4.13 RS-485 / RS-422 Network Recommendations
FISO recommends the use of a two pairs, shielded twisted pair cable for RS-485 mode and a three pairs,
shielded twisted pair cable for RS-422. The extra pair will be used for ground.
The cable should have a 120Ω
line impedance.
If the EasyGrid Base is at one end of the RS-485 cable, you must place an End of Line resistor. You can use the
integrated EOL resistance with the OFF / EOL dip switch.
FISO recommends polarising the link in one place. You could use the integrated pull up and pull down
resistors of the EasyGrid Base. To do so, place the Pull Up and the Pull Down dip switch to the top.
IMPORTANT
When linking more than 1 device together off the same network bus line, make sure that all
units have a different network IDs in order to avoid communication conflicts.
The factory-defined address for all units is one “1”.
