content: It appears to be the same as mine (but with the Hitachi branding) Checkout the LA3200 datasheet/manual for reference to the PODS.This I believe is the high-speed POD type, which doesn't have as many inputs as the standard PODs etc but it's still better than no POD.http://www.ebay.co.uk/itm/GLOBAL-SPECIALTIES-AP-03-HIGH-SPEED-DATA-POD-NEW-/150891381400?pt=LH_DefaultDomain_0&hash=item2321d3c298(Please insert your carma charging cable into the socket provided, always check correct polarity before charging!)_____| o o |--------

content: hi i also have one of these logic analyzers and have been looking for the pinout or schematic so i could make my own pods just wondering if you found any information out about the pins yet. I have contacted TTi but have not heard back yet ill keep you up to date when i do any help would be great.thanksJason

content: QuoteThis gear is so old (15+ years) that it's unfair to complain too much about lack of info, especially where it does not exist in an easily distributable digital form.Offering to scan some schematics is pretty generous, and it should allow pods to be reconstructed, keeping it useful - at least the company is still around and hasn't changed hands umpteen times over the years, which is a common cause of loss of information.

content: I received an email back today saying that PDF and scans are not available but a hard copy of the service manual is for 80 US . I dont think I am going to cough up the 80 bucks for a 25 dollar logic analyzer. I can't believe it would be that hard for a company to scan those documents and post them online. There has to be someone answering the phones or filing that could do it.As for contacting Hitachi Denshi no luck I have tried several times and have never heard back from them but I am not so sure my emails are making to the right person.Any info pics schematic ect. would be great if anyone comes up with any.Thanks Jason

content: Hi, here are some pics of my AP-01 Pod.http://www.tinypixels.co.uk/test_equip/la3200/la3200_pod_01.JPGhttp://www.tinypixels.co.uk/test_equip/la3200/la3200_pod_02.JPGhttp://www.tinypixels.co.uk/test_equip/la3200/la3200_pod_03.JPGhttp://www.tinypixels.co.uk/test_equip/la3200/la3200_pod_04.JPGhttp://www.tinypixels.co.uk/test_equip/la3200/la3200_pod_05.JPGThe only home build POD info I could find was one for the earlier LA160 model.http://sonicsheep.com/Electronics/3-LA160%20Writeup.htmIt would certainly be nice to create a modern SMD version of the AP-01 POD.Please post if you get any PDF documents; It would certainly go a long way to keep these going for a few more years at least.RegardsJules

content: Erik,I have attached a file PI_FOO2452.pdf showing the AP03V pcb image which I have designed from original TTI circuits. This will work with the Thurlby Instruments LA3200, LA4800 and TA320 analysers, Global Specialties GA 320S Logic Analyzer and the Hitachi equivalents ( VC-3120).The circuit came from the service manual athttp://w.ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/Thurlby_TTiscroll down to Thurlby Thandar LA3200 service manual.This pcb can be a 16 channel AP01 logic pod or an AP03 , an AP04 or AP03V , AP04V depending on how you populate it. Of course an AP02 would be three of the 16 channel AP01's.It was designed using the free version of Eagle PCB so is a small double sided smt 100 by 80 mm board fabricated in Belgium through Farnell.I have also designed a pcb for a full 32 channel AP01 pod which is the same size and also double sided smt but far less complicated as it is TTL fixed threshold. The AP01 pcb image is attached as PI_FOO2491.pdfAnyone experienced enough to help test an AP03V ?Rob

content: Hi to all LA3200/4800 usersMy first post here following recent work on the LA4800 and AP02 pod I won on eBay earlier this year:- Software: LA MAIN v3.20; LA 4800 v3.20- Original 2.4V/100mAh NiCd battery on CPU board had leaked and measured 0.16V; replaced with Varta 2.4V/150mAh NiMH (same form-factor) obtained via eBay- R12 changed from 1k to 560R to adjust trickle/standby charging current to 4.something mA as per new battery spec- Puzzling double-sided sticky pad (with one side still protected) removed from underside of CPU board beneath battery- Socketed ICs on CPU board removed while cleaning board (flux remover, soapy water, rinse) - which seems to have fixed an intermittent power-up problem when one-in-ten times the screen came up garbage and there were no beeps- One rear panel foot missing - replaced all with set from my cannibalised Nakamichi BX-2 cassette deck(!)- One cover handle fixing bolt very loose - added M4 shakeproof washer to both (schoolboy error by TTI)- First and second soft keys under display intermittent - will probably replace all- One-pixel wide vertical blue line about 10mm from right hand edge of screen - display problem, presumably- Prised open AP02 pod and took some pics - attached- No Rom fitted (empty socket) in AP02 - I'm looking for a 6800 disassembler Rom/pod/code - anyone have?More anon.
