Parity Bit:

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 identier 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 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.
