Joining erthernet cables

[Midwest]

Argh, there are other similar panels in the area, their website suggest daisy chaining.

I can't open that PDF, I'm guessing you're logged in.

Nor can I now; must be a problem with their web site.

If ALL the wires are doubled up with their partners (e.g. blue with blue/white) you don't have Ethernet. But it is permissible to double up brown with brown-white and blue with blue-white since there four are unused except by Gigabit Ethernet.

very informative posts so far, but what has been missed is that the ethernet cables need to want to join, it's all down to karma.

True, SWD...but as you might see from another thread, she has left me!

Here’s a pic of back of panel;

That’s the 12v power supply and rs485 communication(d- d+)

rs485 is also known as multi drop serial coms.
each device on the network has its own address, devices can send and receive info to each other down a single pair of wires.
normally at 1 end, there is a terminating resistor so if you need to extend it then you have to do it from the last device in line and move the terminating resistor to the new end of line device.

You said EX-0R but that switch doesn't say that have you got a picture of the control box.

Dynalite controls couple up with ex-or, dali, etc

It's like being married, you do as you are told by her indoors.........

There is a terminating resistor at both ends.

Sorry for your loss, when's the sea burial?

Sounds like Token Ring.

It’s not clear in this thread, but the existing panel is in the confines of a swimming pool. The replacement needs relocating by about half a meter to the other side of an entrance door, in a more suitable environment.

The original installers quoted panel and part number, which was from Ex-Or. The product boxing states Ex-Or, but the new panel has Philips written all over it. I was a bit concerned, but apparently all this stuff is manufacturer & marketed by all sorts.

It is similar to token ring.
I am not sure how it deals with flow control.

Here’s a pic the right way up;


The instructions show a screened cable terminated, but the wires have been used?
