Baud Select (Bx)
Function
Selects a baud rate
listed in Figure 27.
Remarks
When the meter recognizes a valid Bx
command, its baud ra
te is immediately
changed. (The contro
ller is assumed to
be transmitting at
the new rate; other-
wise sending commands wo
uld not be possible.)
This command overrides
the DIP switch setting.
Xmission Flow Control (XO/XF)
Function
Enables or disables th
e XON/XOFF flow control.
XO enables flow control.
XF disables flow control.
Remarks
When data is being sent from the powe
r meter to the computer and flow con-
trol is enabled, data transmission will be suspended when the XOFF character
(hexadecimal 13) is sent by the comp
uter. Transmission will resume when
XON (hex 11) is sent by the computer.
When data is being sent from the comput
er to the power meter, XOFF will be
sent to the computer when the input buff
er fills up. XON will be sent to the
computer when the buffer has emptied.
