Parameters
The parameters can be configured via the DB9 RS232 serial port or over Bluetooth. The terminal software TeraTerm or Putty
can be downloaded for free from www.usconverters.com is recommended for configuring the parameters. Please see the
'Setup Guide' for details.
Note 2: Commands cannot be received by the adapters if they are paired/linked, only when the adapter is in command mode.

address. If the adapter is in the Slave mode, this command is a filter condition to accept
the inquiry of the Master device.
Notice: The DEVICE command only works with the CONNECT command to manually
connect two adapters; it does not work in auto mode.

“xxxxxxxxxxxx” is a string of 12 hexadecimal digits.
R Restore the status in which the adapter can connect with any remote address.
? Inquiry the designated address that can be paired and connected.
DISCOVER= This command is used to specify whether the adapter can be discovered or connected by
remote devices.
This command is available only when the adapter is in Slave mode.
N The adapter enters the discoverable mode. If a pair has been made, the original
connection can be resumed. But other remote master device cannot discover this
adapter.
(Default) Y The adapter enters the discoverable mode.
? Inquire the current setting.
ECHO= This command is used to specify whether the adapter echoes characters received from
the UART back to the DTE/DCE.
N Command characters received from the UART are not echoed back to the DTE/DCE.
(Default) Y Command characters received from the UART are echoed back to the DTE/DCE.
? Inquire the current setting.
