Configuring Ethernet Bridge
The Ethernet/RS-232 Interface card has an Ethernet Bridge that converts
the ethernet packets to serial data signals for processing by the embedded
microcontroller. The Ethernet Bridge must be properly configured for
serial communications with the microcontroller. For example, settings on
the Bridge, such as Baud Rate and Flow Control, must match the jumper
settings on the interface board.
There are two ways to gain access to the configuration menu for the
Ethernet Bridge. One is to run the Setup program that is available on the
Software CD. This program will find your instrument and allow you to
configure it by clicking on the instrument’s IP address. You will then need
to enter the correct username and password to be able to configure the
device.
Default Username: root
Default Password: dbps
The other method is to open up a web browser like Internet Explorer, and
type in the IP address for the instrument. Again, you will be asked for the
username and password. Once you have accessed the configuration page,
follow these steps for proper setup.
1. Click Configuration > Serial Port, and ensure that the following
settings have been selected:
• Baud Rate: 9600
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None
Click Apply once you have finished adjusting the above settings.
2. Now click Configuration > Network. If your network uses a DHCP
server (ask your IT department) you should select Obtain IP address
automatically using DHCP and then click Apply. If your network
doesn’t use a DHCP server, select Use the following IP address: and
enter an appropriate IP address, Subnet Mask and Default Gateway. .
3. Ask for assistance from your IT department to obtain an appropriate
IP address, Subnet Mask, Default Gateway, Name Server, and
Domain. Once you have made the appropriate changes, click Apply. If
this changed the setting, the device will reboot, so you will have to
renew your connection to its configuration webpage for any further
configuration changes.
