5.5.1 Using the LOI
1.
Plug the LOI cable into the LOI RJ-45 connector of the ROC800.
2.
Connect the LOI cable to the D-Sub 9 pin (F) to RJ-45 modular
converter.
3.
Plug the modular converter into the COM port of the PC.
4.
Launch ROCLINK 800 software.
5.
Click the
Direct Connect
icon on the ROCLINK 800 tool bar.
6.
Configure communication for the other built-in and modular
communications, I/O modules, AGA meter parameters, and other
configuration parameters.
5.6 Ethernet Communication
The Ethernet communication port in the ROC800 supports TCP/IP
protocol communication using the IEEE 802.3 10Base-T standard. One
application of this communication port is to download programs from
DS800 Development Suite Configuration Software.
Default TCP/IP
The ROC800 uses the following factory defaults:
TCP/IP: 10.0.02
Gateway: 10.0.0.1
Subnet Mast: 255.255.255.0
The Ethernet communication port uses a 10BASE-T Ethernet interface
with an RJ-45 connector. Each Ethernet-equipped unit is called a
“station” and operates independently of all other stations on the network
without a central controller. All attached stations connect to a shared
media system. Signals are broadcast over the medium to every attached
station. To send an Ethernet packet, a station listens to the medium
(Carrier Sense) and when the medium is idle, the station transmits the
data. Each station has an equal chance to transmit (Multiple Access).
The Medium Access Control (MAC) mechanism embedded in each
station interface determines access to the shared medium. The MAC
