Hi All
I have read a lot of topics about S88 connection to CS3 from Arduino. I'm looking for someone who can confirm that I can connect an Arduino nano at the end of my S88 chain via the RJ45 connector. I have no S88Link unit in the chain - just pure 60881 units.
In case it's possible - how is the pin mapping? I have read the "Arduino used as an S88 occupancy detector board" at "Rudysmodelrailway" website but is still confused how the connection is done and if at all is possible to combine 60881 units with one or more arduino's at the same time.
Best regards..

Hi Tue/All, You may want to read the article below by Mike Jagoe. Arduino Based s88Hope you find it useful. |

It's a really good article, and he really solves some of the problems. But i'm stuck with a basic problem about how to "physical" connect the arduino to the S88 bus on my CS3+. If I used a CS2 or S88Link or ECoS it would be easier because the access to their S88 bus is not via an RJ45/PDS cable, but directly to named pin on the hardware. I haven't seen anyone do the the connection to an CS3+ S88 Bus. And that worries me. I'm also curious if I can mix the arduinos with marklin S88 units on the same unit (cable). Best Regards /Tue

Please note that the S88 bus on a CS2 is using 5 Volt and that the S88 bus on a CS3+ is using 12 Volt.
I guess that 12 Volt on an Arduino will kill it.
If you are using an Link88, you will have the opportunity to reduce the voltage on the S88 bus to 5 Volt.
Link88 can be used for CS2, CS3 and CS3+ and is connected by mean of the CAN bus.

Per Thanks Per - I was (almost) aware of the difference in voltage. But do you hereby say that the only way to interface from Arduio is via the CAN bus through an Link88? Best regards /Tue

It is not the only way, but if you are looking for an easy way of connecting an Arduino to a CS3+, then I will recommend a Link88.
Best regards
