Calibir 640 GigE Connectors
The Calibir 640 GigE has two connectors:
•
RJ45 Ethernet connector for control and video data transmitted to/from the host computer
Gigabit NIC. The Calibir GigE also supports Power Over Ethernet (PoE).
•
Samtec 10-pin connector for camera power (if not using PoE). See 10-pin I/O Connector
Details for connector pin out specifications.
The following figure of the Calibir 640 GigE back end shows connector and LED locations (for a
description of the possible LED states, refer to the Calibir 640 GigE LED States section).

Preventing Operational Faults due to ESD
Calibir camera installations which do not protect against ESD (electrostatic discharge) may
exhibit operational faults. Problems such as random packet loss, random camera resets, and
random loss of Ethernet connections, may all be solved by proper ESD management.
The Calibir camera when used with a simple power supply and Ethernet cable, is not properly
connected to earth ground and therefore is susceptible to ESD caused problems. An Ethernet
cable has no ground connection and a power supply's 0 volt return line is not necessarily
connected to earth ground.
Teledyne DALSA has performed ESD testing on Calibir cameras using an 8 kilovolt ESD generator
without any indication of operational faults. The following methods, either individually or together
will prevent ESD problems.
•
Method 1: Use a shielded/grounded power supply that connects ground to pin-10 of the I/O
connector. The Calibir case is now properly connected to earth ground and can withstand
ESD of 8 kilovolts, as tested by Teledyne DALSA.
•
Method 2: When using Power Over Ethernet (PoE), Teledyne DALSA strongly recommends
using a shielded Ethernet cable to provide a ground connection from the controlling
computer/power supply, to the Calibir. PoE requires a powered computer NIC, or a powered
Ethernet switch, or an Ethernet power injector.
•
Method 3: Mount the camera on a metallic platform with a good connection to earth ground.
