Awhile back we got a box full of old API console cards...we racked up the 6 channels but also in the box was a 525C. At the time I didn't have a lunchbox and sort of forgot about it until I was digging around and found it today. It's a 525C. 2 Huntington era, 1 Farmington. I put it in a Lunchbox, and nothing. Doesn't appear to be getting input or output.
So, I thought maybe the pin out was different and it appears it is. From John Klett, here's what he says the pinout for 525 and 525C is:
1 = Chassis Ground
2 = Output High
3 = Output Low
4 = Shield Ground (Power Common) *
5 = Input High
6 = Input Low (Power Common) *
7 = Stereo Interconnect Input **
8 = Stereo Interconnect Defeat **
9 = Factory Test Point
10 = Meter Lamp Supply Input High 24V 30mA
11 = Meter Lamp Supply Input Low
12 = +15Vdc Power Supply Input 60mA max.
13 = Power Supply Common
14 = -15Vdc Power Supply Input 60mA max.
15 = Spare
And the standard now:
1 chassis ground
2 output hot
3 low level output (not really used)
4 output cold
5 Sheild ground (0V)
6
7
8 Input cold
9
10 Input hot
11 compressor link
12 +V power
13 0V power common
14 -V power
15 48V phantom
