Avolites LTD Engineering Change Notice ECN title Sapphire Touch Impedance Matched Ethernet ECN Number ECN-206 Related Product(s) All Sapphire consoles before SN 300 Date / Author 27/06/2016 Toby Roworth Reasons for ECN Ethernet link quality can degrade due to poor signal integrity Parts required Assembled TNS etherCon snapoff board Tools required PZ2 screwdriver, PZ1 screwdriver, 5.5 mm socket/nut driver Estimated time 15 Minutes Background: Sapphire Touch consoles originally shipped without impedance matched tracks on the etherCon output board. This can lead to link quality issues, especially evident on Gigabit networks when using TitanNet. 1. Remove the 6 screws securing the back panel. 2. Remove the back panel lid. 3. Unplug the two RJ45 connectors going into the Ethernet board. ECN 206 Sapphire Touch Impedance Matched Ethernet, 27/06/2016 - 1 - 4. Remove the 4 screws holding ethernet sockets 1 and 2. 5. Remove the M3 nut holding the earth wires in place, next to the DMX boards. This may be easier if the nearby RJ45 and DVI cables are temporarily removed. 6. Withdraw the ethernet board. 7. Fit the new etherCon board (identified by the wiggly tracks on its underside) using the 4 screws previously removed. 8. Run the earth wire behind the two hex pillars, put the crimp over the earth stud and refit the M3 nut, ensuring all four earth wires are in place, and in contact with one another. (Note that consoles fitted with a DC-UPS will have a fifth earth wire on the stud, which also needs refitting). 9. Plug the RJ45 connectors back in, such that the numbers match the labels on the back panel. 10. Replace the back panel lid and
