TERMINAL
RESISTOR FOR TWIN PID |
|
RS485 linking bus is generally formed by a
twisted pair + shield that connect several devices. In order to minimize
reflections, the first and the last net devices should have a terminal
resistor linked in parallel mode to the line.
Easy terminal already has a terminal resistor of 120 Ohms on "2" and "3"
clamps (+ and - RS485); so, the only thing to do is to link the first
and the last TwinPID RJ11 plugs of the RS485 net to this device.
