Operator's guide

You can now enable the AutoDRM system under Data transfer—AutoDRM.Click Save changes to start the service.

To test the AutoDRM system, send the following e-mail to the DCM:

From: your@e-mail.address

To: autodrm@your.DCM

BEGIN GSE2.0

MSG_TYPE request

MSG_ID unique-identifier

HELP

EMAIL your@e-mail.address

STOP

where your@e-mail.address is the e-mail address to send the return message and unique-identifier is a string which you can use to identify your request. autodrm@your.DCM should be replaced with an e-mail address which will be delivered to the autodrm mailbox on the DCM.

The DCM should send a mail back to you containing help on the commands you can give the AutoDRM.

3.5 Troubleshooting DCM installations

I cannot connect to the DCM's DATA OUT port using a terminal program.

Press ENTER a few times to initiate communication.

If the DATA OUT port gives a login prompt, you should log in with your username and password. If you have not been given a different username and password, try logging in as root with the password rootme. You should change this password as soon as you can with the command passwd

If the DATA OUT port gives an ok prompt, the DCM is running the gcf_out service on that port and has provided you with a FORTH compatibility interface. Type

GETTY

and press ENTER to gain access to the login prompt.

If the DATA OUT port does not respond when you press ENTER, or produces garbage, check that your terminal program is using the same baud rate as the DCM. By default, the DCM uses a baud rate of 115200, with 8 data bits, no parity bit and 1 stop bit, and no flow control.
