Network ConfigurationThis.page.allows.you.to.configure.the.various.
aspects.of.the.IP.port.and.its.relationship.
with.the.local.network.
��
MAC Address
Media.Access.Control.address.–.this.is.the.unique.and.unchangeable.code.that.
was.hard.coded.within.your.AdderView.CATxIP.1000.unit.when.it.was.built..It.
consists.of.six.2-digit.hexadecimal.(base.16).numbers.separated.by.colons..A.
section.of.the.MAC.address.identifies..the.manufacturer,.while.the.remainder.is.
effectively.the.unique.electronic.serial.number.of.your.particular.unit...
Use DHCP
DHCP.stands.for.‘Dynamic.Host.Configuration.Protocol’..Its.function.is.
particularly.useful.when.connecting.to.medium.size.or.larger.networks,.such.
as.the.Internet..When.this.option.is.selected,.your.AdderView.CATxIP.1000.will.
attempt.to.locate.a.DHCP.server.on.the.network..If.such.a.server.is.located,.it.
will.supply.three.things.to.the.AdderView.CATxIP.1000:.an.IP.address,.an.IP.
network.mask.(also.known.as.a.Subnet.mask).and.a.Gateway.address..These.
are.not.usually.granted.permanently,.but.on.a.‘lease’.basis.for.a.fixed.amount.
of.time.or.for.as.long.as.the.AdderView.CATxIP.1000.remains.connected.and.
switched.on..Discover allocations.
IP Address
This.is.the.identity.of.the.AdderView.CATxIP.1000.within.a.network..The.IP.
address.can.be.thought.of.as.the.telephone.number.of.the.AdderView.CATxIP.
1000..Unlike.the.MAC.address,.the.IP.address.can.be.altered.to.suit.the.network.
to.which.it.is.connected..It.can.either.be.entered.manually.or.configured.
automatically.using.the.DHCP.option..When.the.DHCP.option.is.enabled,.this.
entry.is.unavailable..See.IP addresses.
To get here
1. From.a.local.keyboard,.log.on.as.the.
‘admin’.user.
2. Press. . ..(hotkeys.can.change).
3. Press. .to.show.the.Main.Menu.
4. Select.‘Configuration’.and.press. ..
5. Select.‘Network.Configuration’.&.press. .
Net Mask
Also.often.called.the.‘subnet-mask’,.this.value.is.used.alongside.the.IP.address.
to.help.define.a.smaller.collection.(or.subnet).of.devices.on.a.network..In.this.
way.a.distinction.is.made.between.locally.connected.devices.and.ones.that.are.
reachable.elsewhere,.such.as.on.the.wider.Internet..This.process.helps.to.reduce.
overall.traffic.on.the.network.and.hence.speed.up.connections.in.general..See.
Net masks.
Gateway
This.is.the.address.of.the.device.that.links.the.local.network.(to.which.the.
AdderView.CATxIP.1000.is.connected).to.another.network.such.as.the.Internet..
Usually.this.is.a.network.switch.or.router.and.it.will.be.used.whenever.a.device.
to.be.contacted.lies.outside.the.local.network...
VNC Port
This.is.the.logical.link.through.which.communications.with.a.remote.VNC.viewer.
will.be.channelled.(see.What is a port?)..The.default.setting.is.5900.which.is.
a.widely.recognised.port.number.for.use.by.VNC.software..However,.in.certain.
circumstances.it.may.be.advantageous.to.alter.this.number.-.see.Security issues
with ports.for.more.details..
Note: The VNC port and HTTP port can be set to the same port number in order
to simplify router and firewall configuration. If this is done then the AdderView
CATxIP 1000 will “listen” for both types of traffic on the single port.
HTTP Port
This.is.the.logical.link.through.which.communications.with.a.remote.web.
browser.will.be.channelled..The.default.setting.of.80.is.an.established.standard.
for.web.(HTTP.–.HyperText.Transfer.Protocol).traffic.though.this.can.be.changed.
to.suit.your.local.network.requirements.
Clear IP Access Control
This.option.removes.all.entries.from.the.IP.access.control.feature.within.the.
AdderView.CATxIP.1000..The.IP.access.control.feature.(configurable.by.a.global.
admin.user).allows.certain.network.address.ranges.to.be.denied.access.to.the.
AdderView.CATxIP.1000..If.set.incorrectly,.it.is.possible.to.exclude.all.network.
users.and.so.this.option.provides.an.emergency.recovery.point...
