{TOC} [<-- Web page|https://remoteqth.com/6x2-antenna-switch-control.php] !The hardware !!How to connect Power * Plug DC jack 5,5 outer, 2,1 mm inner size. * Connect 12-15V DC power voltage. Current dependency to connected antenna switch, alone controller about 60mA. !!Front side [https://remoteqth.com/img/wiki-6x2-front.png|noborder] * '''LCD''' - shows selected antenna - first line Input/Output 1, second line Input/Output 2 * '''MENU''' - light button. For activate press button more than 0,5 second. Green light signals if manual control activate. * '''ENCODER''' - rotary encoder primary move cursor, after activate MENU you can select antenna outputs manual or back activate BCD inputs. !!Rear side [https://remoteqth.com/img/wiki-6x2-rear.png|noborder] * '''DC POWER''' - input jack 5,5/2,1 mm size for DC power between 12-14 Volts. Same Power on pin8 ANT outputs. * '''ETHERNET''' - OPTIONAL module for controlled switch manual over simple web page. * '''microSD''' - not implemented. * '''BCD IN''' - band data inputs activate two levels, dependency to JP8 jumper ** HIGH - TTL voltage input ** LOW - grounded input (contains own 1k pull up resistor) * '''PTT TRX''' - grounded activate input PTT from transceiver (contains own 1k pull up resistor) * '''PTT PA''' - PTT continues from TRX to this output for power amplifier. If detect collision between inputs band, this output will be deactivate. * '''ANT''' - six outputs, will be in two levels dependency to preset JP1 and JP2 jumper. Also 12V DC power and ground available. ** ULN if use internal driver ULN2803A - open collector 500 mA each outputs ** UDN if use internal source 12V power driver UDN2580A. !!Left side * From the left side is accessible USB mini connector from Arduino NANO, which is usable for upload new firmware. !Diagram *'''Schematics''' [rev 0.3 .SVG|https://remoteqth.com/hw/6x2-antenna-switch-control-03-sch.svg] *'''PCB''' [rev 0.3 .PDF|https://remoteqth.com/hw/6x2-antenna-switch-control-03-pcb.pdf] *['''Interactive BOM'''|https://remoteqth.com/hw/6x2-antenna-switch-control-ibom-03.html] *'''Block''' [https://remoteqth.com/img/wiki-6x2-block.png|noborder] !Board preset Before opening has to be '''removed eight screws''' **'''three''' on left side **'''three''' on right side **'''two''' on rear side, near double cinch. !!
