View Full Version : 93c46 rotated or not. My CDH Electronics gear has thrown it's teddy out of the pram again, and has to go back to see Colin, so I'm trying to read it with an Asix Presto, I wired it up as a rotated 93c46 and was unable to read, so tried as a normal one still the same. Would I have damaged it if it was not rotated, and I read it as rotated.
Any help would be appreciated. Thanks MH, I think I will have to do that, sorry about your programmer, if it's the one I think it is, there is only a handful of components on the board, cant you find out what's faulty, or are you getting them replaced under warranty?
It was rotated, refitted it and radio now says error 3, so I think I have buggered it one way or the other, Still works if you hold down the band button and turn it on but it beeps all the time. Maybe it is rotated, did you check on what pin is gnd? If gnd on radio is on pin5 on pcb, so chip is normal, if gnd is on pin7 on pcb, so chip is rotated. Before years i tryed to read one rotated chip as normal, more than times and ofcourse i did'n read it, then i ask a friend and he say that maybe it is rotated and i tryed it like rotated and read it sucsessfull, so there was not problem.
They are going up as well if you look at later listings by the same seller they are more expensive. Error Another CDH man.. Yes I have had CDH gear for about 15 years , the first interface i had had a sine wave generator for doing the early Philips radio's with ER I do not use it very often, now and every time I do I have to remove the token and then re-install the software. Last time I tried it would not re-install, and so I am sending it back for later software to be added.
Thanks for the info on the 93c Read with a LV48 programmer. All rights reserved.
