SUSI Cables

Not being an electronics expert I wondered if some kind person can explain to me a few things about these cables:

1. Why are they used in preference to more typical Massoth/LGB/etc. connecting wires & plugs?
2. Are they actually called SUSI cables or is there a more technically accurate term for the connectors &/or cables?
3. Is there some magical tool or process that allows the SUSI plugs to be removed from SUSI sockets without resorting to pulling on the 4 wires (and so risking removing said wires from the SUSI plug which remains firmly rooted in the socket)?
4. Does anyone have a link to a supplier of spare SUSI cables or the plugs/wires/crimpoing tool needed to make such cables up?
5 Is the correct pronunciation "S-O-O-S-I" (based on the "single consonant, long preceding vowel" rule) or "S-U-S-S-I" as I was told recently?

As you might infer from the above, I have mixed feelings about these little blighters....

Thanks in advance

If you knew SUSI, like I know SUSI...
(Admit it, you are singing along..)

To answer:

1. Power and data, same cable..

2. 'SUSI' is an acronym (surprise!) for 'Small User System Interface', I believe the connectors are part of the 'mini CT' family of connectors.

3. No, but pulling on the wires is bad-form, and can end in tears! - A small screwdriver, or knife-blade to tease them apart, is better.

4. I don't. Mark, at Garden Rail Outlet, might do them?? I have not looked for suitable connectors, or tooling, sorry. - I may have a few spares you could have..

5. I pronounce it as the girls name 'Susie'..

SUSI Serial User Standard Interface

It is based loosely on a modified version of the industry standard SPI** ( Serial Peripheral Interface) Dietz developed what is known as the SUSI interface, 4 wire, two for power GND/POS and two for Data/Clock, which runs at a slower Clock speed to allow decoder’s to communicate with multiple SUSI devices which is at present set to three.


Full details can be found here….http://www.dccwiki.com/SUSI

and here

A pair of Pin Nosed Pliers to grip the connector will ease their removal (far better than tugging the wires!)

Try here for replacements

For those of a Technical inclination, it is possible to use the SPI structure to communicate with a SUSI device! ;)

Susie - as in airline coupling twixt tractor unit and trailer! I still have one hanging up in the shed from my TW9 reliant.
 
Thanks guys for the info.

I have tried small pliers and forceps / tweezers to remove the plugs but with varying degrees of success. I think the next time I have to install one of these cables I'll cut a small vee-shaped notch in the socket so I can use a pin or needle to help ease the plug when it needs to come out.

Cheers.
 
I do indeed have them available. Also adaptor boards to allow for multiple connections.

I pronounce it as su-zi. I also pronounce Massoth as Mass-oth not as some people do Mas-sooth (which is incorrect - never has someone at Massoth pronounce it that way)..
 
Yep I will have some there.

Maplin do the correct tool for this job, look for FD54J Extraction Tool. I got one yesterday for £2.49 once I knew they existed. No notch cutting required with this little tool. It is basically a set of Tweezers but the ends bends in themself to grab the plug. Clever.
