Ethernet option.
Wiring
Configuration command to see if the gauge supports
Ethernet. If disabled, contact your Beta
LaserMike sales representative to order
the option.
Verify that the wiring matches the wiring
listed in the manual. The LS9000
Instruction Handbook revision A
contained an error in the 37-pin cable
pinout, where the Ethernet pinout was
incorrect.
Use the serial port to configure the
gauge's IP Address, Default Gateway,
and Subnet mask. Contact your network
administrator for the appropriate
settings.
How do I know if the gauge is
communicating on my network? Send a ping message The gauge will respond to ping
messages up to 64 bytes in length. If
this works, then you should be able to
use telnet to connect to the gauge.
TCP/IP connection was refused. Already connected from a
different host, or did not
close last connection
properly.
Over TCP, the gauge supports one
Telnet (port 23) connection and one
TCP (port 1003) connection. Close the
current connection before opening a
new one.
LaserTrak can't find the gauge
over Ethernet, but I can ping it and
connect with telnet. Different subnets Try setting the IP Address and subnet
mask to the same subnet. LaserTrak
searches for LaserSpeed gauges via a
UDP broadcast message. Ethernet
switches do not forward UDP
broadcasts, so LaserTrak cannot search
outside of the local subnet.
Can send UDP commands and
receive responses, but don't
receive real-time data
(TE/TB/TT/TF data). Command responses and
real-time data are
transmitted on different
ports. UDP commands are received on port
1001, and responses to commands are
transmitted from port 1001. All real-time
continuous output data is transmitted
from port 1002.
Getting CRC Errors on switch,
which leads to loss of connection Bit rate too high The gauge will first attempt to connect at
100Mbit/half duplex, and if this fails will
swtich to 10Mbit. It does not
continuously renegotiate the network
speed. 100Mbit is sometimes more
susceptible to noise and packet loss.
Configure the switch to communicate at
10Mbit/half duplex only.
