Preventing Operational Faults due to ESD

Linea GigE 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 Linea GigE 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.
The following methods, either individually or together, will reduce or prevent ESD problems:
Method 1: Use a shielded power supply. The camera case is now properly connected to earth
•
ground and can withstand high ESD events .
Method 2: Use a shielded Ethernet cable to provide a ground connection from the controlling
•
computer, to the Linea GigE.
Method 3: Mount the camera on a metallic platform with a good connection to earth ground.
•
Method 4: Avoid running the Ethernet cable close to or parallel to AC power lines.
