Dear Suprema Patners & Customers,
If you are going to add 2nd generation device to BioStar 1.93 SW, please consider two parts.
1) FW compatibility
BioStar 1.93 doesn't support the most recent version of 2nd generation device. And, you can't add the devices to BioStar 1.93 with an error message.
BEW2 : 1.3.0-20181115
BS2 : 1.7.0_20181126 or higher version
BSA2 : 1.6.0_20190104
BSL2 : 1.4.0-20181106
Those FW can be not connected to BioStar 1.93.
Fail to read parameter from Device
2) Downgrade Issue
If you receive recently BioStation A2 product and you want to downgrade the version of A2, you can't downgrade the device successfully because of the sensor(OP6) compatibility.
To distinguish the sensor type, you can prevent the issue if you confirm the serial number below.
Please do not downgrade for the below list. The downgraded device will be malfunction and you should proceed it as RMA.
A2-OEPW : 939342346 ~
A2-OMPW : 939263914 ~
A2-OHPW : 939431431 ~
A2-OIPW : Not produced with OP6 yet. The schedule is not fixed.
BioStation 2 & BioEntry W2
You can downgrade W2 and BS2 without a HW problem, but please be aware that we can't ensure the compatibility between BioStar 1.93 and recent firmware except the below information.
BEW2 : 1.1.5 - 20171026
BS2 : 1.5.0 - 20170927
BSA2 : 1.4.0 - 20170927
BSL2 : 1.2.4 - 20170830
In conclusion, we highly recommend to use BioStar2 SW if you have 2nd generation device.
To support the DB migration from BioStar 1 to BioStar 2, we are going to release a DB converter tool.
