Cabling - Activant Dimensions Getting Started

Cabling

Each device connected to the main computer system (CPU) such as terminals and
port printers, require cables. See Dimensions Wiring Configuration available
from Dimensions support for details. You will need to determine the correct cable
length for each device to the nearest 20 feet. When measuring cable
requirements, be sure to allow 4 feet at both ends for the cable to reach under
counters (floor to counter top).
1. Using your site map, determine how each cable run will be strung (i.e.,
through walls, overhead, etc.). Each terminal and port printer (addressable
printer) must have a cable connecting it to the main computer. WARNING:
Do not string the cables over fluorescent lights or near any magnetic field.
This causes electrical interference with the current in the cables. Also, be
aware of obstructions such as cinderblock walls, beams, posts, ceilings, and so
forth.
2. The cable run for each device attached to the main computer system goes from
the wallboard to a terminating walljack. See the illustration below. The
wallboard must be located 4-6 feet from the main computer and is normally
attached to the closest wall. For example:
3. The terminating walljack should be placed as close as possible to the device
(terminal or printer). The terminating walljack has a receptacle like the plug
in a telephone jack. The narrow side should be pointing down so that dirt and
sawdust does not accumulate in the receptacle, preventing a good contact with
the plug end.
4. You may want to string several extra cables into areas of heavy computer use
to accommodate possible later expansion.
5. After you have determined the layout of the cable runs, determine how long
each cable needs to be. You should measure from the wallboard to the
terminating walljack. Remember to leave several extra feet on each end. It is
easy to cut cables shorter if needed but the cable cannot be lengthened.
6. You may want to consult with your local building inspector or contractor to
insure you are meeting all building codes.
7. Each cable must be numbered on each end with stickers or tape. Dimensions
prefers that the numbering begin with 3 and go up from there. For example:
