Full Gauge TCP-485 User manual

1. DESCRIPTION
The TCP-485 Serial/Ethernet converter allows you to connect Full Gauge controllers with the Sitrad
supervisor software over an Ethernet data network using the communication standard TCP/IP. Nowadays
many companies have Ethernet cabling already installed in their premises. With the TCP-485 converter you
can use your Company installed cabling instead of installing new cabling for the RS-485 network of
controllers. The system is composed of an Ethernet/RS-485 converter connected to the Ethernet network (it
can be Internet, Intranet or a direct connection to the computer) and the Sitrad that connects directly to the
Ethernet/RS-485 converter using TCP/IP. The converter then communicates with the controllers connected
to it and translates the RS-485 electric standard used by the controllers to the TCP/IP communication
protocol used in computer network interconnections.
2. APPLICATION
- Installations that already have an Ethernet network and do not have conditions to run new cabling network.
- Centralize data acquisition from many remote locations in one server without the need to have a dedicated
computer for each remote location.
NOTE: The TCP-485 converter is designed to work only with Full Gauge Controls devices.
3. TECHNICAL SPECIFICATIONS

-RJ-45 connection for connecting with PC using twisted pair cable supplied together with the converter.
- One port Isolated RS-485 for connection to instrument 32, without the need for termination.
- Direct ethernet cable-80cm (without crossover) supplied with the converter.
4. INSTALLATION AND OPERATION (DHCP MODE - DEFAULT
CONFIGURATION)
Connect interface terminals A and B with the respective A and B terminals on the and connecting blocks
instruments;
With the TCP-485 powered on, use an Ethernet cable to connect it to a router (router/switch) in the RJ-45
connectors according to the picture below:
IMPORTANT NOTICE:
If the "LAN" LED indicator in the RJ-45 connector does not light up upon connecting the TCP-485
converter directly to the network adapter of the computer, you may need to use a crossover cable
(not supplied by Full Gauge) or to connect the computer and the converter via a HUB or Switch.

Download a compatible version from: http://www.sitrad.com
Step 1: With the TCP configured, open Sitrad, click on "Configuration" and then on "Options".
Step 2:
In the window that opens, select the option "Use Ethernet communication". Then click on the "Configure
Ethernet" button below.
Step 3: In the window that opens, click on the button "New Converter".
Step 4: In the window that opens, choose the desired option. As an example we will use the option "Search
the network".
Step 5: Once it has been located, select TCP-485 and then click on the button "Register converter", select
version 3 and click "OK".
If the user has the TCP-485 configured with a fixed IP, follow the steps below to connect it to a computer:
5. NETWORK CONFIGURATION IN STATIC IP MODE
For direct connection with a PC, the IP mode must be changed to static. See the step by step procedure :
Step 1:
Using a computer connected to the same network as the TCP-485 (cable or wireless), download
EthernetConfig (Windows version only) from the site:
http://www.sitrad.com/atualizacaoresp.asp
Step 2:
Run EthernetConfig and click on the icon "Broadcast Search". The TCP-485 connected to the network will
be shown after the search is done. See image below:
Step 3:
Click on the "Configuration" menu and click on the box "Network configuration" on the following screen,
change the IP Mode to static, and then click on "save changes".

Step 4:
TCP-485 converter is delivered with the following default values configured:
IP Address:192.168.2.127
Network Mask: 255.255.0.0
Gateway: 0.0.0.0
Configuration Port: 5005
Communication Port: 4000
If your computer is not configured to access the IP range 192.168.2.0 to 192.168.2.255 you need to perform a
direct access to the converter to configure it with some of your computer network IP addresses.
To directly access the converter follow the steps below:
- Connect the converter network cable directly in the computer network card.If the computer is fitted with an
old network card, you may need to use a crossover cable, which is not provided by Full Gauge. Upon doing
this your computer will lose access to the network and the Internet.
- Access your computer network connections:
In Windows XP, open the OS Control Panel, choose “Network and Internet Connections” and then c h o o s e
“Network Connections”.
In Windows 7, open the OS Control Panel, choose the “Network and Internet” option, then “S har ing an d
Network Center” and then, at the menu on the left of the screen, choose the “Change adapter settings” option.
- Right-click the connection you are using and choose “Properties”.
- Select the “TCP/IP Protocol” or “TCP/IP version 4 Protocol” in the list as shown in the screen below.
- After selecting the item, click Properties.
In the following screen, write down the current settings so you can reset back to them later.
- Check the “Use the following IP address” option and configure the fields with the following values:
IP Address: 192.168.2.126
Subnet Mask: 255.255.0.0
Default gateway: 192.168.2.127
- Click OK to exit.
- Click OK in the Properties screen to save the changes.
Your computer is now configured to communicate in the same TCP-485 converter network. Access your
converter through the EthernetConfig application and change the converter IP address to a valid address in
your network.
After performing the configuration in the converter, reset the properties settings of the network card back to
the correct values.

7. RESTORING THE DEFAULT CONFIGURATIONS OF THE CONVERTER
In order to restore the default configurations of the converter you must hold the reset key in the panel down for
five seconds. After that, all front LEDs will light up, indicating that the settings have been restored. After
releasing the key the converter will reboot with the factory default settings.
