Change Sound Pitch “UID PTCH”
With multiple units operating within a confined space, it may be desirable to adjust the pitch of each
unit’s sound emission in order to more easily discern from which unit a sound is emitted. Issuing the
“UID PTCH” command, followed by a number between 31 and 9999 sets the frequency or “pitch” at
which the transponder confirmation tone sounds. The default value is 4096.
Information:
The optimum frequency for the UBS-200L speaker is around 4096
Hz. Setting the tone frequency higher or lower than this value will
also reduce the volume of the transponder read confirmation
tone. The volume is otherwise un-adjustable.
Set Default Power-up Antenna “UID DEFANT”
Use the “UID DEFANT” command followed by the desired antenna port number to change which
antenna port is defaulted to after power-up.
Change Host Baud Rate “UID BD”
The UBS-200L is set to 115200 bps by default. If a different host communication baud rate is desired,
the baud rate can be adjusted by entering the “UID BD” command, followed by the associated
parameter value. Available baud rates and their associated values are summarized in
