Hi,

I using the ADTPro Client to transfer some software to my Apple II.
I am using the Audio client. And I can transfer ProDos and the Audio Client. But if I press D or R to send some dsks or lsit the dir the mic level goes on max. settings 4 bars up for a second and then nothing happend. On Apple II screen stand: Waiting for host reply, esc cancels. On ADTPro Client stand No activity. What else can I do? Cables are new, level changing did not work.

I'm using an MacBook Pro from 2010.

regards Christopher.

Re: ADTPro and Audio

You've chosen the most temperamental combination of machines and communications methods. Audio in general is difficult to get tuned correctly; it seems most difficult on Macs.

What we know is the audio-out (Mac to II) is correct; that is a completely one-way trip from the Mac to the II when loading ProDOS and the client. The other direction (II to Mac) is not being "heard" correctly at the Mac end. This is often because there is not enough amplification. There are many settings to boost the mic sensitivity; I list a couple of them on the ADTPro website. From your description, it sounds like you only see four (out of a possible 15?) bars on the input side? Is that correct? If so, you'll need to get it amplified quite a bit more to make the connection.

Re: ADTPro and Audio

Thank you for this diagram:

1--\ /--16
2--/ \--15
3--\ /--14
4--/ \--13
5 -------- 12
6 -------- 11
7 -------- 10
8 -------- 9

I need the Terminal settings, so I have connect 1->15 2->16 3->13 4->14 5->12 6->11 7->10 8->9?
And if I need Serial / Modem settings I have to useing no jumperblock or wires?

Found another diagram:

.----------------------------------------.
| Jumper Block Wiring |
|----------------------------------------|
| SSC signal MODEM (pin) TERMINAL (pin) |
|----------------------------------------|
| TXD TXD 2 RXD 3 |
| RXD RXD 3 TXD 2 |
| RTS RTS 4 DCD 8 |
| CTS CTS 5 DCD 8 |
| DSR DSR 6 DTR 20 |
| DCD DCD 8 RTS 4 |
| DCD DCD 8 CTS 5 |
| DTR DTR 20 DSR 6 |
|----------------------------------------|
| Note that RS-232-C signals on the SSC |
| use negative-true logic; that is, they |
| are true at 0v and false at +5 volts |

That's correct. Only so much you can do with ASCII art. Wink What you do is you wire up a 16-pin socket with this set of connections, then you rotate it 180 degrees and plug it in to get Terminal vs. Modem settings. So depending in which way this is oriented when plugged into that socket, you either get a DTE or DCE connection.
