The number and kind of uLINK modules used as control boxes depends on the configuration requirements and
style of construction. If the control wires from all antennas, switches, and rotators go to the shack or a common
"equipment room" all uLINK modules should be placed in the shack as well. If the goal is to minimize wiring a
more viable solution is to place the modules in the field close to the RF boxes being controlled. In that case the
wiring requirement will decreases to the uLINK cable and power. However, this approach means that the usage
of outputs will not be optimal (unused outputs) and installation will need a water proof boxes to house the uLINK
modules. The optimum approach will be different for each antenna farm.
Once we have a block diagram for the installation, we can assign Control boxes to the RF boxes. We need to
recognize control type and whether an antenna needs DATA, ROTATOR or RELAY control. With RELAY control
we need to determine what functions are to be controlled – whether we will be controlling attributes like direction
(ANT type), frequency dependencies (FRQ type), PTT relationship (SEQ type), manual control (MAN type) and
the number of control wires.
There is no rule for addressing uLINK modules other than address must be greater than 32 and must be unique.
