4. Repeat Step 3 for each controller you are connecting to the Ethernet network.
Each device has its own section in VSMain.ini. The sample below shows settings for the
second controller added to VSMain.ini.

#Devices=1
Device1=DCM
Device1IPAddress=[IP address of the controller]
5. When you are finished editing VSMain.ini, save your changes and exit Notepad.
a. Click the File menu in Notepad.
b. From the File menu, select S
ave.
c. From the File menu, select Ex
it.
VSMain.ini is now ready to support an Ethernet network. The new settings take effect the next time
you start Visual Supervisor.
Using Ethernet Network Cables
The type of Ethernet cable you need to connect the CS4000 Mini Controller with Ethernet to the Local
Area Network (LAN) is known as 10Base-T. The name is an Institute of Electrical and Electronics
Engineers (IEEE) standard identifier for this type of cable. The “10” refers to the transmission speed
of 10 million bits per second (Mbps). The “Base” refers to baseband signaling which means only
Ethernet signals are carried on this cable and the “T” represents twisted-pair.
When you look at an Ethernet cable, you see four pairs of wires, each pair twisted together into a
double helix formation. This is how the cable receives its designation as a twisted-pair. The twisted
pair cabling combats interference and helps keep the integrity of signals sent down the cable. The
double helix configuration produced by twisting the wires together creates symmetrical noise signals
in each wire that cancel each other out, thus reducing the noise level and interference of the signal to a
minimum.
CAUTION! It is extremely important to maintain the twisted wires of the
Ethernet cable to within half an inch or less of their
termination point.
Table 5-1 shows the pinout used for the RJ-45 modular jack attached to both ends of the 10Base-T
cable that connects the controller to the network hub. It uses the IEEE T-568B standard wiring system.
