
Purpose Get Bluetooth

With 1800 authentication disabled, the 1800 reader can pair with multiple Bluetooth
®
devices.
Successful pairing records will be kept for future re-connection without authentication process.
With 1800 authentication enabled, the reader can keep only one pairing record. If the reader pairs
with device A and then pairs with device B, the pairing record of device B will be kept. If device A
wants to connect to the reader, the pairing process must be made again.
If the pairing record on a paired device is cleared, the paired device won’t be able again to pair
with the reader whose authentication is enabled; to solve this problem, users are supposed to
manually clear the pairing record on the reader by issuing “#@BT_RESET” command or using the
function key combination.
PIN CODE
RFID Reader allows up to 16 characters for a PIN code. If the PIN or passkey is incorrect, any
connection requirement will be rejected by RFID Reader. See step 8 in
3.1.3 Bluetooth® HID and
SPP Slave. By default, the PIN code value is “0000”.
