+ | **__The characteristics of the card are the following__** | ||
+ | |||
+ | * Dimensions 150mm x 100mm | ||
+ | * External power supply 12 Volts, regulator on board 5 Volts for Raspberry Pi integer with LM2575 or KIM055 | ||
+ | * 2 radio way repeater (RX and TX) and also one way to transponder or Link by radio | ||
+ | * Audio level ajustement with potentiometers (In/Out) | ||
+ | * Connections to transceivers by pin (Dupont) or by RJ12 connector (6P6C) | ||
+ | * Audio isolation by transformers | ||
+ | * Connect to USB audio cards by stereo audio Jack or pins (Dupont) | ||
+ | * LED Indicators for PTT and SQUELCH detection | ||
+ | * Normal or reverse SQUELCH detection selectable by jumper. | ||
+ | * 4 outputs on relays with LED indicators | ||
+ | * 4 digitals inputs | ||
+ | * Protection by opto isolated on digital Input and Output. | ||
+ | * 4 analogs inputs (0-3,3 Volts) | ||
+ | * 2 1WIRE ports, | ||
+ | * 1 RS232 port | ||
+ | * 2 I2C ports | ||
+ | * External Watchdog with ajustable timer set by solder jumpers. | ||
+ | * 40 pins connection for Raspberry Pi | ||
+ | |||
+ | The //SVXLink Card// board supplies the power to the Raspberry Pi thru the 40 pins connector. | ||
+ | The recorded consumption of the board //SVXLink Card// are the following ; It's for a configuration with one USB soundcard (RX + TX): | ||
+ | * Standby : 150 mA / 12V (soit 1,8W) | ||
+ | * Transmitting : 200 mA / 12V (soit 2,4W) | ||
+ | * 4 relays switched : 350 mA /12V (soit 4,2W) | ||
+ | * Transmitting and 4 relays switched : 390 mA/ 12V (soit 4,7W) | ||
+ | |||
+ | ==== Main Features ==== | ||
+ | * Repeater controler with Raspberry Pi and [[http:// | ||
+ | * Squelch detection (Large voltage 2,2V to 12 V) | ||
+ | * Statuts leds indicators (Squelch, PTT) | ||
+ | * Isolated Audio interfaces with adjustable level for 3 way. | ||
+ | * External power supply between 9 and 12 Volts | ||
+ | ====Secondary fonctions, options ==== | ||
+ | * 4 outputs relays switch 400Vac / 4kVA, with led indicator | ||
+ | * 4 inputs opto isoled | ||
+ | * 4 analogs inputs adjustable (with voltage divider) | ||
+ | * (or) 2 inputs for smeter (signal level receiver) | ||
+ | * Temperature sensor on board | ||
+ | * Protection against unexpected freeze (watchdog for reboot) | ||
+ | * Availability of bus [[https:// | ||
+ | * Availability of bus SPI ([[https:// | ||
+ | * Availability of bus [[https:// | ||
+ | * Availability of bus [[https:// | ||
+ | * Availability of 4 remaining GPIO availables on Raspberry Pi | ||
+ | ==== Features of repeater ==== | ||
+ | |||
+ | The installed software is [[http:// | ||
+ | * Power on repeater, by radio way (DTMF rolling code ) | ||
+ | * Smeter from received radio stations | ||
+ | * Voices announcement of locals measurements | ||
+ | * Temperature of board environment | ||
+ | * Analogs inputs | ||
+ | * Status of digitals inputs | ||
+ | |||
+ | ==== But why all this ? ==== | ||
+ | |||
+ | |||
+ | Here are examples of applications: | ||
+ | |||
+ | * The temperature sensor mesures the repeater cabinet, it could very well activate a thermal resistance to maintain the cavities at good temperature. And transmitting with voice the temperature. | ||
+ | * Possibility to change output repeater power in low power with switching relay. | ||
+ | * Possibility to switch off power supply to switch in battery mode. | ||
+ | * Analog input can mesure smeter but also for measuring the supply voltage or the battery voltage, a relay may then cutting battery power to preserve them. | ||
+ | * This will connect a LCD / GLCD screen, buttons on the I2C port, a real human/ | ||
+ | * Inputs digitals can indicate the 230V power supply or the door of the cabinet status. | ||
+ | * Repeater send by mail every evening a reporting of activity. | ||
+ | * A web page show measurement | ||
+ | |||
+ | You'll understand the possibilities are great and belong to your imagination. | ||
+ | ==== How SvxLink manages it all ? ==== | ||
+ | |||
+ | It's very simple, it handles only the PTT and squelch detection switching and audio mixing. It also manages direct radio link or through echolink and voice synthesis. | ||
+ | |||
+ | For everything else it's us or you to code. The Linux world will allow all that, for example, repeater display will manage with a small program that will read the LOG file of //SVXLink// and display it on the screen. | ||
+ | |||
+ | All state variables or measures can be shared between applications. | ||
+ | CRON can enable to schedule scenarios at time, for example sending repeater information an email every day at fixed time of the day. |
