Hi all!
I have a problem with a Panasonic KX-TDA200 system.
The system is connected with a pc through the serial port. When I try to read calling infos from the port the phone system returns some invalid characters. However the output does contain some regular character repetitions.
The phone system was restarted but the problem is the same.
One output example (unsure how this will appear on the page)
ȈðzY:zHKK¼J¥ ÚRLJÈ
ȈðzY:zHK{¼JJHkz
JJ:JHJJI
zY:zHKZ¼JJHZŠLJÈ
ȈðzY:zHKJ¼JÂ
HŠJÈ
ȈðzY:zHKZ¼¥
HËâ€
HÈ
ȈðzY:zHKK¼Z
JHkZkJJ:JHJJI

It sounds like the parity or stop bits are wrong.
The tda 200 is set as
Baud rate :19200
Parity bit: None
Flow control: None
NL code : CR + LF
Word length : 8 bits
Stop bit : 1 bit
You can change this in the maintenance tool
If set up as above it should work fine

try installing a null modem adapter on cable plus make sure you have your baud rate matched with tda and other parameters set right in hyperterminal no flow control

Hi
I've tried the folowing settings:
Baud rate :9600
Parity bit: None
Flow control: None
NL code : CR + LF
Word length : 8 bits
Stop bit : 1 bit
But the output is still a mess. Can the 9600 baud setting make this difference? I guess the phone system is configured to 9600 baud since it communicates with the pc.
By maintenance tool you mean the software shipped with the phone system?
The phone system is some 50 km away from me, so I test it remotely.

i doubt you'll be able to read smdr info via modem
but i could be wrong!
Baud rate :19200
Parity bit: None
Flow control: None
NL code : CR + LF
Word length : 8 bits
Stop bit : 1 bit
IS THE DEFAULT SMDR SETTINGS

OBT and Frank_DaFoneguy were right, the 19200 baud rate setting solved the problem.
