1 - ARXC - GENERAL DESCRIPTION 

ARXC

 modules are ARCO rotator controller accessories for expanded control and extra 

functionality. Modules are built in IP65 enclosures designed to operate outside of the shack. 
ARCO supports up to four chained ARXC modules at the same time. ARXC accessories 
connect D-SENSOR port on ARCO, using only 4 wires of cheap CAT5 cable. When extra 
control cable is not a possible option, ARCO can connect ARXC modules using pair of 
dedicated ARXC.LoRa modules for wireless connection up to couple of kilometers distance.

 

ARXC.REL 

ARXC.REL

 is four (4) external relays module allowing to control remote antenna switches, 

polarization switches, mast preamplifiers or anything what is suitable to be controlled from the 
ARCO user interface, touch screen or VNC for Internet remote control. ARCO uses preset 
buttons for relays control and relays can be optionally set as directional antenna control for 
8-circle or 4-square antenna showing direction on great circle map.

 

ARXC.MAG 

ARXC.MAG

 is magnetic azimuth sensor. Mounted on antenna boom reports true antenna 

azimuth and can serve as a main azimuth sensor when original sensor in the rotator has 
malfunctioned and as a watchdog sensor to alert user that antenna is no longer beaming to the 
calibrated azimuth, that may happen if antenna slips in bolt during high wind or storm.

 

ARXC.LoRa 

ARXC.LoRa

 is long range communication transceiver module operating on ISM band 

converting bidirectional RS-485 communication used by ARCO and ARXC modules to RF data 
and back.
