Secure IO Relay does not open for XPass on Biostar

If you're using Secure Relays with Xpass and the relay doesn't open despite being defined correctly in Biostar as the Secure IO Relay (not the internal Xpass) then check your Firmware version.

FW 1.2.3 doesn't work and should be replaced with FW1.2.4 (attached)

I have already put the file on the 6 farms who have Biostar installed.

After defining your device go to the device properties and click Upgrade Firmware. You will be given a choice of 2 select the one for V1.2.4
