I just bought an ESI S-class system (Norvegence CCS) on ebay to help conserve the costs of a small business. I am trying to connect the system up but don't have a wiring diagram for the port card. I am an electrical engineer so I opened the case and determined the following:

pin 1,26 station 1
pin 2,27 station 2
pin 3,28 station 3
pin 4,29 station 4
pin 5,30 station 5
pin 6,31 station 6
pin 7,32 station 7
pin 8,33 station 8

CO 1
tip - pin 20
ring - pin 45

CO 2
tip - pin 21
ring - pin 46

CO 3
tip - pin 22
ring - pin 47

CO 4
tip - pin 23
ring - pin 48

Can someone verify this? Also, what pins are the analog channels located on?

Any help would be greatly appreciated. I would love to have a copy of the wiring diagram and the installation guide, but it seems that this material is not easily attainable.

Does anyone have any tips for my install? Lastly, is there a way to get esi-admin?

Thanks,
Tom

So far you're correct, station 1 = extension 100, station 2 = 101, etc until 107, then you skip some pairs til you get to the analogs. Extension 124 and 125 are your analogs. They are at pair 13 and 14 on the 66 block.

ext 124 -> black/green, green/black (pin 13, 38)

ext 125 -> black/brown, brown/black (pin 14, 39)

I wouldn't bother with ESI-admin. All of the programming for a system this size is easier to do through a phone than thru the gui apps.

p.s. somebody jump in and correct me if I'm off by a pin, I'm doing this from memory.

Thank you very much for your post.
