Ethernet/LAN (ENET) Connector (Optional) 
The power supply also can be programmed from a remote terminal 
using the Ethernet (ENET). If your power supply is configured with the 
Ethernet option, set-up instructions differ between the 850 Watt models 
and the 1500 and 1700 Watt models. 
For the XG/XTR 850 Watt power supply with the MEA option, see 
SETTING UP XG/XTR 850 WATT MODELS in Section 6 
“Communications Options” of this manual). Note the the MEA option 
instructions in the manual are for reference only. The MEA option is no 
longer available. 
For the XG/XTR 1500 and 1700 Watt power supplies with the MEB 
option, see SETTING UP XG/XTR 1500 and 1700 WATT MODELS in 
Section 6 “Communications Options” of this manual. 
For connecting the power supply to ENET, use a LAN RJ-45 and RJ-45 
STP. Use a standard RJ-45 and RJ-45 cross-cable, Cat 5. 
 
Multiple Power Supply Connections to RS-485 Bus 
Up to 30 units may be connected to the RS-485 bus. The first unit 
(master unit) connects to the controller via any appropriate port, and the 
other units (slave units) are connected with the RS-485 bus via the J6 
connector. All units connected together should also have unique 
multichannel addresses. 
A standard straight-through RJ-45 Ethernet network cable can be used to 
provide the connection between the power supplies. See Figure 5-13.
