The web interface via port 80 supports up to eight connections to the unit. For details as to how
to access, operate and configure the unit using the web interface, refer to the KLR User Manual.

USING PORT 5024 (TELNET)
To access the unit via Telnet port 5024 the proper command line is TELENET IP ADDRESS
