building LAN, or directly to the AcquiLite. Attach the laptop to the AcquiLite or LAN as shown in figure 6, Ethernet hookup. Step 2 - Attach the Laptop to the AcquiLite or to the LAN. The A7810 will automatically detect whether a direct or crossover cable is required, and will reverse polarity accordingly. This feature will allow you to use either a straight Ethernet cable or a crossover Ethernet cable interchangeably.
AcquiLite Administration Overview The AcquiLite should now be available on the local area network for you to access using a web browser such as Internet Explorer or Netscape. Step 1 - Use your web browser to connect to the AcquiLite by entering http://192.168.40.50/setup/ Where 192.168.40.50 is the IP address displayed on the on the AcquiLite LCD display.
Security The AcquiLite has three levels of security. These are “operator”, “user” and “admin”. When using a browser to access the AcquiLite, basic http authentication is used to prompt your browser for a username and password. The admin account uses “admin” as the default password. To change the password, select the Accounts menu from the left side tree display. Next, select the account name. Click the “Change Password” button to set a new password for the selected account.
Note: not all Modbus devices have built in driver support in the AcquiLite. If a device appears in the list with “Unknown” in the status column, you may need to upgrade the firmware on the AcquiLite to access the device. At the bottom of the device list page under the Type column, a link is shown that will show all the Modbus devices with built in driver support provided in the firmware. Use the System/Firmware update page to check for newer versions of the firmware. The Obvius.
Device Details. The device detail page will show a list of all the pulse input data points, alarm settings and console options. The data point names for most devices are automatically entered. At the top of the page, the status of the device is shown. This usually reports “ok” however it can include error information if the device is not responding properly. A list of device errors is available in the log file details section of this manual. At the bottom of the page, several buttons are present.
Device Configuration When the “configure” button is clicked from the device details page, the screen will be refreshed, with the same information, however the device name, alarm settings and console checkbox will be available. Device Name: This field allows you to specify a name for the device such as “main building power” or other useful name to indicate the location or function of the device. A name must be assigned to a device before the AcquiLite will log data for it.
Manual Device Add Options Modbus devices may be added manually by clicking on the “add” link on the bottom of the Modbus device list page. This option is intended for use when adding devices to the configuration profile prior to installing the physical hardware, or configuring Modbus/TCP devices that will not automatically populate in the Modbus device list. The manual setup page has several options that must be configured before the AcquiLite will recognize the Modbus device.
Troubleshooting Pulse inputs If the device you have attached does not appear in the Modbus device list, check the following: ● Verify the pulse input connections are correct . ● Verify the status LED blinks for the specific pulse input in question. Try bridging the two terminals at the input of the AcquiLite to verify the input LED turns on. ● Bridge the terminals of the pulse output meter and verify the input LED turns on. This will verify the wiring to the meter is correct.
SMTP Mail Server Address: The IP address of the email server on the LAN that will process and forward the email message to the recipient. Sender Address: The address that will be used in the “From:” line of the email. This is helpful in identifying the source of the alarm email message. If your SMTP mail server has junk filtering, you may be required to use a sender address that matches a mailbox address on the SMTP mail server; check with your mail server administrator for specific details on this issue.
this field blank. ● DNS 1, DNS2: These are the primary and secondary DNS servers. If you are using a dialout connection, these must be set to the DNS server provided by your dialup ISP. If you only use the AcquiLite on a crossover cable and/or dialin mode, you should leave these blank. ● DHCP (enable/disable) If you LAN has a DHCP server, you may enable this option and remove the previous options for IP, netmask, gateway, and DNS. Check with your LAN administrator first. ● HTTP Proxy.
Time Server: Specify the DNS name or IP address of your time server. The default “time.obvius.com” can be used if the AcquiLite has a connection to the Internet. The AcquiLite will attempt to synchronize time with the time server every upload session. This will ensure that the clock is checked and adjusted at a minimum of once per day. Typically, the synchronization will align the clock to within +-1 second of the internet time source or atomic clock.
Last Data Upload log: This log file contains a report from the last data upload attempt to remote database/webservers such as BMO. This log will show if any log files are being rejected by the dabase/webserver, or if the network is not allowing a connection. Last Modem Connection log: This log file shows the details of the modem operation including modem connection quality parameters. This is updated ever time the modem makes a dialin or dialout connection.

Modbus Status Data Upload Show Serial # Upload Data Now Modules Disable All (previous menu) Shutdown Reboot (previous menu) The TCP/IP sub menu will allow you to configure the Ethernet settings for the AcquiLite. To edit the IP settings, use the Menu button to change options, and press the Select button to edit the option. Once selected, you will see the current value displayed and a blinking square cursor on the first character. Press the Menu button to change the character or digit.
Erase log/config (previous menu) The Check Flash Disk option will force the AcquiLite to check the entire flash disk for file system integrity. This will require you to reboot the AcquiLite. The Enable Console feature will provide a shell prompt on the serial port for remote diagnostics. This is intended to be used by Obvius technical support only.
Date/Time: The date/time column reports the time at which data was logged from the Modbus device. Note: this is not necessarily the time at the start of the log cycle. Users with large number of devices may notice some of the Modbus devices at higher address numbers report 1 or 2 seconds after the first Modbus devices. This is because the 9600baud speed of the Modbus loop is not fast enough to log all Modbus devices in less than 1 second.
accept blank or NULL as a valid entry in a data table to represent invalid data. For data exported from the BMO website, the columns that are invalid (NULL) are reported as blank fields. This makes it easier to import into MS Excel as blank cells. With the current firmware, the AcquiLite will report blank fields rather than "NULL" to make direct import of data from the AcquiLite easier, as well as reduce the file size.
log file storage area is more than 75% full. ● Allow remote modbus device configuration: If enabled, users may remotely configure alarms and other modbus device features on the BMO website. When the AcquiLite uploads data to the BMO website, it will also download any new configuration information as needed. Note: if configuration changes are made to the AcquiLite, those changes will be uploaded to the BMO site.
Enertrax download direct from the AcquiLite Obvius provides a free tool called Enertrax DL that can automate the process of downloading log data from the AcquiLite to your Windows PC hard drive. Enertrax DL can merge new log data into existing log files on your computer as well as provide configuration information about the AcquiLite. Enertrax DL can also be configured to make LAN or Dialup calls to one or more AcquiLite or AcquiSuite data acquisition servers. Enertrax DL can be obtained from the obvius.
