The Host Name is used to access and setup the VBB-NRI using Dynamic DNS in conjunction with DHCP. Consult
with network technicians for details on setting up your network in this manner.
DHCP - This setting sets up the VBB-NRI to use a DHCP server on your network (use only if you have a DHCP
server on the network).
Static - This setting forces the VBB-NRI to use a static IP address.
IP Address
â–ª When in Static mode, this is where you set the NRI's IP address.
â–ª When in DHCP mode, displays the IP address configured by the DHCP server.
Subnet Mask
â–ª When in Static mode, this is where you set the NRI's subnet mask.
â–ª When in DHCP mode, displays the subnet mask configured by the DHCP server.
Default Gateway
â–ª When in Static mode, this is where you set the default gateway.
â–ª When in DHCP mode, displays the default gateway configured by the DHCP server.
Obtain DNS Server Address Automatically - When chosen, your DHCP server will assign your DNS Server
IP addresses.
Manually Configure DNS Server Address - When chosen you will assign your DNS server IP addresses.
Primary DNS
â–ª When Automatically obtained, displays the Primary DNS chosen by the DHCP server.
â–ª When Manually entered, this is where you enter the Primary DNS address.
Secondary DNS
â–ª When Automatically obtained, displays the Secondary DNS chosen by the DHCP server.
â–ª When Manually entered, this is where you enter the Secondary DNS address.
Enable Ether Link Auto Negotiation - The VBB-NRI is capable of communication speeds of either 10 or 100
Base-T and, with this option enabled, can switch between the two speeds if necessary. Enabled this option to
allow the VBB-NRI to automatically detect and use the communication speed of the switch it is connected to.
NRI Lock (Relay 1) Configuration - This section is used to define the state of Relay 1 on the VBB-NRI in
case of network communication failure during MRO Override state or power restored without network
communications restoration.
Note: Whether the lock connected to the VBB-NRI is Fail Safe or Fail Secure will ultimately determine what effect
the state of Relay 1 will have on the lock. The examples below are assuming a Fail Secure installation.
â–ª Comm Failure - Choose one of the options to define the behaviour of Relay 1 in the event of
communication failure. Once communication is returned Relay 1 will resume its Normal Operation state.
â–ª Retain State - The lock will stay in whatever state it was in (activated or deactivated) when
communication was lost.
â–ª Unlocked - The relay will be activated when communication is lost. In most installations this will mean
that the door will become unsecured.
