Sorry, Matt. I did mean the 401. Dyslexia must be kicking in on me.
Looks like the dyslexia is hanging around for a spell, Ed.
Here's where we are at:
I took an old amp. connector and made all connections straight to the KSU.
The good news:
1. The talk path is completely clean, which I seem to remember was a problem in the last iteration of this excercise.
2. The IC (line 5) light lights!
The somewhat good news:
1. I can hear the relays click with each button press.
The bad news: I was only able to get a buzzer to work on signal pin 0, and then only about every 8 pushes of "0".
The bizzare news: I tried random signal out pins (0 (worked occasionally), 3, 4 and 9). No buzz. But, hooking a voltmeter between AG and the signal pin consistently displayed around 11vac. The bizzare thing: It stayed at that voltage till I pressed another key. Maybe the card needs the buzzer to drain down a capacitor or something, just guessing.
So, I've got my voltage, but it apparently doesn't have enough amperage to buzz the buzzer. Is there even a remote chance that ITT required a special, low current buzzer with this card?
Open to any and all ideas...
Thx
Matt
