If you need to enter a port numberUsually,.when.you.make.a.network.connection.to.the.AdderView.CATx.IP.(either.using.the.VNC.viewer.or.a.Web.browser).you.simply.enter.the.IP.address,.i.e..192.168.0.3..However,.if.a.special.configuration.is.necessary,.then.you.may.be.asked.to.specify.a.port.number.as.well.as.the.IP.address.What is a port?To enter a port number in a Web browser1. Enter.the.required.IP.address.in.the.usual.Address.box,..i.e..http://192.168.0.32. At.the.end.of.the.IP.address,.add.a.single.colon.(:).and.then.enter.the.port.number.(in.this.example,.the.required.port.number.is.8000),.i.e..http://192.168.0.3:80003. Continue.with.the.standard.Web browser instructions..To enter a port number in VNC viewer1. Enter.the.required.IP.address.in.the.usual.‘Server’.box,..i.e..http://192.168.0.32. At.the.end.of.the.IP.address,.add.two.colons.(::).and.then.enter.the.port.number.(in.this.example,.the.required.port.number.is.8000),.i.e..http://192.168.0.3::80003. Continue.with.the.standard.VNC viewer instructions.Access via dial up (modem or ISDN) linkWhen.you.gain.access.via.modem.or.ISDN.link,.the.AdderView.CATx.IP.uses.standard.network.protocols.to.create.a.private.two-device.network..This.approach.ensures.consistency.and.allows.you.to.use.exactly.the.same.VNC.viewer.or.browser.to.view.the.host.computers..This.is.achieved.using.PPP.(Point.to.Point.Protocol).and.means.that.you.need.to.use.a.dial-up.networking.method.to.initiate.the.connection..Such.software.is.standard.with.operating.systems.such.as.Windows,.Linux.and.Mac.OS.To initiate a dial up link1. Using.a.system.that.has.a.modem.or.ISDN.adapter.installed,.locate.the.dial-up.networking.option.on.your.system..Please.refer.to.your.system.documentation.for.more.information...2. Using.the.dial-up.networking.option,.enter.the.telephone/ISDN.number.where.the.AdderView.CATx.IP.can.be.contacted.3. Initiate.the.call.and.when.the.link.is.made,.continue.with.either.the.standard.VNC viewer.or.browser connection..Note: For the viewer network connection address, you must use the IPaddress that the admin user has set as the Server address (or PPP server IPaddress) within the Modem configuration screen.
