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 dierent 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 congure the RS-485 settings or communication specications (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.
