PT-Series HD Camera Installation

Note

1.6.6 Serial Communications Settings - Hardware DIP Switches

The camera has two blocks of DIP switches that are used to configure the serial communications

settings. One block of switches has 8 switches and is used to set the serial address (or ID) of the

camera. The other block of switches has 10 switches and is used to set baud rate, hardware protocol

(RS-232 or RS-422), serial protocol (Pelco D or Bosch), and Software Override.

The figure below shows the locations of dip switches SW102 and SW103.

When the Software Override DIP switch is set to the Off position (as it is by default), all of the other

DIP switches will be ignored, and configuration changes must be made through software. If the

switch is set to the On position, all configuration settings related to serial communications are made

with the DIP switches, and changes that are made via software (with a web browser) will be ignored.

Serial Address: Use the block of switches on the left (SW102) to set the serial address of the

camera. The available range of values is from decimal 1 to 255. The dip switches are interpreted as

a binary number, with switch 1 representing the least significant bit (the switches are in the reverse

order of the bits). For convenience, a table of serial addresses and their binary equivalents is

included at the end of the manual. Refer to

The serial communications parameters for the PT-Series HD camera are set or modified either via

hardware DIP switch settings or via software, through a web browser interface. A single DIP switch

(SW103-9), Software Override determines whether the configuration comes from the hardware DIP

switches or the software settings.

The DIP switches are only used to control serial communications parameters. Other settings, related

to IP camera functions and so on, must be modified via software (using a web browser).
