3.3.3 Using the LOI
1.
Plug the LOI cable into the LOI connector on the DL8000 CPU.
2.
Connect the LOI cable to the D-Sub 9 pin (F) to RJ-45 modular
converter.
3.
Plug the modular converter into the PC’s serial COM port.
4.
Launch ROCLINK 800 software.
5.
Click the
Direct Connect
icon.
6.
Configure communications for the other built-in and modular
communications, I/O modules, AGA meter parameters, and other
configuration parameters.
3.3.4 Ethernet Communications
The Ethernet communications port in the DL8000 allows TCP/IP
protocol communications using the IEEE 802.3 10Base-T standard.
One application of this communications port is for downloading
programs from DS800 Development Suite Configuration Software.
The Ethernet communications 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).
Access to the shared medium is determined by the Medium Access
Control (MAC) mechanism embedded in each station interface. The
