Zonge GDP-32 II - User Manual

Networking the GDP
Start the NET utility.
Introduction
The easiest way to transfer files to or
from the GDP is over the network. The
GDP can either be connected directly to
a computer using a crossover cable, or
connected automatically to a LAN. The
network connection can be used to:
• Retrieve data files from the GDP.
• Transfer antenna cal files to the GDP.
• Install the latest operating programs
on the GDP.
• Place identical Time Schedules on
multiple GDPs.
When first powered up or after
a reset, the network will not be
loaded. At this point there are
three connection choices:
• Connect to Computer
using Manual Settings
• Connect to Network using
Automatic Settings
• Connect to Network using
Manual Settings
The symbols around the NET function key label indicate if the network is loaded or not.
If it is shown as +NET+, the network is currently loaded and ready for use. If it is shown
as -NET-, the network is not presently loaded and must be started.
Which type of connection are you using?
Directly to a computer– This type of connection is used mostly for transferring data files
to a laptop in the field. Requires manual settings on both the GDP and the computer.
To a Local Area Network– This type of connection is used in an office setting or a
connection to a router. Most often the network has a DHCP server so automatic settings
can be used. Otherwise, a valid IP address must be manually entered into the GDP.

The GDP-32 is a multi-function receiver designed for geophysical data acquisition, featuring a 24-bit system for high-resolution measurements. Its primary function is to collect and process geophysical data, with a strong emphasis on network connectivity for data transfer, system updates, and remote management.

Function Description:

The GDP-32 is engineered to facilitate the transfer of data files, antenna calibration files, and operating programs over a network. This network capability allows for efficient data retrieval from the GDP, transfer of necessary calibration files to the device, installation of the latest operating software, and the ability to apply identical time schedules to multiple GDP units. The device supports both direct connection to a computer using a crossover cable and integration into a Local Area Network (LAN).

The network interface is managed through a dedicated NET utility. The status of the network loading is indicated by symbols around the NET function key label: "+NET+" signifies that the network is loaded and ready for use, while "-NET-" indicates that the network is not currently loaded and needs to be initiated.

When initially powered up or after a reset, the network is not automatically loaded, offering three connection choices:

1. Connect to Computer using Manual Settings: This option is primarily used for direct data transfer to a laptop in the field. It requires manual IP settings on both the GDP and the connected computer.
2. Connect to Network using Automatic Settings: This is suitable for office environments or connections to a router, where a DHCP server typically assigns IP addresses automatically.
3. Connect to Network using Manual Settings: This option is used when connecting to a network without a DHCP server or when specific IP configurations are required.

Usage Features:

Direct Connection to a Computer:

For direct connections, the GDP is configured for manual IP settings. Recommended settings include an IP Address of 192.168.001.003 and a Subnet Mask of 255.255.255.000. When setting IP addresses for both the GDP and the computer, the first three octets (mmm.mmm.mmm) of the IP address must match, while the last octet (ddd) must be different. The Subnet Mask must be identical on both devices. After entering the correct settings, the "CONTINUE Enter" button is pressed to load the GDP network drivers. A crossover cable (Zonge PN: CROSS) is required for this type of connection.

To set up the computer for a direct connection, it needs to be configured with either completely manual IP settings or an Alternate Configuration. The Alternate Configuration is recommended as it stores the settings for future use. This involves accessing the "Network and Sharing Center" via the "Control Panel" (accessed through the START Button). Within the "Network and Sharing Center," "Change adapter settings" is selected, followed by double-clicking "Local Area Connection" and then "Properties." The "Internet Protocol Version 4 (TCP/IPv4)" properties are accessed, and the "Alternate Configuration" tab is selected. Here, "User configured" is chosen, and the IP address, Subnet mask, and Default gateway are set. A recommended IP address for the computer is 192.168.001.002, with a Subnet Mask of 255.255.255.0 and a Default Gateway of 192.168.001.254. This allows for multiple GDPs to be connected via a network switch, each with a unique last octet (e.g., .003, .004). After configuration, a two-minute timeout period is observed while Windows determines that it will not receive an automatic IP configuration and applies the Alternate Configuration.

