message size
on size alone. When the maximum receive message size number of
characters is received the message is terminated. The default value is 8192.
RTU port baud rate
The RTU port baud rate controls the rate of data to and from the RTU port.
Valid baud rate values include: 300, 600, 1200, 2400, 4800, 9600, 19200,
38400, or 57600. The default value is 9600 baud.
RTU port parity
The RTU port parity defines the character based error checking. Valid
parity values include: NONE, EVEN, or ODD. The default value is
NONE.
RTU port data bits
The ‘RTU port data bits’ defines the number of data bits of the RTU data.
Valid data bits are 7 or 8 bits. The default value is 8 bits.
RTU port stop bits
The ‘RTU port stop bits’ defines the number of stop bits per characters.
Valid stop bits are 1 or 2 bits. The default value is 1 stop bit.
RTU bound flow
control
The RTU bound flow control allows the RTU to throttle data from the SDT
5000. Valid flow control values are: NONE, RTS, or XON-XOFF. The
default value is NONE.
If the RTU bound flow control is set to RTS when RTS is dropped the
SDT 5000 stops sending data to the RTU. When the RTU RTS is raised the
SDT 5000 resumes sending data to the RTU.
If the RTU bound flow control is set to XON-XOFF and the RTU sends an
XOFF the SDT 5000 stops sending data to the RTU. When the RTU sends
XON the SDT 5000 resumes sending data to the RTU.
MET bound flow
control
The MET bound flow control allows the MET to throttle data to the SDT
5000. Valid flow control values are: NONE, CTS, or XON-XOFF. The
default value is NONE.
If the MET bound flow control is set to CTS and the SDT 5000 cannot
keep up with the flow of data it will drop CTS. The RTU is supposed to
suspend sending data until the CTS line is raised.
If the MET bound flow control is set to XON-XOFF and the SDT 5000
cannot keep up with the flow of data from the RTU it will send the RTU an
XOFF. The RTU supposed to suspend sending data until the SDT 5000
sends an XON.
Data carrier detect
(DCD) mode
The DCD mode controls the output of DCD with the following values:
ASSERT, DEASSERT, CPU POWERUP, OPERATIONAL, or
CONNECTED. The default value is ASSERT.
If DCD mode is ASSERT the DCD line on the RTU port will be asserted
when the SDT 5000 is powered on.
If the DCD mode is DEASSERT the DCD line on the RTU port will be
deasserted when the SDT 5000 is powered on.
