content: Hi friends.Anyone have control software (GUI or command list) for Raytheon BST and ASi cores?Also, does the analog BST (300A) cameras support serial communication?Thanks!

content: BST core control software was found and posted on the forum.I have put a copy on my websitehttp://www.fire-tics.co.uk/project3/index.htmASI 'customer' did very little, just a start screen I think. I do not think the ASi 'factory' ever got out.Bill

content: Thanks Bill.But I think your link is for digital (300D) BST only, what about analog versions?Also I've seen some feature-rich controller for ASi screen shots here:https://www.eevblog.com/forum/thermal-imaging/raytheon-l-3-thermal-eye-x-series-repair-new-patient-for-fraser-x50/Is that considered as "controlled release" or something?

content: I am not aware of anything for the 'analog' BST cores. I do not recall any control being advertised on the main 80-way but would need to check further - and cannot at present.I think calibration access was via the PCB finger edge connector.The GUI you have found is for later ASi series, 3500/3600/4500. My comment referred to the earlier 2000AS coreBill

content: Hi Bill.Just another question... Can we increase the gain on analog BST cores? I remember read in the forum that there's a "pot" to adjust, how can I do it?Thanks.

content: Yes, analogue BST has voltage controlled gain and offset. the same method was provided on 'digital' BST cores as a backward compatibility.It is explained from an Argus3 viewpoint in the posts from here:https://www.eevblog.com/forum/thermal-imaging/argus-3-(bst)-teardown-and-repairs/msg3556147/#msg3556147So far I have not done the Argus2 version which would show how the manual controls are connected to the 80 way connector.

content: Quote from: Bill W on May 26, 2023, 10:15:34 amHowever I have some of the files ready, so this should help.It is the circuit on the Argus2 detector PCB (itself a part clone of the Raytheon one) showing the interfaces to the BST 80 way connector.The links are to choose between using external analog, direct pot and automatic for the gain/level control. Note the BST supplies '+5VCONT' for use on the controls.

content: Quote from: Logan on May 26, 2023, 12:13:08 pmCorrect - for the analogue BST.ENOS, ENGN enable the 'external' / manual control of offset and gain.The links on ENDC and GNDC are Argus functions between real pots and a digital potentiometer IC controlled by the Argus micro (off sheet)The DC inputs were simply a way to get a gain and offset vlaue of 0 - 255 in the core.0V (0) is zero gain - grey screen0V (0) is zero offset (black) and 5V (255) is full offset (white)[I think - might be the other way round]The digital BST also had a further multiplier factor you could change with the software

content: Clear explanation.Thanks a lot Bill!
