Port Selection Menu - Seiko SMARTCS NS-2250 Instruction Manual

Note that, in Select mode, the same telnet server (TCP:23)/SSH server (TCP:22) is used
to access monitored equipment and log into the NS-2250.
In Select mode, when a normal user requests access, it is regarded as a login to the
NS-2250. When a port user requests access, it is regarded as access to monitored
equipment, and the port selection menu appears.
The user can access a serial port by selecting that serial port and the connection method
(Normal mode/Monitoring mode) in the port selection menu that appears.
