ARCO Extension: 4 relays

Technical description ARXC.REL

ARXC modules are accessories for ARCO rotator controllers that provide advanced control and additional functionality. The modules are mounted in IP65 enclosures designed for operation outside the shack. ARCO supports up to four simultaneously daisy-chained ARXC modules. ARXC accessories connect to the ARCO's D-SENSOR connector, requiring only 4 wires of standard CAT5 cable. The asynchronous serial data transmission (RS-485 interface) increases the electromagnetic compatibility. If connecting an additional control cable is not possible, ARCO can interconnect the ARXC modules with a pair of dedicated ARXC.LORA modules for a wireless connection over a distance of several kilometers.

The dimensions given below do not include protruding parts (e.g. lugs for screw connection).

Note: To operate the ARXC extensions, a software update of the ARCO controller may be required, which is available on the microHAM website.

Application description ARXC.REL

The microHAM ARXC.REL is a module with four user-programmable relay outputs for control of antenna and polarization switches, mast preamplifiers or other devices enabled, which can be controlled via the ARCO user interface using a touch screen.

Configuration is also done directly on the ARCO and allows for three categories:

• BCD-N
• 1-of-N
• TOGGLE 1-4

In order to recognize and properly control a particular ARXC.REL module, each module must be assigned a unique address. The address is set by combining two DIP switches according to the "drawing" on the PCB next to the DIP switch. It is possible to set up to 4 different addresses. Each ARXC.REL module then has its own setting in the ARCO system menu on the respective ARXC 1 - ARXC 4 tabs.
