Scanners and receivers / encryption code on Resq

« Last post by ukh on 16 Mar 2023, 10:41:32 »

Is it possible to read the encryption code on a swissphone resq if you have the actual installation file for the pager. I think the code is somewhere in the file??
Regards Ulrik

PDW Support (other languages) / German Language character Set

« Last post by trax04 on 09 Sep 2022, 10:42:54 »

Hat jemand das Character Set für die deutsche Sprache inkl. Umlauten.
ich habe bis dato noch nicht verstanden, welche Zeichen wie ersetzt werden müssen.

Danke für eure hilfe.

PDW Support / Language.df table / How do I add custom characters?

« Last post by Clerco15 on 21 Aug 2022, 14:03:28 »

In the language.df file it says you can add more languages on your own.

I've tried adding letters ?šž for Slovene (both lower and upper case) and I selected them in Character Set option but decoded messages containing those letters still replace them with a symbol.

That's how I added them


That's how it comes out (this particular word is poŽar so uppercase Ž which get's replaced with @)


Font is Courier New and I also installed the font on my system. I've tried it on both versions, v3.2b and v3.12 and get the same result.

PDW Support / VAC mapping

« Last post by pnoelw on 03 Jun 2022, 19:06:45 »

Until recently, I had 10 VAC's enabled and had been running 3 instances of PDW on cables 7-9. I recently increased to 20 VAC cables and have been using most of these succesfully with other software (ALE, HFDL, etc).

Today I ran PDW again and couldn't get any signal through on the same 7 to 9 cables. After running through all 20 I eventually found that the cable mapping in PDW has got mixed up so
VAC line 7 comes in on the PDW dropdown under 13. Line 20
VAC line 8 > PDW 14. Line 4
VAC line 9 > PDW 3. Line 3

I'm sure there's a perfectly logical reason but is there a solution?

Regards
Noel.

Is it possible to change the frequency on a Swissphone DE925?? and how to do it. Or not ;-)

Data Slicers and Interfaces / Re: FSK to USB interface

Thanks for the reply Rene.  I found an interesting site that make reference to settings for working with FTDi chips.  It makes an interesting suggestion about advanced settings of your com port when using FTDI chips. https://www.digi.com/support/knowledge-base/optimizing-usb-to-serial-port-settings.  The standard 9600 bit per second is shown however there is a vast difference in the receive bytes, transmit bytes and latency speed settingsin advanced settings.  I am trying these at the moment and a noticeable difference in regards to "cleaner" messages being displayed, that is not as many garbles which sometimes appear.

Normally, you shouldn't have to worry about the COM port settings, but the speed to the PC is 19200 8N1 as well.

You can use a serial port monitoring program to see the data sent to the PC.

Data Slicers and Interfaces / FSK to USB interface

« Last post by orion_jb2001 on 05 Feb 2022, 23:12:36 »

Just a question on the USB connection interface.  In the very good description suppplied:
##The incoming signal is sampled with 5 times the data rate. So e.g. a FLEX-1600 signal is sampled 8000 times per second

The transitions from 0 to 1 and from 1 to 0 are used for bit synchronisation. Ideally, when receiving data, these 5 samples will be 11111 or 00000. If the 5 samples received are e.g. 11110 or 10000, resynchronisation needs to take place: one sample to the right resp. one sample to the left

The majority of the 5 samples determines whether a 0 or 1 bit has been received

When 8 bits have been received, these are sent to the USB module observing the standard RS232 protocol with 19200 bit/s , 8N1 (8 data bits, no parity bit, 1 stop bit)##

A great description of what happens with signal to the USB module, but what about from the USB module to your PC/laptop?  Relating to the reference in bold, the RS232 protocols, it mentions 19200 bits, is that what you should have your com port to the computer set at or what should your relevant com port be set to, for connection to you PC?
