2.1 Module Connection to SCT-2200 Transmitters
2.1.1 RS-485 Connection
It is possible to connect up to 32 devices on the same RS-485 line.
Figure 2-1. Electrical Diagram of RS-485 Connection
• Use an STP (Shield Twisted Pair) cable to make the connection. STP Cable - 2x24 AWG twisted and shielded pair(s).
Single shielding for each pair is provided through foil wrap and total shielding through conduit.
• Using the appropriate cable for RS-485 connections, the maximum line length is about 1200 meters.
• As cable length increases, the cable capacity ( near 50pF/m) becomes a major factor in power consumption and
increases as speed increases.
• This means that the maximum distance cannot be covered with the maximum possible speed. For approximate values,
consult the table below:
When the SCT-1000 Ethernet is set up to use Modbus TCP, it is only capable of communicating with one SCT2200.
Making an RS-485 Connection
1. Verify that the grounding satisfies the SCT-2200 requirements. See the SCT-2200 Operating Manual (PN 183522).
Connect all of the digital and analog masses and power circuits to the grounding bar, and connect the grounding bar to
the earth ground.
2. The shielding can be connected to a single point in the network (as shown in Figure 2-1) or at both ends, however, it is
important that all the devices have the same potential in order to avoid forming ground rings.

3. Connect two termination resistances equal to the characteristic impedance of the cable (typically 120 Ω, see
Figure 2-1 on page 3). Only connect the two devices at the two ends of the ring connection (Example: indicator and
last device). The terminal resistance is not supplied with the ports of the indicator.
4. The difference of potential between the A(+) and B(-) terminals in rest conditions (Example: in set-up phase) must be
at least 0.2 V.
5. To create a resistive divider which maintains this difference of potential when all the transmitters are disabled, insert in
the RS-485 port where the termination resistances are located the polarization or fail-safe resistances (RFS in
Figure 2-1 on page 3). The value of these resistances is between 390 Ω and 2.2 kΩ.
The value of these resistances must be greater than the value calculable through the formula below:
Vdc = The power supply voltage of the line
Req = The overall resistance to the A(+) and B(-) between the lines, supplied by the parallel of the two termination
resistances and all the input resistances of the devices connected to the bus.
Example:
Assume that a connection has 120 Ω as termination resistance and 32 connected devices, each with an input
impedance of 12 kΩ. The Vdc power supply is 5 V, and calculate Req to be about 52 Ω. After plugging these
numbers into the equation, RFS must be at least equal to 624 Ω.
If connecting with non-RLWS devices:
• Be aware that lines may be marked differently. Generally the A/B markings correspond to the +/- and HI/LO markings,
but this is not always the case. Therefore if the device does not function properly, try inverting the connections.
2.2 Electrical Diagrams
2.2.1 SCT-1000 Ethernet Module
Once the SCT-1000 Ethernet module is integrated into the SCT-2200 indicators, it can be connected to an external Ethernet
cabling using an external RJ-45 connector. We recommend using a network surge suppressor (PN 72682) wired through a cord
grip with the RJ-45 socket left outside of the enclosure.

2.3 Configuring PC to communicate with Module
2.3.1 Setting the IP address for Ethernet connections
Both the SCT-2200 Wi-Fi and the SCT-1000 Ethernet module have Ethernet capability and will be automatically recognized
when hardwired into a network.
• The default IP address of the SCT-2200 Wi-Fi is 192.168.16.254.
• The default IP address of the SCT-1000 Ethernet is 192.168.16.205.
The computer Ethernet port must belong to the same class of network for the module to be recognized on the network (in this
case, the network must have an IP address of the type 192.168.16.xxx). To modify the IP address in Windows 10 follow these
steps:
1. From the Start menu, select Settings. See step 1 in Figure 2-4.
2. In Windows Settings, select Network and Internet. See step 2 in Figure 2-4.
3. In Network and Internet, select Ethernet, then select Change Adapter Options. See step 3 in Figure 2-4..

3.3.2 Tunneling Mode
Tunneling mode allows the Ethernet protocol to overcome the limits of serial communication by creating a virtual connection. This
mode requires the use of two modules and their respective UDP ports.This can only be performed in Serial to Ethernet mode.
Tunneling mode can only be set up between the same port on each module, i.e., Port0-Port0 or Port1-Port1.
To set up tunneling mode:
1. Navigate to each module’s Port 0 or Port 1 Settings page.
2. Insert the Local UDP Port Number of module 1 into the Remote UDP Port Number field of module 2.
3. Insert the Local UDP Port Number of module 2 into the Remote UDP Port Number field of module 1.
4. Ensure the Make these settings permanent box is checked, then click Save.
Example:
Do not change the other UDP parameters.
To disable tunneling mode, set the UDP Remote IP Address field to 0.0.0.0 for both modules.
3.3.3 Double Tunneling Mode
Double tunneling mode functions the same as single tunneling mode, but can manage two virtual connections at the same time.
This mode requires the use of two modules and their respective UDP ports. This can only be performed in Serial to Ethernet mode.
Double tunneling mode can only be set up between the same ports on each module, i.e., Port0-Port0 and Port1-Port1.
To set up double tunneling mode:
1. Navigate to each module’s Port 0 Settings page.
2. Insert the Local UDP Port Number of module 1 into the Remote UDP Port Number field of module 2.
3. Insert the Local UDP Port Number of module 2 into the Remote UDP Port Number field of module 1.
4. Ensure the Make these settings permanent box is checked, then click Save.
5. Repeat steps 2-4 for each module’s Port 1 settings.
Example:
Do not change the other UDP Parameters.
