Ethernet Port Indicators
The two LEDs on the DT80’s Ethernet port (P279) indicate the following:
• Green LED – Link OK; should come on and stay on as soon as you connect the Ethernet cable
• Amber LED – Activity; blinks every time a data packet is received
If the green LED does not come on then either the DT80 Ethernet port is not enabled, or the cable is faulty, or the socket
you are connecting to is not connected to an active Ethernet network, or the hub/bridge/router is not powered up.
The amber LED indicates communications activity anywhere on the local network – this activity is not necessarily
directed at the DT80.
Note: These LEDs will only operate if the DT80 Ethernet port is enabled. The Ethernet port will only be enabled if its IP address has
been set, or DHCP has been enabled. (See How to set up Ethernet (P235)).
MAC Address
All Ethernet devices have a globally unique 12-digit identifier programmed into them during manufacture. This is called
the MAC Address. The DT80's assigned MAC address can be viewed using the
EAA (Ethernet Adapter Address)
command, but it cannot be changed. You should not need to be concerned with this address.
Ethernet Commands
Querying Ethernet Parameters
The current Ethernet parameters can be viewed using the following commands
Command
Description
IP
Returns the DT80’s current IP address
IPSN
Returns the DT80’s current IP subnet mask
IPGW
Returns the DT80’s current IP gateway
EAA
Returns the DT80’s Ethernet network adapter MAC address
For example:
IP
192.168.42.15
IPSN
255.255.255.0
IPGW
192.168.42.3
EAA
00-90-2D-00-12-6B
In this example the DT80 has IP address 192.168.42.15, and is connected to network 192.168.42.0/24. The computer or
router at IP address 192.168.42.3 is the designated gateway for this network. Any data that needs to be sent to a
different network will be sent via this computer.
Setting Ethernet Parameters
All Ethernet parameters are set using profile settings (see Profile (P276)), i.e.
PROFILE ETHERNET key=value
The following keys are defined:
Key
Value
Default
ENABLE
Set to YES to enable the Ethernet port, NO to disable (saves power)
YES
IP_ADDRESS
IP address of DT80 Ethernet port. May be set to a static IP address, or
AUTO
(obtain an address from a DHCP server)
AUTO
SUBNET_MASK
Subnet mask for the network segment to which the DT80 is connected. This
setting will be ignored if a valid subnet mask was obtained from the DHCP server.
255.255.255.0
GATEWAY
IP address of the gateway computer/router for network segment to which the DT80
is connected. This setting will be ignored if a valid gateway address was obtained
from the DHCP server.
0.0.0.0
For example, the following commands would be used to set the parameters in the above example:
PROFILE ETHERNET IP_ADDRESS=192.168.42.15
PROFILE ETHERNET SUBNET_MASK=255.255.255.224
PROFILE ETHERNET GATEWAY=192.168.42.3
