Serial version: no connection at all

Post by joho500 »

Hi all,

I've purchased the serial version of the gateway. First connected the serial interface connector of the gateway directly to the serial interface of the PC running Ubuntu Server. No respons. Then I purchased a serial extension cable (male-female) and still no respons. I think syslog should show some message, right? I tried connecting the power first and then the serial cable and the other way around. Am I doing something wrong? Probably something stupid... :oops:

Thanks in advance.

Connecting a device to a serial port doesn't normally result in messages in syslog.

I suggest you go through the troubleshooting procedures (updated today!) to see if you get any messages from the gateway.

Have you directly connected to the serial interface to see if anything happens there?

For example use minicom:

Code: Select all

sudo minicom -s
Select "Serial port setup"
Set option A (Serial Device) to you serial device (something like /dev/tty... )
Set option E (Bps/Par/Bits) to 9600 8N1

Then hit [ENTER] to return to the main menu and choose Exit. This will make you exit the setup invoked by the "-s" option and start the communication according to the parameters you just entered.

Now you should be able to enter:

Code: Select all

PR=A
And the gateway should respond with version information.
