Connecting a PC to the Control Unit
To connect a PC 50 ft. (15.2m) or more distant, follow the steps below.
See Figure 5–2.
1 Plug one end of a D8W cord into the ADMIN jack on the control unit.
2 Plug the other end of the D8W cord into a 355AF adapter.
3 Connect an EIA crossover cable to the 355AF adapter.
4 Connect one end of an EIA-232-D cable to the EIA crossover cable and
plug the other end into the 25-pin male connector on the Z3A2 ADU.
!
CAUTION:
If the PC is in a building outside the main building (control unit location),
you must install an ADU and an additional protector in each building.
The ADUs and protectors provide both the control unit and the PC with
additional protection against lightning, inadvertent contact with power
lines, and power currents induced by nearby power lines. For more
information, see the installation notes packaged with the ADU.
5 Plug one end of a D8W cord into the WALL jack on the Z3A2 ADU and
connect the other end to an ADU crossover cable.
6 Plug the other end of the ADU crossover cable into one of the jacks on a
400B2 power adapter.
7 Plug one end of a D6AP cord into the 400B2 power adapter.
8 Plug the other end of the D6AP cord into a 2012D-50M transformer.
9 Plug the 400B2 power adapter into a wall jack, BR1A-4P adapter, 102
connecting block, or 103 connecting block.
If you plug the 400B2 into a wall jack, make sure the building wiring
has been set up so that the wall jack near the control unit is connected
to the wall jack near the PC.
If you plug the 400B2 into a BR1A-4P adapter, 102 connecting block,
or 103 connecting block, use 4-pair plug-ended cable to connect the
BR1A-4P adapter (or connecting block) to the wall jack near the PC.
