Local Area Network Trainer (Model : XPO-LAN)

Introducing XPO-LAN, a compact LAN experiment setup with four nodes showcasing various physical topologies like Token Ring, Token Bus, Ethernet (CSMA/CD), and Modbus. Explore protocols such as TCP, IP, HTTP, FTP, SMTP, and Wireless LAN (802.11).XPO-LAN includes error generation features via Network Protocol Analyzer Software, demonstrating protocol nuances. For undergraduates, free JAVA programs enable hands-on socket programming experience with TCP/IP, UDP, etc., within the lab LAN. The tabletop setup, designed on a light and sturdy Aluminium profile (4X2) rack, comes complete with cables and connectors. An optional USB to RS232 converter enhances connectivity. Each unit is accompanied by a user guide for easy comprehension.
