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
8
.
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. Bye 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, RS-485 is used to control a PAN/TILT device,
such as an external camera enclosure to perform PAN and TILT movement.
