      How do you Test and Verify Accutech Communications?


      How do you test and verify RF communications between an Accutech field unit and a base radio?


      The RF Channel and RF Baud rate need to match on both the field unit and the base radio.  Let untouched, the display on the base radio will indicate the number of field units reporting back to the base radio ("3 WI"  = 3 Wireless Instruments). But how does one determine the robustness or reliabiliry of the RF signal coming through?

      There are two different tests available that can be performed from the field unit:
      1 - RSSI - Received Signal Strength Indicator, measures the RF signal intensity as seen at the field unit
      2 - LNK TST - Link test that looks at the transmission success rate

      1 - RSSI

      For firmware 2.03.1 and older, the RSSI Diagnostic, located in the field unit’s diagnostic menu, displays the RF signal strength in one of seven ranges. The signal strength is displayed on the LCD using a combination of ‘>’ and ‘’ characters. Full signal strength is displayed as “> > > > > > >”, while minimum signal strength is displayed as “> _ _ _ _ _ _”. If the field unit is not communicating with the base radio (i.e., NO RF), all underscore symbols will be displayed (“ _ _ _ _ _ _”).

      The RSSI is measured every time the field unit receives a message from the base radio. The signal strength of the received message from the base radio is calculated during this time. The actual signal strength in dBm for each range is shown below:

      To place the field unit in RSSI Diagnostic mode, start from the DIAGNSE menu, navigate to RSSI and press ENTER.

      Now that the field unit is in the RSSI mode, you might try to move the field unit about to see what sort of reception it has, listerning for the abse radio. Look at the LCD panel; the ‘>’ might fluctuate. One should estimate an average value based on these fluctuations. The ideal signal integrity is seven arrows.

      If you see a NO RF message, then satisfactory RF communication is not being made with the base radio. If your application allows, move the field unit to a different position and check again for communications. If your application only allows you to mount at this particular point, you may want to try a slower baud rate setting for an increased range or consider improving the RF path (raising or repositioning the base radio antenna, clearing obstructions from the path, using external antenna at the field unit, etc... )

      2 - LNK TST

      The Link Test command is located in the field unit’s DIAGNSE menu. Using the <NEXT> and <ENTER> buttons, navigate to link test and press the <ENTER> button to begin the test. The field unit will begin to test the link in both directions (to and from the base radio). During this time, the word TEST will move back and forth across the LCD panel. When the test ends, the field unit displays the quality of the link. Be aware that the field unit uses the configured baud and transmission rates to perform this test. The length of time it takes to perform this test depends on the device’s normal transmitting rate.

      The Link Test can be performed from the field unit, the base radio or through Accutech Manager. To place the field unit in Link Test mode, follow the menu map shown below. The Link Test menu is under the DIAGNSE menu and not the CONFIG menu.

      When enough messages have been observed by the field unit, the link strength will be shown on the LCD display. A display of 5 STARR indicates the strongest link, while a display of 1 STARR indicates the weakest link. The link test will continue to be evaluated and the rating on the screen may self adjust. Keep in mind that the longer the link test runs, the more data the Field Unit needs to evaluate.

      The Link Test reports the percentage of successful messages received from the field unit being tested.

      STARR % Success
      5 90-100%
      4 80-89%
      3 60-79%
      2 40-59%
      1 0-39%

      When performing the field unit installation procedure, be sure to place the field unit in a location where it receives the highest signal strength number possible. A stronger link means fewer data re-transmits and a longer battery life.

      ION73xx Firmware Upgrade Recovery

      Release Notice


      This KB article describes a new feature added to ION Setup V2.2 in Build 716 which allows a user to recover a failed firmware upgrade on any ION73xx family product.

      When an ION73xx meter firmware upgrade gets interrupted by a loss of communications, power loss or any other means there is still a way to recover from its failed state. Previously, using ION Setup, users could go through a manually process to recover the firmware upgrade. The changes made to ION Setup in V2.2, build 716, detects if the device is in a failed upgrade state and prompts the user to recover the firmware upgrade.

      It is important to note that if you experience a failed upgrade on an ION73xx series meter, any settings or changes made to the template of your device will not be retained. These settings include PT/CT settings, Clock Settings, Nameplate Settings, Energy Readings and ITC Settings. This is because during upgrade, the settings of the template are temporarily backed up to the computer via ION Setup. When the connection is lost and ION Setup is restarted those settings are not retained. In this case a saved copy of the template being used will be required. If you do not have a saved copy of your particular template, you can manually restore appropriate settings using the factory supplied template.

