1.
Determine which product software you need
According to versions of product, several firmwares can be loaded into FLASH memory upon delivery. But only one firmware can be run
at any one time, so it's very important to determine the relevant one.
- "SERVERCOM": COM Port emulation with RFC2217 extension, raw TCP socket application, Telnet compatible client
- "MODBUS»:
MODBUS TCP gateway
- "TCPCLIENT»:
TCP tunnel mode between two products, or on-request TCP calls to a server application
- "MULTIPOINT»: Multidrop UDP mode between any number of products, raw UDP socket application
- "DOWNLOAD": This is a specific firmware which enables product firmwares management: update, erase, add functions
Upon delivery, the enabled firmware is SERVERCOM.
2.
Determine the parameters of your application
•
Serial data format, baudrate,
•
Serial control signals driving source
•
...
3.
Collect network characteristics
You will need at hand some information about your LAN. The following is required:
•
Product IP address (see below)
•
LAN netmask (see below)
•
Gateway address (if required)
Product IP address: You must assign an IP address to the product (Except if you use DHCP, see below). You CANNOT JUST PICK
ONE AT RANDOM and wish it will work! The chosen address must meet the following requirements:
•
Its network part must match the network part of other devices on the same LAN,
•
Its host part must be different from any other devices on the same LAN (beware of printers, routers and gateways),
•
Its host part must not be a reserved value like 0 or 255.
NETMASKS: If no netmask applies, it can be deduced from the IP address: given IP address X.Y.Z.T, if X≤127, then the netmask is
255.0.0.0. If X≥128 and X≤191, then the netmask is 255.255.255.0. Otherwise the netmask is 255.255.255.0. If in doubt, please ask to
the local Network Administrator.
4.
Connect power supply
Plug the power supply using the Phoenix connector, as indicated on the back of the case. Notice that product has no ON/OFF switch, it
turns on automatically when powered.
5.
Access to administration mode via serial port
Push the switch towards the « Adm » position. The red (DIAG) light should blink twice per second. If it is not the case, try pushing the
switch in the opposite direction.
Connect the product to a PC serial port, using provided crossed cable.
This step allows product IP address setup. Below we describe how to do this with a PC with Windows
or operating systems (Linux...) can be used.
Run Hyperterminal
When asked to choose a modem or port, select a direct connection to COMx (COMx being the COM port on which you plugged the
product). Select the following default port parameters: 2400 bps, 8 bits, parity none, 1 stop bit, no flow control.
Hyperterminal now displays a blank window. Hit the « ENTER » key to display the admin prompt. ("root>")

IP address configuration
If you intend to use DHCP, please refer to documentation 'DTUS036 (COMETH-FIELD-RD user manual)'. The MAC address is written on
the label stuck on the product. Otherwise, you must now type the following commands to set up IP connectivity (you must type only the
text in bold characters, other text is issued by the product).
In the following lines, replace XXX.YYY.ZZZ.TTT by the IP address and netmask you choose for the product:
root> set net ip XXX.YYY.ZZZ.TTT
root> set net mask XXX.YYY.ZZZ.TTT
The following is required only if you will use a gateway:
root> set net gateway XXX.YYY.ZZZ.TTT
Before leaving configuration, save your modifications and apply:
root> save
root> reset
7.
Install the product in its final location
Now you can unplug the product from the administration PC and push the mode switch on the other side (thus allowing data to go
from Ethernet to the asynchronous interface).
Check the cabling of your device against the schematics of the product connector. Connect the product to the device, interposing a
crossover cable if necessary.
Plug the Ethernet jack from your HUB into the product. If the Ethernet cable is good and correctly inserted on both ends, the 10 Base T or
100 Base Tx light should go on on the product (and also on the HUB if it has a LINK led).
8.
Other configuration
To complete your product configuration, you can choose between these three different methods:
1. Using the serial port with Hyperterminal (refer to the user guide of the product and the firmware)
2. Telnet through the network (refer to the user guide of the product and the firmware)
3. Through Internet Explorer (discontinued method)
This method is not supported because the program "ComethAdministration" has been discontinued. Consequently, only old
releases of web browsers are supported.
a. Installation of the browser administration tool
You can download ComethAdministration.exe on our website:
install the software and create you a shortcut on your desktop.
b. Launch the browser administration software
Open the shortcut called ComethAdministration on your desktop.
c. Parameters configuration
To program the product parameters, it's necessary to have configured the login, password and IP address of your product by
the serial link and to have Internet Explorer.
Once the software is launched, an internet window is opened where you have to enter the login, password and IP address of the
product you wish to administrate.
All the parameters are configurable with this interface and you will be guided through each function with contextual help and
browser alerts.

