Chapter 2. Getting started
The Güralp 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 Güralp 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 Güralp 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 Güralp 40TDE and the computer will acquire automatic IP addresses. You can then determine the IP address of the Güralp 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.
