[GreenKeys] Want to try 28 selective calling and maybe motor start stop

[Paul Heller]

I’ve read the stunt box brochure. In the example in there, figs-H-ltrs sets the zero and depression code bars so the 28 does not print. Three one (or more character) will select the specific 28 to print. All other printers will not print. CR-LF-Ltrs resets all the printers. 

I find it interesting that the example uses CR-LF to reset the machines. That means the ctrl-H sequence needs to be sent for each line. I’d choose a different sequence for the reset. 

I’d like to replicate this. I’ll put three 28s on a loop. Two will be set up for selective printing. I’ll use one letter to identify each one (let’s say A and B). 

If I understand it correctly, I send figs-H-ltrs to suppress both machines, then A or B to select the machine I want (let’s say A), then send my traffic. A will print, B will not. (Somehow even if the traffic contains a B in it, the B printer won’t start printing. I guess it only listens for the one character that follows the figs-H-ltrs? This part is not described in the brochure). When I am done I send CR-LF-Ltrs (as I said, I’ll change this) and both the A and B printers reset and print anything that is on the loop. 


I guess I need a bunch of function bars and the appropriate kinds of function pawls and levers and some description of how to keep the printer supressed even if it’s select code arrived in the traffic because this is not explained in the brochure. I’ll also need function latches and shift forks and who knows what else. If I want to experiment with motor on and off I’ll need some switch blocks. 

Anyone have the parts and guidance on how to set it up? I can always use trial and error but need the parts. 

Thanks for any help anyone can provide.
