I'm not sure which version of Escribe you are running so I'll post the one you need. This is the latest one - it works on all the Evolv DNA chips. They also have a SP4 service pack available (it's an add on) for the 250. No worries though because my Triade 250 already came with 1.2 SP4 so I didn't need to update it.
[RECOMMENDED]
*** 2016-08-08 EScribe 1.2 SP3 ***
https://downloads.evolvapor.com/SetupES250.exe (57MB standardalone installer)
This version improves a lot of the basics of EScribe. Here is a list of improvements, by no means complete:
- Most windows are no longer modal.
- In Options, User Interface allows you to choose a desired complexity.
- This version is more modular. Device Monitor, Calculator, Production Utility, and Serial Terminal are now all optional install and can run separately.
- Other changes.
Device Monitor has been improved as well:
- You do not have to start EScribe to launch Device Monitor. It can be launched independently from the Start menu.
- You can run multiple copies of Device Monitor, and uploading/downloading settings will pause it.
- You can scroll back in time.
This version can communicate with DNA 60, 60 Small Screen, 75, 200, and 250.
Here is the SP4 update/add on. You still need the above ^^^, this just adds to it.
[EARLY]
*** EScribe 1.2 SP4 ***
https://downloads.evolvapor.com/SetupES_1_2_SP4_ServicePack.exe (11MB service pack)
This service pack is mostly bug fixes.
On the EScribe side:
- This resolves some scaling issues in Large Fonts mode / on high-DPI screens.
- Get Information shows which tests were actually performed by the manufacturer in Production Utility.
- Get Information's Manufacturer link did not work in 1.2 SP3. This has been fixed.
- When you had more than one DNA device connected, the auto-connect did not automatically select the new one in the Connect dialog. This has been fixed.
- Minor compatibility and bug fixes.
On the device side:
- Fixed a bug on the DNA 250 that could cause its charging to be slow with certain USB cables (in my tests, the problem cables were flat).
Other:
- For DNA 250, Production Utility now requires charge tests to be at least 900 mA. This may require a powered USB hub.
