In Figure 10 it can be seen where the RME1-TC analog terminals are placed. The inputs are in
columns on both sides of the device
The inputs start numbering from 0. So that the first channel is CH0.The same way, each terminal
is numbered for its function and the channel it belongs to. So, the RME1-TC first terminal in
Channel 0 is called (PTO-), meaning: negative terminal of the thermocouple.

Configuration
3.1 Basic ethernet configuration
The first step to be taken is the network parameters configuration by any of the following
methods:
a) DHCP (AUTOMATIC CONFIGURATION)
b) Exemys Device Locator (Best recommended method)
c) Serial Port
d) ARP Method
a) IP address configuration with DHCP
The RME1-TC default configuration is IP 0.0.0.0, so when turned on, it will search a DHCP server.
RME1-TC tries to negotiate an IP address with the DHCP server for a maximum period of 10
seconds. If the DHCP fails to answer in that period, the RME1-TC will show an error code by
means of its indicator LEDs (See Table 4) and will try to establish connection with the DHCP
server 60 seconds later. This process will be repeated indefinitely until a DHCP server assigns an
IP address to RME1-TC or until the user assigns a static IP address.
a) IP address configuration with Exemys Device Locator (EDL)
The Exemys Device Locator Application Program is intended to be used for the basic
configuration of any Exemys device over your ethernet network. It allows searching, identifying
and configuring the basic network parameters.
This simple application program is distributed with any Exemys product in the accompanying CD.
You can also download the latest version of this program from the Exemys Web Site
(www.exemys.com).
The Device Locator application must be run from any PC within the network where the Exemys
devices to be configured are installed.
www.exemys.com Rev. 1 Page 15

RME1-TC User’s Manual - Thermocouple Acquisition Module Exemys
Figure 13 - Exemys device locator
• DEVICE: Name of the device, such as RME1-TC or SSE232-ST
• MAC ADDRESS: Hardware Ethernet Address of the device.
• VERSION: Firmware version running in that device
• PASSWORD
• HOST: Name of the equipment of NBNS identification
• DHCP: If the CheckBox is activated, the device net parameters will be obtained from a
DHCP server.
• IP: IP address configured in the device.
• NETMASK: Subnet mask configured in the device
• GATEWAY: Output from a net to others.
IMPORTANT:
It is not necessary for the device to be properly configured. If the device is correctly connected
and working, it will be found by the Device Locator Application Program.
To refresh the grid, click on the “Query Network” button. This action will make the device
Locator search any Exemys device in the network again.
You can change any of these basic network parameters within the Device Locator program.
To configure any Exemys device found by the Device Locator:
• Select the device in the grid and click on the “Properties” button, or open the “Actions”
menu and select the “Properties” command. You will see the Properties dialog box.
• All Exemys devices provide a Remote Configuration Password. This password is used by
the Web configuration page and remote command Console in the device.
www.exemys.com Rev. 1 Page 16

RME1-TC User’s Manual - Thermocouple Acquisition Module Exemys
• If the device has a configured password, enter the password in the Device Password box.
The manufacturer’s box has a blank.
• You can type an IP address,
Netmask and Gateway IP Address
or you can click on the “Use
DHCP” check box to make the
device search a DHCP Server. The
RME1-TC has been manufactured
with the DHCP feature activated.
• You can give the device a personal
name within the field “Host
Name” or you can leave the one
predetermined when
manufactured.
• Click on the OK button for the
Device Locator send this
information to the device.
• If the password is not correct, you
will see the message “Error when
changing the configuration”.
Check the equipment to be
configured password. The device will not answer any message sent by the Device Locator
during the first five seconds after an incorrect password. This is to avoid any brute force
method to change the network parameters of the device.
Fi
g
ure 14 - Device locator
• If the device does not respond, the Device Locator will show a “No Response from
Device” message. Make sure the device is turned on and connected to the ethernet
network.
• The Exemys device will reset so the changes in the configuration take effect.
• If no change is necessary, click on the “Close” button to close the Properties dialog box.
• After a few seconds the device being reset will answer again to the requests of the
Device Locator software. Click on the “Query network” button to refresh the grid and
make sure the parameters were changed.
c) IP address configuration with serial port
Connecting the serial port of the PC to the serial port of the device , as it was shown in Picture 7,
you can use an utilitarian software such as the Hyperterminal (Microsoft Windows®) to be
connected with the equipment and modify all its parameters . Once the port is opened with the
serial 9600,8,N,1 parameters configuration, the RME1-TC must turn on and type ”cfg” with the
Hyperterminal before 7 seconds have elapsed from the moment it is turned on. You will get
access of the configuration through serial port and will see :
www.exemys.com Rev. 1 Page 17

RME1-TC User’s Manual - Thermocouple Acquisition Module Exemys
RME1-TC – Exemys:
----------------
It is important to mention that this way not only the net parameters can be modified but also all
the equipment parameters can be reached. For further information consult Appendix D.
d) IP address configuration with ARP method
If the RME1-TC receives ICMP packets after being turned on, it will take the destination IP of
these packets and this will start being the device IP address. For further information see
appendix E.
3.2 Device parameters configuration
Configuration parameters can be modified by three different ways:
- Web page configuration
- Telnet console configuration (See Appendix D)
- Serial console configuration (See Appendix D)
Once the RME1-TC has a valid IP address you may access the web page to configure the rest of
the parameters.
1. If your web navigator is configured to search for a Proxy server, disable that option.
2. If you have the Exemys Device Locator software, select the device and press the button
“Configure”.
3. Type the RME1-TC IP address field of your navigator.
Figure 15 - Enter the IP address in the Web browser.
4. In your web browser you will see the inputs value and a link to configure the device.
5. If you click on the link the RME1-TC will ask for the password to enter the page. Type
“admin” as user name and then the password to enter. The RME1-TC defaults have no
password, so that the device will not ask for it unless the user enables it.
www.exemys.com Rev. 1 Page 18

RME1-TC User’s Manual - Thermocouple Acquisition Module Exemys
Figure 16 - Enter the Host name in the Web browser
As it is shown in the figure above, the name of the analog module in the manufacturer’s
configuration is NBNS: RME1-TC (last digits from Mac address) , and this name can be changed
using the Exemys Device Locator by means of the Host name parameter, in properties.
For example, if the Mac address of the device is 00:OB:FA:30:10:4B, The name in the
manufacturer’s configuration will be RME1-TC- 30104B
There is no need for the device to be correctly configured. If the device is connected and works
well, you will be able to get access by means of a web browser using NBNS as its name
NOTE:
In several sections of the web interface, the RME1-TC has a help symbol “?” . If you click on it,
you will get a help window for the configuration section you are.
3.2.1 Network configuration
Network parameters can be configured by all the methods already mentioned but t can be done
through the WEB interface too.
It is important to make it clear that the name of the device is useful for two tasks. One of them
is to identify each device in the Exemys Device Locator, when a searching is in progress. The
other is to use the name of the device instead of its IP address (NBNS protocol)
The NBNS ( NetBios Name Server) allows the user, in case of ignoring or simply not remembering
the module IP address, search it literally through the name in the LAN net from a web browser.
