Notice of a Firmware Problem found in Handy Data Collector RTR-57U
[Information on the site of old english.tandd.com]
The following explains problems and solutions for our customers who are using our Handy Data Collector RTR-57U in conjunction with our Voltage Logger RVR-52 to record event data.
We sincerely apologize to our customers for any inconvenience or trouble this may have caused.
Affected Device
RTR-57U Main Unit Ver. 2.00 - 3.00
The problem occurs only when using RTR-57U and RVR-52 in Event Record Mode.
- It does not occur when using RVR-52 in either Voltage or Pulse Record Mode.
- Nor does it occur when using any of the other products in our RTR-5 Series.
Situation in which the Problem Occurs
We have found that when the RTR-57U uses wireless communication to gather current readings from an RVR-52 which has been set to record Event Data and a wireless communication error occurs, the appropriate error message does not appear, but instead the current reading will appear as “HI” and the event time data will be for the most recent one when communication was working properly.
- If a communication error does not occur, this problem will not occur either.
- Also note that this problem in no way effects the recorded data in the RVR-52 itself.
Procedure for Gathering Current Readings
In the RTR-57U Main Menu, select [WL Gather Data] - Select the Remote(s) - [WL Remote Info].
In the RTR-57U Main Menu, select [WL Gather Data] - Select the Remote(s) - [WL Remote Info].
Example of Normal Display
The most recent recorded Event (edge info) is displayed.
When a communication error occurs, the display will appear as follows:
Problem Display
When a communication error occurs, even if the current reading should be [LOW], it will appear as [HI].
If wireless communication returns to normal, the display will also return to normal making it difficult to judge whether or not a problem has occurred, but if it has and the battery is removed from the Remote Unit the display will remain as above.
Checking the Version of your RTR-57U
When the power is turned on, the info for the main unit is shown for about 0.5 seconds. If the version is 2.00 - 3.00 the firmware needs to be repaired.
Units released after the firmware has been updated will be Ver 3.20 or higher.
Questions and Inquiries
For answers to any questions you may have about repair, please contact the agent from which you purchased the unit.
