It’s probably a fair bet you’ve found this page whilst searching for the programming software for either the DP770 portable radio, TM840 mobile radio or the TR850 repeater from Kirisun.
The programming software for these models is the Kirisun CPSp. And the latest version (at time of writing) is v1.91.
You will also need some programming cables…
Kirisun cables are hard to find in the UK. This information is for reference as we cannot supply these cables. The Kirisun DP770 requires the Kirisun KSPL-15 programming cable (if you can find one). The TM840 / TM880 mobile radios require a Kirisun KSPL-U21 programing cable (again, if you can find one). The TR-850 repeater requires a Kirisun KSPL-17 programming cable. The only place we managed to find one was on AliExpress.
Unfortunately, we have not been able to find an alternative cables. It appears only genuine Kirisun cables work. If you’ve found otherwise, please let us know in the comments section.
