+=====Description=====
+The RocNetNode supports Mobile commands for controlling the GCA-Pi05.\\
+The GCA-Pi05 is designed for gauge **G** locomotives with enough room to hold a RasPi/Pi05 sandwich.\\
+The Raspberry Pi communicates by WiFi.\\
+Startup of Rasberry Pi is not like a normal DCC locdecoder, it takes approx 8-10 seconds.\\
+Therefore, also a small 6 Volt Accubattery should be mounted inside the loc.\\
+The power supply will also take care for charging the battery and switch it off if for a longer period no power is available from the track.\\
+ \\
+=====Features=====
+  * RFID reader for reporting scanned tags between the tracks; Sensor by ID.
+  * 4A Motor PWM output: GPIO 22 and 7-8 for direction.
+  * 2 Smoke generator channels: 7-8.
+  * 6 light PWM channels direction dependent: 9-14.
+  * 6 Servo channels: 1-6.
+  * 2 general channels: 15-16.
+  * Sounds from SD-Card.
+  * Hall sensor for controlling the drive wheel speed.
+ \\
+=====Loco address====
+  * [[:loc-int-en|Loco Interface]]
+    * Bus -> 0
+    * Address -> RocNetID
+ \\
+=====Motor setup====
+{{ http://arduino.cc/en/uploads/Tutorial/pwm.gif?200}}
+  * [[:loc-int-en|Loco Interface]]
+The motor PWM frequency is about 100Hz.\\
+The **maximal duty cycle** can be set as percentage in the **steps** field; 100% is maximal.\\
+**Acceleration** can be set in the **mass** field: 1=10ms, 10=100ms, ...\\
+The number of internal speed steps is fixed at 100 and is spread over the maximal duty cycle set in the steps field; For max. duty cycle of 50% the number of decoder steps must be set to 50.\\
+ \\
+=====Sensor setup=====
+The reported RFID must mach with a __**[[:sensor-gen-en#id|Sensor-ID]]**__ in Rocrail.\\
+This sensor should have its address set to zero.\\
+The ID must be set in this notation: __**[[:can-gc4-en#rfid_notation|RFID Notation]]**__\\
+The Rocrail traces can be used to copy this ID or the __**[[:sensormon-en|Sensor Monitor]]**__.\\
+ \\
+=====WiFi=====
+{{ :rocnet:edimax-ew-7711uan.jpg}}\\
+The RasPi needs a good WiFi USB-Stick to get a stable connection.\\
+In the test environment  an EdiMax EW-7711UAn is used. (€10)\\
+The EdiMax Nano can not be used.\\

+=====Locomotive=====
+For this example a **[[http://www.usatrains.com/usatrainslocogp7.html|USA Trains EMD GP7]]** has been used.\\
+{{http://www.usatrains.com/gif/GP7parts.gif}}\\
+  * Max. 65 MPH (104 KM/H)
+  * Drive wheel diameter is 28mm; One rotation is 88mm.
+====RPM Control====
+===Magnets===
+In the gear-wheel 3 magnets of 6mm ø3mm must be mounted like this:\\
+{{:robvrs:g:3mag.jpg?400}}\\
+===Hall Sensor===
+The Hall sensor can be tie-wrapped on a small piece of PCB which fits beside the gear-wheel in the gear-box of one truck.\\
+After the sensor have been bent in the optimal position it can be fixated with some hot glue.\\
+The Hall sensor will generate three times a pulse for every wheel rotation.\\

+^ DC Voltage ^ Hall Freq. ^ Rotations ^ Scale speed ^
+|  2V |  3Hz |  1 |  10 kmh |
+|  6V |  10Hz |  3.33 |  35 kmh |
+|  12V |  22Hz |  7.33 |  67 kmh |
+|  18V |  33Hz |  10 |  100 kmh |
+ \\
+====RFID Reader====
+The RFID reader can be mounted in the Cylinders (19). Or alternatively in the tank. (20)\\

+ {{:robvrs:g:id12la.jpg}}\\
+The **ID-12LA** in combination with glass responders is fast enough for this gauge.\\
+ \\
+===== Motor distortion =====
+The motors usually are spreading a lot of distortion, which is suppressed mostly on the controller board or decoder.\\
+But the rather long lines to the motor still spread a lot of this distortion,\\
+and in that way making a good functioning of the RFID sensor rather impossible.\\
+One good solution is using VDR resistor (plain 30V type) , mounted directly on the motor connections.\\
+This actually cured my RFID problem.\\
+Picture below shows one of the VDRs mounted.\\

+=====Videos=====
+  * [[https://www.youtube.com/watch?v=qqWY_-H5RcY&feature=youtu.be|Test track at the MGV club in Venlo]] \\ The ID-12LA is fast enough. There is no digital signal on the tracks; Only a AC power supply.
