Protel Training Manual

[Lucrecio Poinson]

Thisdocument is the training manual for Protel 99 SE PCB design software. It contains chapters that describe the PCB design process, the PCB editor workspace, creating a new PCB, transferring design information to the PCB from other software, setting up PCB layers and design rules. The manual provides instructions for using key features of the software and includes exercises for readers to practice.Read less

The antenna design and analysis trainer EA-818 allows the study of the Propagation Pattern and Gain of antennas which includes 10 different types of antennas.

The trainer integrates a controller unit that acts as an RF signal source of 500 MHz, 2 GHz and 10 GHz that can control the direction of the antenna. In addition, an antenna simulation software is supplied to practically reproduce the pattern and characteristics of an antenna through the PC. The antenna trainer is designed for its continuous use, thus its transport and storage are easy and can be used in narrow spaces (approx. 100 m). It allows trainees simulate real scenarios due to it consists mainly of a repeater Telecommunications antenna and a satellite dish antenna.

The EA-818 enables a high customization level of the directional and gain characteristics of the Dipole and Yagi antennas thanks to the possibility to add and move physically the elements.

and the development of skills to installing and assembling. The trainer is also prepared for the current regulations of Telecommunications Infrastructures.

The trainer is supplied with an actual installation assembled and configured.

It is composed of two modules, the emitter and the receiver. It has several types of emitters, transmission channels, receivers, modulators and demodulators, in order to configure various analog transmission systems. For instance, it permits to compare the advantages of several transmission systems over others, including those fiber-optics based, or to analyze interference phenomena between channels.

The EF-970 professional trainer is an innovative training system, designed for the learning, demonstration and experimentation with the Fibre Optics communication systems, the phenomenon related to light and the principles of transmission through Fibre Optics; as well as the latest tendencies like LASER and WDM systems.

Destinated to the theoretical-practical study of a DVD & CD player, the ED-845 allows to observe the internal composition of the mechanics, analyze the signals that take part of the operation, and to simulate several faults for the study of troubleshooting and diagnostic methods. Includes documentation (theory, practical and professor manuals), a DVD test disc, remote control and a block diagram that shows the generic structure of a player.

I believe that NetworkX is a device driver associated with the CrypKey copy protection scheme used by Protel. Check your "Devices" control panel (in the Windows control panels folder) to make sure that the NetworkX device is not set to "Disabled".John Williams

I'm testing Protel because we will perhaps buy several CAD stations.

Results so far:- Protel in't really a complete integrated suite, merely an assortment of

different

programs that use the same gui. The interface between the schematics and

the layout module is clumsy in my opinion. Forth and back annotation is

complicated compared to other ecad systems.- Protel produces sometimes protections faults. Some are reproduceable, some

not. This was a big Problem with SP1 and has gone better with SP5 but it's

still

a problem. It seems that protel catches the faults somehow, because it doesn't crash, but there are orphan processes in the task list afterwards.- Protel has memory leaks.- Some other problems that I don't remember.

Am I the only one who doesn't like protel?

The fact that they're up to service pack *5* should tell you something

about how Protel work, although I guess they're not much different to

any other software company these days. IIRC SP1 was released within days

of the original version. You're lucky they've gone to SP5 and haven't

released "Protel2000" and asked for another grand to "upgrade" to the

"new improved" which still has the same bugs as versions which are 10

years old.

What alternative is expected?Sheesh; if the list was inactive, it would be useless; it's active and

someone complains about too many messages. A dozen is too many?

Actually, there are often more than that. But you *don't* have to read

them all! I filter all my mail automatically into a folder for each

list to which I subscribe. But I do read nearly all the Protel mail: I

make my living with this software and I wouldn't pass up any of it.You should see the Accel-Protel list, formed by Accel users when

Protel acquired Accel. It quickly became a prime source of support.

Unlike Protel users, Accel users pay substantial money for support,

but there is simply no way that a company can provide support as well

as the users. The company may know how the software was designed, but

the users know how to *use* it, which may or may not be the way it was

designed.By the way, Protel management and employees also read the list, we are

informed. They've been quite responsive since the list became

pro-active instead of being just an extended gripe session. The result

is that there is much less to gripe about.Anyway, this list is *the* place to ask Protel questions. There are

well over a thousand Protel users subscribed -- I haven't seen the

numbers lately --, and questions get answered quickly.Abd ulRahman Lomax

It has become one-button (with the Synchronizer), but Protel still

supports the net-list, was-is list form of communication. Protel does

give you much more control over the interface; to some people that

might seem clumsy, but once you know the settings you want, you can

forget about it. Many users continued to use the old way, not

realizing the new features. I was one of them, until I saw the

Synchronizer in use at PCB Design Conference West.When Protel communicates schematic changes to a PCB, a list of

"macros" is created; the actual changes are accomplished from this

list. There are other CAD systems out there which are not so polite,

as I learned to my chagrin when what was supposed to be a minor change

ate all my footprints because they were not correct in the schematic,

and there was no warning that they would all be replaced.Protel gives you the choice: you can accept the existing footprints,

or update them, or you can selectively accept or update.

Protel does note that the recommended operating system is NT. Users

have also reported good results with W2000. Protel does work with W98,

but it is a resource hog and most crashes appear to result from

running out of resources. If you must use W98, and especially if you

run other applications at the same time, use a resource meter and if

resources get low, shut down other apps or shut down Protel and start

over. The Design Rule dialog boxes are famous for taking great gulps

of the limited resource memory.Actually, however, I'm running W98 and have had no problems since I

stopped running Norton Utilities in the background. The bad news? I'm

no longer running CrashGuard. The good news? I don't seem to need it

any more.

No, you're just in the minority. Protel seems to be, in the U.S.,

where it got off to a bad start with the Accel/Tango fiasco, quitely

becoming the majority CAD system in terms of numbers of companies.

It's not the majority in terms of numbers of seats; that would be, I

would think, Cadence Allegro. In the U.S. Protel is very strong in

other countries, I think.Yes, it's got problems. But so does every other CAD system I know. You

can easily pay five times as much for problems just as irritating.PADS was just giving away licenses to attempt to attract Protel and

Accel PCAD users. Seriously, the licenses were free, all you had to do

was pay for one year's support. It was too good an offer to pass up;

as a service bureau it is very useful to be familiar with and able to

interface with other CAD systems. And Protel just came out with

translators for PCAD and PADS. So I now have a PCAD seat, courtesy of

a client, and a PADS seat, courtesy of PADS' desperation. Ah, yes,

they aren't PADS any more, they were just eaten by Innoveda.It's a bit ironic, seeing how they advertised the Protel/Accel offer,

trying to stir up anxiety about the future, especially among Accel

users. But what has *actually* happened is that Protel USA is moving

to San Diego; the Accel facility is becoming the U.S. hub for Protel.But as I noted on the Protel list, where Protel is location makes very

little difference, since the best source of support is the user group

list. I've never called the Protel office for support, though I have

made bug reports when I was a beta site for Protel 99SE.
