Flir ThermovisionMDSeries Installation Manual

							432-0010-00-12 Rev 100 — MD-Series Installation Guide 41
 MD-Series Reference
By design, the camera image will freeze momentarily on a periodic basis during 
the flat field correction (FFC) cycle. A shutter activates inside the camera and 
provides a target of uniform temperature, allowing the camera to correct for 
ambient temperature changes and provide the best possible image. Just prior to 
the FFC, a small green square will appear  in the upper left corner of the screen.
Note:  If you have a JCU, pressing and holding the COLOR button causes the 
thermal camera to do an FFC operation.
Multiple Cameras and/or JCUs on a single network
You can configure the system with multiple  cameras and multiple JCUs on the 
same network. More than one JCU can be used to control a given camera. The 
camera will respond to commands from both  JCUs in the order the commands are 
received across the network. Unpredic table behavior may result from users 
sending conflicting commands from separate JCUs (for example, one user selects 
white hot and the other selects black hot).  In general, the camera will respond to 
the last command received and there is no way to set priority, given that IP 
networks use a “best effort” delivery protocol.
Note:  This behavior is true only of JCUs. If you are using the Web interface to 
control the camera with a browser on a PC or smartphone, a message displays 
prompting you to release control before the other Web device assumes it. 
On Screen Messages
In some circumstances, a status or alert message may appear on the video 
screen. This section describes the mess ages and the appropriate actions that 
may be necessary.
Loading, please wait…
Indicates the camera has power and is booting up. No action is needed; the 
message will be removed when ca mera is ready for operation. 
Reconnect network, now...
Indicates the camera has detected a loopback termination on the Ethernet RJ45 
connector and has reverted to the Factory Default network settings. Remove the 
Ethernet RJ45 loopback termi nation adapter. The camera will then continue the 
startup process under the factory default network configuration (with DHCP 
dynamic IP addressing).
No Network…
Indicates the camera has lost connection with a previously available network. 
Normally, when the camera is on a network, the IP address of the camera 
displays. If the network connection is interr upted, this message displays instead.

Restoring the Factory Network Settings
In some cases, it may be necessary to restore the network settings of the camera 
to the original factory settings. At each  power up, the system transmits a packet 
and then checks to determine if that sa me packet has been received. Detection 
of the received packet indicates the camera has a custom loopback connector 
installed on its Ethernet interface. The detection of the loopback packet cues the 
camera to restore factory defaults and to revert to the same configuration and 
behavior as when the camera left the factory.
The following table describes the loopback connector.
The RJ45 loopback termination ties pin 1 to  pin 3, and pin 2 to pin 6. The other 
pins are not connected.
Pin  Signal Tied to pin 
1 Transmit + 3
2 Transmit -  6
3 Receive + 1
4 Unused N/A
5 Unused N/A
6 Receive 
-2
7 Unused N/A
8 Unused N/A
