Hello

I would appreciate it if anybody can help me how to connect L88 (60883) to CS2 (60215) when at the same time I have already connected a booster (60173) at CS2. The manual of L88 at page 15, describes to connect L88 to the booster connection of CS2, but this port is already occupied by my booster. The only way is to purchase 60125 and what this unit does?

Thanks in advance
Tasos

Yes, if you use the Booster port on your CS2 you need to buy a Terminal 60125. The Terminal simply expands the available amount of ports. The Terminal allows you to add additional S88 Links, boosters, Mobile Stations etc. to your system. To attach the Mobile Station you will need a converter cable (60124).

You have the option to use the extension cable (60126) and move the Termnial further away from the CS2. This will give you the option to place a booster near the circuit that it powers or perhaps have a plug for a Mobile Station away from the CS2.

Terminals can be connected to other Terminals and the chain can be 100 meters long. You can extend the Terminal's reach with the 60126 extension cable.

I have the same situation but I have only attached the booster to the 60125 and to the CS2. My read of the 60125 and 60883 manuals are as follows (but would like to have confirmation).

60883 manual, page 15 states 'Connect the link 88 directly to the booster connection of the CS2 or to the 60125. The 60125 manual only shows a picture of the connection and it appears to be to the input connection on the CS2. I suspect that the 60125 can be connected to either the input or the booster connection on the CS2. My guess is that the 60125 parses messages from various devices to the CS and can communicate through either channel to the CS2.

Any document that shows a 9 pin glug being forced into a 10 pin socket should be looked upon with skepticism

That aside the 60125 Terminal document is dated 02/15 which is before the 60883 Link S88 was available

The list on the left of page 3 (under the (4) ) should be updated .
- Mobile Station - 60651/60652/60653 (and Trix Variants) - needs 60124 7<>10 pin adapter as shown
- Booster - 60173/60174/60175 (The 60172 never saw the light of day)
- Connect 6021 - 60128
- Link S88 - 60883

Note: The 60145 is to replace the 60125 with no other changes than the colour - It would be nice if the manual was updated .....

NO

The port labelled "Booster/60173/4/5" is a 7 pin connector and may be used for the SAME devices that may connect to the 60125(60145) but not the 6015/60145 itself

The 60125/60145 cable has a 9 pin plug and plugs int0 to System Bus (9 pin) socket of a CS2/CS3

Note: The 60125/60145 does have a 9-pin socket , this is for extending the system bus and NOT for devices
Options are
- Another Teminal (includes cable)
- A Slave CS2 (needs 60123)
- the 60126 extension cable (for either of the above two devices & other extension cables up to 100m)
You cannot use the The Terminals socket (leaving the plug unplugged to anything) and a 60123 cable to work backwards from a slave CS2.

My guess is that the 60125 parses messages from various devices to the CS and can communicate through either channel to the CS2.

The System Bus is bi directional, any device may send or receive data.

One important function of the Terminal is to correctly "electrically terminate" the bus this ensures clean and reliable signalling.


In general use the number of pins in the connector as a guide.
Currently with the following exceptions
a 60122 (MS-II Hub) cannot be used with a 60125/45 even though it will physically plugin with a 60124

I don't know why, but it constantly amazes me how convoluted the architecture is on the Märklin side, with its seemingly too many variants of similar signaling systems. Reading that dogs breakfast of part numbers, names of units, and signaling protocols, its no wonder even the casual user can be confused. I keep getting confused and I'm a trained electrical engineer and software developer with several advanced degrees.Blushing

Why is there such variation on the equipment vs a single bus system that allows components to be daisy chained at will?

There is a simple bus, the CAN bus.
There are CAN connections with 6 pins, 7 pins, 9 pins, and 10 pins. This adds a bit puzzling fun to the simple CAN bus concept.
Are there no 8-pin plugs yet?

The 60212 provided a 8->10 cable for (alternative) track connection using a 24088,60111,60115

Two prime reasons

1) to distinguish main bus and terminals nodes from device nodes due to electrical termination reasons
2) accommodate alternate power supplies (specifically for Mobles Stations (10 pin)

Its pretty simple really.
Core Bus
- The core bus infrastructure uses 9 pin - terminal (60125/60145), extension cables (60126)
- This is throttled to 6 pin (60123) when using additional slave Central Stations (who do not need power from the master - and, if needed, provide the needed power to further downstream nodes.
Note: the Slave CS2 also acts as a terminal note with 3 device ports (sure 2 are exclusively for Mobile stations).

Devices
- All "devices" have a 7 pin connection - the Mobile Station needs the 60124 to achieve this because it can "natively" get its power from a railbox or in the case of the 60651/60652 , it actually needs wires in the cable to provide power to the track.

Just because you can, doesn't mean you should, does it? (pun intended).

I'm a total layperson on CAN bus, in that all I know is its a micro-controller communications bus initially developed for automotive use.

Would it not be possible to have one cable with the full 9 pins, and have all devices internally do the right thing to sit on the bus and terminate if needed?

Is it possible to get longer cables for than the Marklin 2 meter ones? I'd rather buy one 10 meter one than 5 2 meter cables.

I am replying to your post #5 above. When I suggested connecting the 60125 to the input port of the CS2 I had not counted the number of pins on the other ports of the CS2. No others port have 9 pins and so the 60125 can only be connected to the input port. THis is shown on page 2 of the 60125 manual. Again, now counting plugs, I see the 60883 and boosters have 7 plugs and so (4 devies) can plug into the 60125.

Thanks for causing me to count the pins.

Regards
Harvey
