Q: Why I experience a “Database connection failed” or “Server connection failed” error when I launch BTS Client to perform a test.

A: If the MySQL or BTSServer is not at a status of started, you will experience such error prompt when you launch BTS client connected with it. Go System Services by services.msc in the run or manage on the right click menu of the computer, find “MySQL” and “BTSServer” then start them. If system cannot start one or all of them, you may need to reinstall the BTSServer.


Q: How many channels could one BTSServer hosts? And what is the guidance?

A: Based on the data executing and transferring efficiency, 2000 records per second can be securely and effectively handled by BTSServer. That is to say 2000 channels could be hosted when you record data every second (or 1Hz) and 200 channels at every 0.1second (or 10Hz). Since auxiliary channels have less       information, 4 such channels could be counted as one.


Q: Why there is no available devices listed for operation.

A: If you can see the IP address of the equipment from the Device List on the left column of the BTSClient, you may consider: a). The BTS connected has a different Server_IP from the IP address of the host computer. Change one of them will fix this problem. b), the BTSClient is not compatible with the BTS type connected. Update the BTSClient to a newer one. If you cannot see any IP addresses, you should consider the hardware connection.


Q: I have many channels of the same model under different devices. I have to do the same job for the devices but to launch a same test. Is there any way to simplify this action?

A: You can map at most 256 (8 rows* 32 columns) channel for one virtual channel. Right click on the BTSV to set virtual device. You can map channels under different devices to one virtual device.


Q: If my settings for the safety protection and jump condition are the same, which one has the priority?

A: The safety protection functions prior to jump conditions. If you set a lower voltage limit of 2.7V, and discharge to 2.7V to jump to next step, the channel will get protected when the battery’s voltage reaches 2.7V.


Q: Why I can only see the last period of the data.

A: BTSDA has a default data loading behavior – loading the last 20 cycles of the data. You can drag the yellow bar below to other cycle ranges, or right click on it to select the loading range, or right click on the data area to set default loading behavior under cycle layer settings.


Q: What does the - V stand for and its application?

A: For NiMH battery, there will be a voltage drop when battery gets fully charged. This drop rates you can specify as a cut-off condition for the charge step. - V is enabled only for CC charge step.
