[GreenKeys] ASR 33 question - stop bits?

[Keith Lueck]

 Hi Wayne -
I remember your post.  
Avoiding the PC jargon, what I'm finding is my unit needs *3* stop bits (prints perfectly), and occasionally produces errors with only two.  I haven't tried one, and I imagine the machine would produce even more errors at that setting.  My machine has an hour meter on it, and it has about 750 hours on the clock, so, I don't think it's worn out (IIRC you can reasonably expect 1500 hours).  I'm certainly no 33 tech, but I did solve a number of problems with this machine by reading the manuals and significant help from the group.  I suppose I'll go searching the manuals - I was being lazy by posting to the group...  I'll concentrate on whatever I can find about the selector in the manuals.  
Thanks,
Keith

Keith,




I just recently sent a post to GK about exactly what you are asking.  




I dont understand the computer settings you refer to, but here is what I have found.




Some 33's will print perfectly with only one stop bit.  Others will need 2 stop bits.  Its related to the conditions of the selector clutch area.  Wear on the drum and shoes and the fine tuning of the selector area.  




Unless you are a 33 tech you probably should just continue using 2 stop bits.




Most 33's I restore can print well on 1 stop bit but sometimes no matter what I do it needs 2.  When sending the 33 always has 2 stop bits due to the distributor faceplate.  




73,




Wayne
