Hello,

I need some help on setting up a PSTN connection to the DT80 for FTP download of files. Currently the DT80 is connected to a IG6000 via Serial cable 9->25pin adaptor.

HOST MODEM settings 
Dial: ETSEND=ATD RESET: init:ATB0&D2#MEM0&K3S0=1E0Q1&Y0&W0Z0 
EXT_POWER_SWITCH: MAX_CD_IDLE: 43200 
SEND_BANNER_CONNECT: YES COM_PROCESSING_TIME: 1 
PPP settings IP Address: 192.168.98.1 
Remote IP Address: 192.168.98.2 
user: TEST 
password: TEST 
FTP server settings Supported: YES 
user: TEST 
password: TEST

I have tried numerous times to dial into the modem, but on each occasion it will not connect with the error message saying that the computer you're dialing did not respond. can you give me some hints? Or have come across this problem before?

Many thanks in advance,
Jack

Good morning Jack,

The first thing to do is check that the modem connection is working correctly.
Try dialing in to the DT80 over a land line.There are a couple of traps here, avoid dialing via a PABX or digital PABX. Use a direct connection where ever possible.

Does the dataTaker respond?
If the dataTaker does not respond then you will need to look at the modem and how it is configured? I see from a previous post that you can't fix a baud rate for the IG6000. This might be causing problems.

Can the IG6000 auto baud up to the same baud rate as the DT80 host port? There are some modems that will only autobaud up to 19200. If this is the case then change the DT80 Host Port profile settings to match that of the maximum rate for the modem.

Do you have the same flow control method set on the modem and DT80?
When you can dial and see the DT80 connected then it is time to set up and test the PPP connection.

PPP is basically TCP/IP over a modem. You will need to configure the modem in the computer then set up a PPP connection using that hardware.

Cheers,
Roger

Good morning Jack,

More on the IG6000. If you don't fix the baud rate then the maximum speed the modem will autobaud to is 33,900. The highest maximum speed the DT80 and IG6000 both agree on is 19,200. Change the profile settings in the DT80 to set the host port to 19200 and reset the DT80.

You can now connect and talk to the DT80 via a direct modem connection. Now this works you can set-up and test the PPP connection.

Cheers,
Roger

PPP connections for SMSX and PSTN modems have been rectified.

Thanks Roger your help was much appreciated.

For others, the trick to get PPP connection working over Windows XP was the use of a script which is fixed according to 40898 PPP doesn't work with modems

The logger does not switch to PPP mode until it sees CLIENT (to which it responds CLIENTSERVER). However Windows only sends this for direct serial connections. For modems the connection event serves the same purpose so it doesn't send anything (just starts sending PPP packets).

WORK-AROUND: Workaround is to setup a login script (.scp file) on Windows
(Network properties Security tab) eg:

proc main
delay 5
transmit "^M^J"
delay 5
transmit "CLIENT"
waitfor "CLIENTSERVER"
endproc

Further more, Firmware 6.06 is required, as one of our DT80 did not work on Firmware 5.06

Thanks, all is fine now.
