TCPIP TO RS232 CONVERTER CONFIGURATION The TCPIP to RS232 Converter is a device that allows serial based devices to be accessed via the Ethernet. In addition, it also allows Windows or DOS applications that are serial based to access devices on the Ethernet. Configuring the device is done through a Web Browser. Therefore, the device is shipped with a default set of configurations shown below: Default IP: Default Subnet Mask: Default Gateway:

192.168.0.190 255.255.255.0 192.168.0.250

If the default subnet mask matches your intranet’s subnet mask, and the default IP is not used by another device on your intranet, then simply connect the device to a hub or switch. Connect to the device through your Web Browser by entering: http://192.168.0.190/ How to determine if the IP address is available on your intranet: Using a DOS window, perform a ping operation to the default IP address: C:\ping 192.168.0.190 If the command times out, then it is ok to connect the device to your network. If the command returns within the time limit, then there is already something on the network with that IP address. If this is the case, then the Crossover Cable Method must be used. If the default subnet mask does not match your intranet, or if the IP address is already in use by another device on the network, then a Crossover Cable will be required to configure the device. Using a Crossover Cable to configure the device: Disconnect your intranet from you NIC card, and connect a Crossover Ethernet cable between your PC and the converter. Change the PCs Subnet Mask to 255.255.255.0, and restart the PC. To change the Subnet Mask, go to Control Panel and click on Network. Select the component that begins with TCP/IP and ends with the network controller on the PC. Click the properties button. Click on the IP Address Tab and the Subnet Mask can be changed from there. After the computer re-boots, you should be able to access the device through your web browser by entering: http://192.168.0.190/

The following screen shot shows the configuration page for the converter:

When configuration data has been changed the configuration pages will contain a new button called “Save Configuration”. See the screen shot below. The data that was changed for this to occur will not be saved in non-volatile memory until the Save Configuration button is clicked. If an invalid parameter was entered, and the save configuration button has not been pressed, then simply power cycle the device and it will return to the previously saved configuration. To return to the default factory configuration, hold down the pushbutton on the device while powering up. TCPIP to RS232 Converter Instructions.doc

Tip: You should at least change the units IP address. That way, new devices can be easily be configured by just connecting to the network

Establishing a connection with a Remote Converter: If your application software does not provide a means to access the device via TCPIP, then either a virtual com port will need to be installed, or a converter can be used to link your serial port to the Ethernet. To do this, you can configure the converter to connect to a Remote converter. In the Remote IP address and port, enter the Remote converter’s IP address and port. Once configured, the device will try to establish a connection with the Remote converter. Configuring Email: Below is a screen shot of the Email Configuration. Only SMTP email is available, thus you must determine your email server’s IP address. To determine your SMTP server’s IP address, ping the domain. Below is an example of pinging the mail server for ATT: Microsoft(R) Windows 98 (C)Copyright Microsoft Corp 1981-1999. C:\WINDOWS>ping mail.attbi.com Pinging mail.attbi.com [204.127.198.7] with 32 bytes of data: Reply from 204.127.198.7: bytes=32 time=89ms TTL=49 Reply from 204.127.198.7: bytes=32 time=89ms TTL=49 Reply from 204.127.198.7: bytes=32 time=90ms TTL=49 Reply from 204.127.198.7: bytes=32 time=88ms TTL=49 Ping statistics for 204.127.198.7: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 88ms, Maximum = 90ms, Average = 89ms C:\WINDOWS> In the above example, the IP address was 204.127.198.7. Configure Email Message In the Email On column the messages will be sent on whatever triggers you choose. In the Include In Email column the message will contain only the objects selected.
