that many numbers can makr upi go blind

1 1
2 3
4 9
5 11

use 4 wires from the 45.. connections 1 and 9 are side by side on the top of the db9.. green and red.. skip the next two connections (2 and 8) connect blue and orange.. your done...


if you have a csu.. blue and orange to the 1 and 3 and green and red to 9 and 11


since 90 feet away transmit is one wire and rec is one wire, (common at the smart jack) green can be on the left or right and so cha blue..



for a loop back just splice green to blue and ora the red..

that's a great set of numbers from gibb, keep them, they may come in handy.. we have 46 pri's here and i wired all the dn'9.. along with a few 100 other installs... almost got that one down
