2.7.18 Ethernet (Direct Connect)
The ethernet port is primarily used for direct connections
with a laptop. Through the port you can upload/download
configurations, download history, view live data, and
upgrade firmware. The ethernet port is located on the left-hand side of the box in a connector with a
waterproof cap. The cap must be in place whenever the port is not in use. Use the supplied
Ethernet Crossover Cable
(P/N 991-05047661.88)
for PC connections.
2.7.19 LAN Connections
The 3D TRASAR controller can be connected to a LAN system, however, it is required that a Router
(P/N 060-TR5270.88)
be used to isolate the controller from the rest of the LAN system. Processing
extraneous broadcast messages will significantly impact controller operation. Refer to Appendix E
for more details or call 630-305-CHEM for assistance.
2.7.20 SCADA Connections (Modbus RTU)
The 3D TRASAR controller is equipped to handle either a single RS-232 or RS-485 modbus
connection. Refer to Appendix E for more details.
