CIU power pins

[robbot]

Hi,
I need to add another power TN to my CIU but can't seem to find it documented anywhere. All I can find is one power TN. Surely there is the provision for extra power like the 2250? Any Ideas?
Thanks

Two TNs programed as PWR on a digital card cross connected to the Red/Orange and Red/Green pair of the console cable. When you cross connect the TIP of the first and second TN goes to the Red/Orange pair. The RING of the first and second TN goes to the Red/Green pair.

Just to let you know:

The CIU only has 1 power. 2 TN + 1 PWR

If you connect the second power the CIU will not come in service

Thanks for that.. I have it from ascom (finally) that these are the pins below. The CIU takes it's power from the +AUX and -AUX. It is different to that of the 2250 which uses the 3rd TN.


25 pair cable
from console
to MDF DB 25 on CIU

26 (w-bl) 14
1 (bl-w) 2
27 (w-or) 15
2 (or-w) 3
32 (r-or) 19
7 (or-r) 7
33 (r-g) 22
8 (g-r) 10

See the NTP on atttendant console for the + and - AUX connections as the tip and ring are tied together.

Aparently this extra power will stop GPF's on the Smile software and other glitches like going in and out of night mode..time will tell though.
