The final act of the WNO Area Group Meeting was the cutting of the Anniversary cake. It seemed such a shame to cut the MERG Logo’d cake but Bob Vetterlein, accompanied by the other Committee members, wielded the cake slice with aplomb and the cake was enjoyed by all.\\ | The final act of the WNO Area Group Meeting was the cutting of the Anniversary cake.

+ | {{ : | ||
+ | For the benefit of some newer members, Peter gave a short overview of principles of CBUS. However, the core of the presentation covered everything from the Classic CBUS modules through Second Generation to a more detailed description of the CANMIO series and all its derivatives including the daughter boards. Pete used the Kit Locker to show the modules and the power of the " | ||
+ | He also showed how to find what has been developed by using the software wiki - here is where CBUS modules and daughter board that are not available as kits may be found. This stimulated a highly interactive session with many questions. This presentation was well received by the members with many saying that their plans for a CBUS implementation had been reinvigorated. | ||

+ | In the afternoon, three of the LWMRS club's exhibition layouts were running: Duxbury 00 gauge finescale DC / CBUS; Kimble 0 gauge DCC / CBUS and Kineton n gauge finescale DCC / CBUS enabling members to see practical implementations of MERG technology. In addition John Gowers' | ||

+ | This allows members to have an informal get-together before we settle down for the morning’s proceedings. | ||
+ | |||
+ | **Mike Plowman** welcomed the members and introduced the theme for the 2019 – **<color # | ||
+ | |||
+ | This meeting concentrated on a recap of the CBUS. Mike described the basic principles of the CBUS system – the need for the twisted pair, continuity of the bus and the termination resistors. He showed the concept of the producer / consumer model and how events can produce actions on specific modules attached to the CBUS. The benefits of the four-wire bus were explained and set the scene for **<color # | ||
+ | |||
+ | Jeremy, with his twenty years’ experience of CAN, was able to show the structure of the “messages” and the way they are prioritised on the bus. He estimated that on a typical CAN bus, where messages from sensors and actuators are passing every few microseconds in both directions, that the bus is about 80% utilised compared to a CBUS which is probably about 2% where messages pass every few seconds. | ||

+ | Another well attended meeting of the WNO are group took place at the Leamington and Warwick Model Railway Society clubrooms on May 11th. | ||
+ | The members are encouraged to gather at 9:30 to allow time for our signature bacon rolls, a drink and an informal chat before the meeting gets underway. | ||
+ | With both our regular cooks away, we needed to make some adjustments to our front of house team. | ||

+ | Since it’s inception, we have encouraged an informal and non-judgemental approach to the proceedings allowing (and indeed encouraging) members to ask any questions that occur to them. There is always an amount of banter between the members as characterised here by the laughter than can be seen in this photograph. | ||

+ | {{ : | ||
+ | |||
+ | He selected a set of modules for his demonstrator: | ||
+ | A USB4 for interface to a computer – he recommended that FCU be the only way considered to configure CBUS modules; a CANPAN as a “Producer” and two “Consumers” – A CANSERVO8c and a CANMIO – OUT. | ||
+ | He explained the function of each of the modules and the reasons for selection. | ||
+ | He then introduced FCU and showed how it could be used to configure each of the modules, adding events and making things happen – servos moving, LED’s illuminating driven by feedback. | ||
+ | This was a highly interactive session with many questions posed and answered. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | In the afternoon, David Roberts presented “Power Supplies & Wiring for CBUS”. Besides giving a comprehensive description of the types of power supplies available, he emphasised the safety aspects of choosing a power supply and also the appropriate wire sizes for the power and CBUS installation. | ||
