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.
If the DATA OUT port produces a large quantity of characters, it may
be sending GCF data. Try typing
forcegetty
repeatedly. If the DCM is running the gcf_out service on this port, it
will stop transmitting and give you access to the login prompt.
If the DATA OUT port is not responding at all, check the power supply
to the DCM.
I cannot see the DCM's Web site over HTTP or HTTPS.
There is a problem with the network setup. Connect to the DCM's
DATA OUT port using a terminal program and change the network
settings to suit your network. In particular:
•
If the DCM has a static IP address, use ifconfig to verify that
the DCM is using the correct IP address. If it is not, change it
with
gcfgdbset net.eth.0 static
gcfgdbset net.eth.0.netmask 255.255.255.0
gcfgdbset net.eth.0.address 192.168.0.2
(replacing 192.168.0.2 with the IP address you want the DCM
to use.)
•
If the DCM is using DHCP, use ifconfig to verify that the
DCM is using the IP address you expected. If it is not, change
the settings of your DHCP server or connect to the correct IP
address for the DCM
•
Check that your local PC can route to the DCM's IP address. For
example, if you are using a cross-over Ethernet cable, the two
hosts must share a subnet.