      Goals and Symptoms

      ION Setup v2.2 build 716

      Causes and Fixes

      One known cause of this problem is the loss of main power to the meter during a firmware upgrade.

      1) How to tell if your upgrade has failed
      During normal operation the meter will display the text Upgrading… on the LCD screen.  Also the communication LED (L2) will be toggling as communication traffic goes back and forth from the computer or server to the meter.

      Additionally, the Firmware Upgrade dialog box in ION Setup will show status updates every 10% during the firmware upgrade process.
      If there are any troubles with communications between the meter and the computer ION setup will show entries in the Firmware Upgrade dialog box that look like the ones shown below.

      In this case the RS-485 cable that was connected to the meter was disconnected to simulate a loss of communications.  These messages are just signs that communications have been lost for one reason or another.  In this case the user should not assume that their meter is broken.  If the user finds that these messages continue then they may choose to Abort the upgrade and restart.  However they should first be sure that the communication line between the computer and the meter is properly connected before aborting the upgrade.

        • Note:  If a user chooses to restart their firmware upgrade it is not necessary and not recommended to power cycle their meter before restarting the upgrade.

      In this example the RS-485 connection was re-connected after two No Response entries into the Firmware Upgrade dialog box.  As seen below the upgrade process continued once the connection was re-established.

      If communications do not resume ION Setup will try to re-establish communications a number of times.  If there is no response after those tries ION Setup will consider the upgrade a failure and end the process.  The log below displays what this situation would look like.
      Excerpt from the ION Setup Upgrade.log file:



      This is the beginning of the firmware upgrade process.  ION Setup records the date, meter type, Serial Number, Unit ID and baud rate.
      Also each step in the process is documented here.

      After a number of tries ION Setup will end the upgrade process. You will see the following screen once an upgrade has failed.
      Exit this screen and you will be advised that communication has been lost, as seen below.
      Press OK and you will be prompted again as seen below.
      Completely exit ION Setup and proceed to the next step to recover your firmware upgrade.

      2 )  How to restart the upgrade process.
      Open ION Setup. With this new feature added to ION Setup, resuming your firmware upgrade is as simple as restarting ION Setup in Single ION device configuration mode. Make sure to select the check box to use Single ION device configuration mode, as shown below.

      Upon startup in single meter mode, you will be prompted to choose a connection type. Select the appropriate connection type, enter the appropriate information (port, phone number or IP), and press OK to connect to the desired device.


      This is the point at which ION Setup will recognize if your ION 73xx family meter is currently in upgrade mode. You will be prompted as seen below. Select Yes to recover your firmware upgrade.

      At this point you will be prompted to select an ION Firmware Upgrade file (*.UPG), as shown below. Select the firmware file required for the upgrade. Press Open.



      ION Setup will now resume your upgrade as shown below.



      Once the upgrade is completed the following prompt will appear.



      Press Exit and you will be returned to the Select Connection Type screen, shown below. At this stage in the process you will be prompted to upload the appropriate template to the device.


      Again, select the appropriate connection type, enter the appropriate information (port, phone number or IP), and press OK to connect to the device. You will now be brought to the Setup Assistant screen. Click on the Template settings found in the left pane. Now click the Send to Meter tab shown below. This will allow you to select and upload the appropriate template to the meter. Click the Send button shown below.


      You will now be prompted by the following window.



      Click OK and you will be prompted to select the ION Setup Device Configuration File (Template). Select the template you wish to apply to the meter and press Open.



      You will now be prompted by the Template Paste Options window. As explained at the top of this article, when a failed firmware upgrade occurs, custom settings saved to your template are not retained. As a consequence the template paste options screen has no effect. The check boxes shown in the graphic below can be left checked or not as they have no effect. Again, the settings and data below (PT/CT settings, Clock Settings, Nameplate Settings, Energy Readings, ITC Settings), will not be retained and must be manually restored.



      Once you have pressed OK on the window above, you will see the following status window appear indicating the template is being uploaded to the device. Allow the process to complete.




      Upon completion the window below will appear indicating the template was successfully applied to the device.



      Press OK and you will be returned to the Setup Assistant window. One last step remains. It is recommended to once again, completely exit ION Setup and reconnect to the device. This is to ensure that ION Setup returns to normal operating mode instead of Firmware Recovery Mode. The upgrade recovery of your ION73xx family device is now complete.
