ITA-6
Identification Numbers & End of Line Jumpers
Each Comlink-2 card used to communicate parameters between ITA-6 units
and the main controller must have a unique identification number. This
number is configured using jumpers on the card and should be assigned
before plugging the card into each unit. To do this, use the three jumpers
(marked X100, X10 and X1) on the card (i.d. numbers can go from 0 to
199). Use X1 for units, X10 for tens and X100 for hundreds. In each
case, place the black jumper horizontally over the two pins corresponding
to the digit required.
The ITA-6 network operates on two communication lines. One line links
the ITA-6 units together to the main controller and the other line links
temperature controllers to a computer (this second line is optional). Two
jumpers on the Comlink-2 card are used to identify the end of line for each
communication line. The ITA-6 communication line uses jumper JP5 and
the computer line uses JP4. Use pins 2 and 3 for YES and pins 1 and 2 for
NO. The following diagram shows a typical connection with the appropri-
ate jumper configurations.
