Off-air-decoder input into PDW - RS232 Help please
« on: 05 Jul 2013, 05:30:09 »
Hi Team,

Wondering if you are able to supply some details to me regarding PDW RS232. We have been using PDW as a source of paging information for years via a scanner and disc tap.

We want to migrate to using an Off-Air-Decoder (PDT-2000) with a serial output to input into PDW so we can use its alerting features.

Below I have pasted what I can have as a input string into PDW from the OAD. I have also attached the user documentation if you require it.

I need to know (if you are willing to help) what items in what order are required for PDW to understand the PDTs output over the serial bus.

The items which are options are below, I have has many guesses but I still am unable to get it working.


\r\n ----- new line

%n or %N ----- name of address

%a ----- address in decimal

%c ----- address in 7-digit decimal(If address is larger than 7-digit, it
will be cut to 7-digit. If it is less than 7 digits, zero will be padded)

%A ----- address in hexadecimal

%p ----- protocol

%m ----- message type

%b ----- baud rate in 4-digit decimal, i.e. 0512

%B ----- baud rate in hexadecimal

%l ----- numeric level, i.e. 0-3

%L ----- alpha level, i.e. A-D

%t ----- 24 hour with second

%T ----- 24 hour time

%s ----- 12 hour with second

%h ----- 12 hour time

%d ----- day

%M ----- month

%y ----- year

%Y ----- day/month/year

%U ----- month/day/year

%I ----- year/month/day

For example: \r\n Name:%n Capcode:%a Protocol:%p Time:%T Date:%Y \r\n


Cheers,
Josh

The serial input for PDW is a 19200 bit/s stream. It expects the raw POCSAG/FLEX/Mobitex-bits, sliced into chunks of 8 bits and with added start and stop bits to comply with the RS232 standard.

Also see http://www.discriminator.nl/rs232/index-en.html - 'How does the interface work?'

What would be the added value of the Off-Air-Decoder?

Regards,
Rene

That's unfortunate  :(

Would have been good to work on this one together since the hardware we are using is quite powerful so would be good to use with PDW

Hi guys, sorry - I have had no advances on this at all! Have you have any luck upton?

I have contacted the vendor of the PDT to no avail.

Thanks
