Network Wiring and Configuration 

XJ Scroll Condensers connect to the E2 with the One-Way Communication Board using 

RS485 MODBUS. 

Connect the XJ Scroll to the MODBUS network as shown in 

Figure 2

. Connect the network 

cable to the three-terminal connector on the E2 COM port that has been configured as MOD-

BUS port (COM 2, 4, or 6).
