Installation Variations
Digital Setpoint Source — RS485 Network,
RS232 to RS485 Converter (TESCOM™ Model #85061) (cont.)
Each ER5000 in the network must be assigned a unique Node
Address. All ER5000s are assigned a default Node Address of 250;
therefore, the addresses must be changed to allow them to all
communicate on the network.
The Node Address can be changed as part of the setup procedure
or at any time afterwards using The Congure Tab.
Refer to To set up the ERTune™ program to work with the ER5000
and The Congure Tab for more information on how to modify the
Node Address of the ER5000 using the ERTune™ program.
Repeat this process for each ER5000 in the network. Be sure to
give each controller a unique Node Address within the network.
You may leave one ER5000 at the default value.

The RS232 to RS485 converter requires direct wiring to an
external power supply, so it must be connected to the ER5000’s
power supply wiring. The violet wire (Pin 7) connects to the
+24V DC terminal and the gray wire (Pin 8) connects to the
ground terminal.