VIP Windows COM port redirector software installation
This section applies only to Windows COM port based application.
Warning, the COM port redirector software works only if product executes SERVERCOM firmware. RFC 2217 mode should be activated
("set serial mode rfc2217").
Download the redirector software from ACKSYS website and read the "vip release notes.html" file. Run the installation wizard. This
installs the VIP software, allowing COM port redirection from MS Windows to the product.
Click on the shortcut on your desktop. Stop the service with the "setup" tab. Click on the "new" button in the "virtual port" tab. Select a free
com port in the list and set the IP address and TCP port of product (default values for the product are 192.168.1.253 and 2300). Save
your virtual port, and restart the service in the "setup" tab.
You are now ready to use the product through port redirection.
Just run your application and specify the COM port name that you selected in the previous step.
Please, check the following thoroughly before calling for support. If you must call, we will need complete information about your network
topology, IP addresses of intervening devices, description of your device's serial connector, model of the computer and operating system.
1.
Checking the hardware
Five LEDs allow hardware diagnostic.
Power:
this led lights up when the product is correctly powered.
If the POWER LED stays off, it means that your power supply is bad, or incorrectly connected.
Diag :
In Administration mode, this LED flashes twice per second, unevenly
In Exploitation mode, this LED flashes when an error is detected in characters received on the asynchronous interface
At Power up : if the product is programmed to use DHCP, this LED flashes once per second, until answer from a DHCP
server. In the opposite case, it stays lighten until the product is ready to use (in less than one second)
If the DIAG LED stays lighten at power up, it means that the product is out of order. Try to power it down, then up again after a
few seconds.
If the DIAG LED flashes to indicate Administration mode, push firmly the « Adm » switch in the opposite position (OFF).
10 Base T :
This LED is on if you use a 10 base T Ethernet link.
If the LED stays off, it means that your cable is bad, incorrectly inserted in the HUB or in the product.
This LED flashes when sending or receiving data of the LAN.
100 Base Tx :
This LED is on if you use a 100 base Tx Ethernet link.
TM
. Other devices (ANSI console...)
If the LED stays off, it means that your cable is bad, incorrectly inserted in the HUB or in the product.
This LED flashes when sending or receiving data of the LAN.
Serial Tx/Rx :
This LED flashes when sending or receiving data on the asynchronous serial interface.
If the Serial Tx/Rx LED stays off while your device is sending data, it means that the RS cable is bad, improperly connected, or
some kind of flow control forbids transmission.
If the Serial Tx/Rx LED stays off while you are sending data to your device, it means that some kind of flow control forbids
transmission, or the product does not receive Ethernet data frames.
If the serial Tx/Rx LED stay on while you are not sending data to your device and your device is not sending data, it means
that the RS cable is bad, improperly connected, A & B or A & B' are inverted, line polarization is required in RS422 multidrop

In RS485 or RS422 multidrop, line polarization is necessary for stability in idle state. Lack of polarization may prevent all
communication or generate of lot of errors. To activate polarization by the product, connect pin 1and 2, as well as pins 6
and 7 of the DSUB9 female connector.
The line-terminating resistor for RS422/RS485 lines reduces reflections created by long lines at high speed. It is not
required if the distance and the rate are within 1,000m at 9600bps, or 100m at 112kbps. To connect the terminating
resistor of the product, use the switch located on the side of the case.

TROUBLESHOOTING
Checking should be done in the following order.
2.
Checking the network topology
You must be sure that the IP address used by product is not used by another equipment on your network. In order to verify, you can
« ping » the product.
The default IP address of product is 192.168.1.253. In this case, power off the product and type:
C:\> arp -d 192.168.1.253
C:\> ping 192.168.1.253
According to the nature of the message, you can know if the address 192.168.1.253 is used on your network:
-
request timeout : this IP address is not used.
-
answer from 192.168.1.253 : this IP address is used by another equipment.
Be careful: If you have already changed the IP address of the product, ping that new one.
Power on the product. Now it should answer to PING, else check that the chosen IP address is compatible with the other addresses of
the LAN, and check the "gateway" parameter if the communication crosses a router.
If there is no answer, the IP address of the product is not this one. Correct the problem with the administration system. Be sure to save
the changed configuration and reset the product.
3.
Checking the configuration
When you can PING the product, you should be able to use remote administration. Try to connect to the administration system:
C:\> telnet 192.168.1.253
If the connection is refused, another TELNET is already connected to the product.
You can also use the asynchronous port administration. Please refer to the installation guide to do this.
Once in administration mode, check the serial parameters for proper settings. In the SERVERCOM firmware, the default TCP data port
number is 2300. If the mode is « rfc2217 », then DTR and RTS should be set to « driven » and incoming signals to « ignore », other serial
parameters are irrelevant.
4.
Checking the VIP COM port redirector (with SERVERCOM only)
In the VIP manager window, you should see the list of COM port name that you assigned in the installation. Select one of these. When
the port is in use, LEDs are displayed on the left of the IP address. You can check this by opening the port with Hyperterminal.
If the LEDs do not show up, the address or port given for the port is bad. Also, there may be a problem with the computer's network
parameters. In this case edit the port com properties and click on the "ping" button. If you have an answer, the network parameters are
correct. Check the virtual port parameter (TCP port) and that the firmware is "servercom".
