Applications
The Lanport-II was used for troubleshooting and testing 10BASE2 Thin Ethernet networks prevalent in enterprises during the 1980s-1990s. Technicians relied on devices of this type to verify network connectivity, detect cable faults, and diagnose segment issues on coaxial LAN installations. The dual serial ports enabled connection to network devices and monitoring equipment for comprehensive network analysis on legacy systems.
This Microtest Lanport-II network testing device (model 3851-02) has been inspected and appears to be in good condition. The unit shows light wear consistent with age — the case has some discoloration and minor scuffing typical of a device from 1990, but there is no cracking or significant damage visible. The BNC network connector and both DB9 serial ports (COM1 and COM2) appear intact. The original spiral-bound Lanport-II User Guide (Manual Part Number 2920-4500-01, Document Number 04-101-0990-2) is included and appears complete and legible with normal shelf wear.
