Dear Members.
Do you know where could I find the schematics of an analog trunks PBX board called "DX2E - 4ASTU - S2".
It is part of a Nitsuko / NEC BPX system called 124i
I have found this link with technical documentation, but there is no schematics.

The reason is...
tda1085
Hello,
I am looking for a chip similar to TDA1085. It's closed loop and can control an Universal Motor (the one inside many domestic tools).
The question is, do you know similar chips. The problem with the TDA1085 is that it needs a tachogenerato rto close the loop, but my motor...
Re: E1 / T1 Bibliography
Yes, but it covers only a small part of the entire specification. It has been the first introduction, and after that I've read some parts of Bellamy's "Digital Telephony".
I need more.
Thanks anyway.
E1 / T1 Bibliography
Hello,
I'm looking for a good book that covers E1 (and T1 if possible) in dept. I know Bellamy's "Digital Telephony", but it's difficult to extract exact information about E1; rather, this book explains some aspects of E1 as real examples of the discussed topics.
What I'm...
Hi friends,
as I ask, do you know which protocol uses an Spanish Ford Mondeo?
The connector has the following wires:
4: Black
5: Black/Orange
7: White/blue
16: Ornage
I've seen on scantool.net that ford uses PWM, but it seems that this car is using ISO 9141.
The car was made in 1996. It's...
Usualy, this kind of EEPROMS have tree or four signals to configure an address. There are two signals (I2C bus signals) that are common to all the memories, and are connected to the microcontroller. You have to force a different address to every memory in order to share the same bus.
The access...
I don't know many things about this subject, so I'm searching information only.
I think that in equipments with linear power supplies these things are different to switched power supplies ones.
In MY case, earth MUST be connected to the chassis of the device, this is clear. Its serial port...
Yes, you are right, but my question wasn't well expressed.
I would like to know how to join the local zero potential inside one equipment with the mains earth.
I've seen in several audio equipments a diode bridge for this purpose.
In my device, I have a linear power supply with a transformer...
This is a topic that I don't understad at all.
I've been looking the web and, by now, this is the best link found: **broken link removed**
but, do YOU know better sources of information about this topic?
Thanks a lot,

Couldn't you send an schematic ?
I don't imagine what is your problem.
Maybe you will need to pass the CLK trough an AND gate (pico gate from Fairchild for example) and the CLK~ through an NAND pico gate to have similar delays between the two.
There are gates of about 2 ns of delay (measured...
