CMG-40TDE
2 Getting started
The CMG-40TDE accelerometer is preconfigured for terminal access at
115,200 Baud from the DATA connector, to provide serial console
access at 38,400 Baud via the GPIO connector and to configure its
Ethernet interface (on the NET connector) using DHCP or APIPA.
The easiest way to configure the CMG-40TDE is via the web interface
so, if you have a DHCP server on your network, simply connect the
provided network lead to the NET connector and apply 12VDC power
via the supplied lead to the DATA connector. Allow the instrument
thirty seconds to boot and then check the log of the DHCP server to
ascertain the allocated IP address. You can then enter this into the
address bar of your web browser (using http or https) and immediately
access the status information and configuration interface.
Alternatively, you can connect the CMG-40TDE via a network switch
or network cross-over cable directly to a laptop or PC (some laptops
and PCs automatically configure their network ports so that a cross-
over cable is not required). If your operating system supports APIPA
(link-local addressing), both the CMG-40TDE and the computer will
acquire automatic IP addresses. You can then determine the IP
address of the CMG-40TDE by pinging the computer's broadcast
address.
If you have a network but cannot use DHCP or APIPA, you need to
manually configure an IP address using a serial connection. Connect
the provided network lead to the NET connector, 12VDC power via
the supplied lead to the DATA connector, and a serial port on your PC
to the GPIO connector. Start your terminal emulation software, such
as HyperTerm or Minicom (configured for 38,400 Baud), and then
follow the instructions in section 2.2.2 of the EAM manual to set a
temporary IP address. You can then enter this into the address bar of
your web browser (using HTTP or HTTPS) and immediately access the
status information and configuration interface. You should set a
permanent IP address at this point as the temporary address that you
have just set will not persist after a reboot. See section 6.1 of the EAM
manual for more details.
If you do not have a network, you can still access the configuration
interface using the serial console. Connect 12VDC power via the
supplied lead to the DATA connector and a serial port on your PC to
the GPIO connector. Start your terminal emulation software, such as
HyperTerm or Minicom (configured for 38,400 Baud), and then follow
the instructions in section 3.2 of the EAM manual.
