9. onvention EC Data suggests choosing the darker wire or solid color for and lighter color or striped for Since the bus is bi directional all terminals and both transmit and receive when appropriate Remember RS 485 is not a loop On the ECD485Enet the removable terminals are labeled as T T R R G Due to a space limitation only the transmit signals are echoed on 73 79 the top terminal as D D Gnd If you select the unit in 2W mode only T T and Gnd will work It is also critical that the signal ground be properly connected If your RS 485 bus does not have the 5 ground wire then you should at least connect the signal ground of the connected port of the ECD485Enet to the nearest device s digital ground or use the shield drain wire for a signal ground The ECD485Enet will be damaged over time if this ground is not properly connected Each RS 485 segment requires a 1200hm terminat ing resister at each end assuming your cable has a characteristic impedance of 120 Ohms Therefore a RS 485 system will require at least 2 terminating resisters read the application note for details Below is a drawing of the ECD485Enet showing the location of the jumpers for the RS 485 Those label B are the bias jumpers and the terminating re sister is labeled T 4h Fu