Connecting to a Local Area Network (LAN):

When connecting the GDP to a LAN with a DHCP server, the GDP can automatically obtain its IP settings. This simplifies access from any computer on the network. The GDP is connected to a port on the network switch. From the initial network screen, the "SELECT DN End" button is pressed to choose "Automatic Settings," followed by "CONTINUE Enter" to activate the connection. If successful, the GDP will display its assigned IP address (e.g., 192.168.222.146) and Subnet Mask (255.255.255.0). This IP address can be used for ping testing, and the GDP name (e.g., \\GDP32SN328\C) is used for connecting via a mapped network drive.

Accessing GDP using an FTP Client:

For computers running Windows 10 or in networks that restrict mapped network drives, an FTP client like WinSCP can be used to access the GDP's flash disk. The FTP settings are:

• File protocol: FTP
• Encryption: No encryption
• Host Name: The IP Address of the GDP (e.g., 192.168.001.003)
• Port Number: 21
• Username: anonymous
• Password: none required (or left blank). If the FTP client has an "Anonymous login" checkbox, checking it will automatically configure the username and password. The FTP client can be configured to resemble Windows Explorer for drag-and-drop file transfers.

Mapping a Network Drive to the GDP:

To access the GDP's flash disk as a local drive, the "Map Network Drive" feature in Windows Explorer is used. Windows Explorer can be opened by holding the Windows key and pressing E. The "Map network drive" option is selected. A drive letter (e.g., Z:) is assigned, and the GDP's network path (e.g., \\gdp32sn87\c, replacing "87" with the GDP's serial number) is entered in the "Folder" field. The "Reconnect at logon" option should not be checked. After clicking "Finish," the GDP's C: drive is mapped to the assigned local drive letter, allowing access to its files and folders.

Troubleshooting Problems with Networking:

If a network connection cannot be established, several steps can be taken:

1. Verify Crossover Cable: Ensure a crossover cable is being used for direct computer-to-GDP connections.
2. Verify Cable Connection: Check the "Network and Sharing Center" or the network icon in the lower right of the screen to confirm that a cable is detected and that network activity lights are blinking.
3. Verify Computer IP Address:
   • Open the Command Prompt by typing "cmd" in the Windows search bar.
   • Type "ipconfig" and press Enter to view the computer's IP configuration.
   • Ensure the IP address, Subnet Mask, and Default Gateway are correct and compatible with the GDP's settings. For automatic IP addresses on a network, these numbers should be assigned by the DHCP server.
   • If the computer is on a network, the GDP's IP address must match the first three octets of the computer's IP address but have a different last octet.
4. Ping the GDP: In the Command Prompt, type "ping [GDP IP address]" (e.g., "ping 192.168.1.3") to check connectivity. A successful ping indicates that the GDP is reachable.
5. Check GDP IP Configuration:
   • From the GDP's main menu, press F8 (DOS).
   • Type "ipconfig" or "ipstat" to view the GDP's IP address, Subnet Mask, and Gateway.
   • Verify that these settings are correctly reported and compatible with the network. Note that pinging from the GDP to the computer may not work due to security settings.
6. Inspect Internal GDP Connection:
   • Lift the front panel of the GDP.
   • Check the LEDs on the front of the BD387 board. If the NET0 and NET1 lights are not active, it indicates a problem with the internal network connection within the GDP.

Maintenance Features:

The GDP's network capabilities inherently support maintenance by allowing for:

• Program Updates: The latest operating programs can be easily installed on the GDP via the network, ensuring the device runs with the most current software and features.
• Calibration File Transfers: Antenna calibration files and board calibration files can be transferred to the GDP, which is crucial for maintaining measurement accuracy.
• Data Management: Data caches, utility programs, and archived data (stored in the DATA folder) can be retrieved and managed through network access, facilitating data backup and analysis.
• Troubleshooting: The ability to check IP configurations on both the computer and the GDP, along with ping tests and visual inspection of internal network activity LEDs, provides essential tools for diagnosing and resolving connectivity issues.

The GDP program files, antenna calibration files, board calibration files, and un-archived data caches and utility programs are typically located on the root directory of the GDP drive, while archived data caches are stored in the dedicated DATA folder.
