content: Having first owned a TIC about twenty five years ago, I've not had one for about 10 years. Following buying a cheap but only partially working Thermovison 110 late last year, the bug has bitten. I just bought a ISG Talisman Wasp on ebay. It is ex airport fire service so not too beat-up and is complete with case and a couple of batteries. The price was right too, my offer was acceptedI'll post pictures when it arrives. It will be my first BST sensor camera. It will be nice to have standard video output too. It's probably NTSC but I can deal with that.

content: I have a number of Talisman Wasps in the garage so may be able to help with parts if needed. The battery is a standard ICOM handheld radio battery so easy to obtain or source a charger, if required. The batteries are also easily opened (screws used) in order to fit new cells.Fraser

content: Hi Fraser,Thanks for the reply. I'd spotted that the batteries appeared to be Icom units, but good to have confirmation. I had an IC2E handheld transceiver in the 1980'sThe unit comes with two batteries and a charger.I had seen your earlier thread on the Wasp and also information on the sensor engine on your website.

content: The Wasp arrived OKA quick check and all appears OK.Quick screen grab of me but from too close for proper focus.

content: Not bad.You may have a good number of dead pixels that have not been caught in the dead pixel map though. Not surprising considering the use these cameras see though. It could just be just noise ‘sparklies’ in your frame capture though.Fraser

content: I don't see any fixed bright or dark pixels, I think it is just noise. I need to look into the RS232 port next. I have some of the JST connectors, just need to find the right one. I know there is software out there.It came complete with the proper "peli" case, 3 good batteries ad the charge. Not bad for £200

content: I dug out a plug to fit the configuration connector, it's a 6 pin Hirose HR10A (not sure why I said JST before). I can't find any cnnection infornation though. When researching before buying the camera I was sure I saw a reference to the configuration software. I now beginning to doubt myself as I can't find anything.Does anyone have any information on using the the configuration connector on the ISG Talisman with BST engine?

content: If Talisman is anything like Argus 2, the 'BST control' RS232 is likely to be a separate entity to the 'camera control' RS232. I am not aware of any ISG 'camera' control software in public.The 'BST' one for the later Raytheon core (205D) is public. Which PCB you have will depend on the date of your camera.Does the BST control PCB have a multiturn pot on it and edge connector as Frasers' images ?If so that is the 'old' (200A) PCB, and while I am sure it probably also had RS232, that was only for Raytheon use, not customers.The 'new' 205D PCB has no pot and a connector at both ends with RS232 on it for the software that is 'out there'. I can look out the pinout later this week on an Argus camera.I'd suspect the 200A pinout was the same though, so may be worth trying.Bill
