2. LONG DISTANCE TRANSMISSION

A) Twisted-pair transmission between point A to point B:

3 kilometers at maximium between two points when 3 units are mounted closely side by side at each point.

With each additional unit, the distance is reduced by 100 meters.

B) Twisted-pair cable between 6 points (special case of 1-D)

2 kilometers at maximum with twisted-pair cable between each point.

4 sections at maximum with fiber optics; 1 kilometer at maximum for each section. Total distance within 10 kilometers.

POINT B

* Marked units are located at the end of transmission line via twisted-pair cable. Short across the terminals 6 – 7 with the jumper pin provided

with the units.

3. INTERSECTION

When units cannot be connected in serial, use a pair of units of code"7" at the intersection (marked with *) or model DAL4.

4. COMBINATION WITH MODEL DAL4

2 kilometers max. between two DAL4 units. 1 kilometer max. when there are other units between the DAL4 units.

Total number of DAL4 on the transmission line must be 6 units or less, with the total distance 10 kilometers max.
