When enabling Support PAN-TILT, a control panel
will be displayed on the Live Video page allowing
control through RS-485 for an external camera
enclosure.
Select one protocol type from the pull-down menu.
Range from
1
to
255
, is the identifier for each RS-485
devices.
Range from
2400
to
38400
bps. It is a speed
measurement for communication between a
transmitter and receiver, indicates the number of bit
transfers per second. Higher baud rate will reduce
the distance of the two devices (transmitter and
receiver). By default, the value is
2400
.
Either
7
or
8
. It is a measurement of the actual data
bits in a transmission. By default, the value is
7
.
Either
1
or
2
. It is used to signal the end of communication for a single packet. The more bits used for stop bits, the greater
the lenience in synchronizing the different clocks, but the slower the data transmission rate. By default, the value is
1
.
Choices of
No
,
Even
, and
Odd
. It is a simple form of error checking used in serial communication and you may use no
parity. For even and odd parity, the serial port sets the parity bit (the last bit after the data bits) to a value to ensure that the
transmission has an even or odd number of logic-high bits.
For example, if the data is 011, for even parity, the parity bit is 0 to keep the number of logic-high bits even. If the parity is
odd, the parity bit is 1, resulting in 3 logic-high bits.
You may configure the
RS-485
settings or communication specifications (baud rate, data bit, stop bit, and parity bit)
for your camera. RS-485 is a serial communication method for computers and devices. For your camera, the RS-485
is used to control a PAN/TILT device, such as an external camera enclosure, to perform PAN and TILT movement.
