Serial Remote
In some installations, a serial device such as a keyboard, joystick, or other device is used to
control camera functions such as pan/tilt or zoom. A serial device can also be used to access
functions that are specific to thermal cameras, such as changing the polarity from white hot to
black hot. Refer to section 4.6.1 "Serial Extensions" on page 4-7 for additional information.
The Serial Remote settings are used to configure the serial communication parameters when
the camera is controlled with a serial device. The Serial Remote option is not available on some
cameras that do not have serial communication interfaces.
The settings will take effect if the Software Override DIP switch is set to Off (the default),
allowing software settings to control the camera. If the switch is set to On, software
configuration changes through the web browser will have no effect. For more information about
the DIP switches, refer to the camera installation manual.
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.
On the Serial Remote Configuration
page, the pull-down in the upper right
allows configuration of three serial
devices: 0, 1, and 2. Device ID 0 is
used as a switch to select either Pelco
D or Bosch serial communications
protocol. The actual serial parameters
are configured for either Device ID 1
(for Pelco D) or Device ID 2 (for
Bosch).
With Device ID 0 selected, set the
Serial Remote Protocol to either Pelco
D Serial Remote or Bosch Serial Remote. Ensure the Enabled parameter is set to Yes. If
necessary, click Save to save the changes.
If the Pelco D protocol is to be used, select Device ID 1 and
wait for the page to refresh, and then configure the
Remote Port Settings such as Speed (baud rate), Data
Bits, Parity and Stop Bits. Set the Address parameter to
the appropriate Pelco address.
If the Preset Map File is set to yes, then presets can be
used to access certain settings that are specific to the FLIR
thermal camera, such as switching between White Hot and
Black Hot settings. See section 4.6.2 "Preset Map File" on
page 4-7 for information about the Preset Map File.
The Initial Selected Camera is used to designate which camera (IR or DLTV) in a multi-sensor
camera is selected as the initial Active camera. Select the appropriate Hardware Protocol (RS-
422 or RS-232).
