Changing the System Settings — RS485 Settings
The RS-485 is a serial communication method for computers and devices. The RS-485 is used to
control a PAN/TILT device, such as an external camera enclosure. Click the RS-485 button on the left
side of the “System” page to enter the “RS485 Settings” page.
NOTE: Check “Support PAN-TILT” box and a RS-485 control panel will appear on the left
side of the Live View page.
Description of function keys:
Support PAN-TILT:
When enabling Support PAN-TILT, a control panel will be displayed on
the Live Video page allowing control for an external camera enclosure
through the RS-485.
Protocol:
Select a protocol type from the pull-down menu.
ID:
Choose an ID between 1 and 255. This ID is the identifier for each
RS-485 device.
Baud Rate:
Choose
between 2400 and 115200 bps. This is a speed measurement
for communication between a transmitter and receiver, indicating the
number of bit transfers per second. A higher baud rate will reduce the
distance of the two devices (transmitter and receiver).
Data Bits:
Either 7 or 8. It is a measurement of the actual data bits in a
transmission. By default, the value is 8.
Parity Bit:
Choose
from
No
, Even, and Odd. This is a simple form of error checking
used in serial communication and you may use no parity. For even and
odd parities, 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
