A user transaction system can be viewed from an REMCS port and a certified
service engineer port.
To solve these problems, VLAN functions are used in the management LAN hub.
VLAN is a function for logically dividing each port of one switching hub into groups,
each operated as an independent LAN.
The VLAN functions of the PRIMEQUEST management LAN can be used in one of
the three modes below, so that the user can select the mode that is suited to the
operation method.
The following three modes are available. The default is the VLAN mode.
