1 PT-Series Camera Installation
1.6.3 Ethernet Connection
The cable gland seal is designed for use with Shielded Category 6 Ethernet cable.
1.6.4 Serial Connection
For serial communications, it is necessary to set the parameters such as the signalling standard (RS-
232 or RS-422), baud rate, number of stop bits, parity and so on. It is also necessary to select the
communication protocol used (either Pelco D or Bosch) and the camera address. By default, the
serial interface uses Pelco D, RS-422 standard, 9600 baud rate, 8/1/none, and address 1.
Note
Connect the wires of the serial cable as show in Figure 1-3 on page 1-7. When using the RS-422
standard, ensure the transmit pair of the camera goes to the receive pair of the other device, and vice
versa.
Note
1.7 Serial Communications Overview
The installer must decide if the serial communications settings will be configured via hardware (DIP
switch settings) or software. If the camera has an Ethernet connection, then generally it will be easier
(and more convenient in the long run) to make configuration settings via software. Then configuration
changes can be made over the network without physically accessing the camera. Also the settings
can be saved to a file and backed up or restored as needed.
If the camera is configured via hardware, then configuration changes in the future may require
accessing the camera on a tower or pole, dismounting it, and removing the back and so on. If the
camera does not have an Ethernet connection, the DIP switches must be used to set the serial
communication options.

Note
1.8 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.
Typical Bosch systems operate using a biphase connection and the FLIR cameras do not accept
biphase signals directly. It may be necessary to install a biphase converter in order to use the Bosch
protocol.
The terminal blocks for serial connections will accept a maximum 20 AWG wire size.
The serial communications parameters for the PT-Series 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).
