• The RS-485 connection can be either one-to-one or one-to-N. A maximum of 32 Units (including
the host computer) can be connected in one-to-N systems.
The maximum total cable length is 500 m. Use shielded twisted-pair cable.
Note: The E5CC-U does not support communications.
 Connecting Short Bars
On the E5DC, you can use a Y92S-P11 Short Bar to connect the power supply or communications.
Connect the Short Bar to the power supply screw terminals or the screw terminals for communications.
