Connecting uLINK hardware: uLINK ROTATOR
uLINK ROTATOR is an uLINK module which can control any non PWM driven
commercial or home made rotator.
uLINK ROTATOR supports either analog sensor (pot) or pulse counting sensor
(reed contact) direction indicators. There are three relay contact outputs (CW,
CCW and AUX). AUX may be configured as either SPEED (Yaesu style) or
BRAKE (Hy-Gain style). LEDs CCW, AUX and CW on the bottom row indicate
currently actuated relays. Contact current rating is 16A @ 250VAC or 30VDC.
uLINK ROTATOR module uses same circuit design as rotator interface integrated
in the SMD, but on the output has larger relays capable of handling most high
current motors or solenoids. For a detailed description please see the previous
Rotator chapter.
Each SPDT relay contacts for CW, CCW and
AUX are located on top terminal.
Module provides reference voltage output on
REF
terminal for a position sensor (analog)
pot sensor (analog). Specifications are the
same as the SMD reference output. Analog
input (wiper) is connected to the
S
terminal
with common to
GND
. Pulse counting is a
switch between the
P
terminal and
GND.
MANUAL CONTROL
When the is set to AZ, the module displays
absolute azimuth of the rotator in the range of
0-359 degrees. The left decimal point
indicates CCW overlap and the right decimal
point indicates CW overlap when span is
larger than 360 degrees. Any antenna
specific offset is not shown.
Observe safety precautions, do
not touch wires, terminals or
parts, which are, or could be,
under power!!!
