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
Use the serial port to configure the gauge's IP Address, Default Gateway, and Subnet mask. Contact your network administrator for the appropriate settings.
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.
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.
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.
UDP commands are received on port 1001, and responses to commands are transmitted from port 1001. All
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.
