How To Connect Remotely Via An Ipv4 Address - B&K 2245 User Manual

✐ Note:
Remote connection is optional. In other words, you do not need to be able to connect to your instrument
l
remotely in order to use it with the mobile and PC apps.
Please refer to the manufacturer of your router or to your Internet service provider (ISP) for information spe-
l
cific to your network.
The instrument must be on and connected to the network in order to access it remotely using the mobile or PC
l
app.
Before you begin, you will need some information about your Internet service:
Is your IP address IPv4 or IPv6 or both?
l
The instrument supports both. The difference is that IPv4 requires port forwarding while IPv6 does not.
If you have an IPv4 address, is it static or dynamic?
l
You can use either static or dynamic addresses. However, dynamic IPv4 addresses change, which requires you to
enter a new IP address in the mobile or PC app every time the address changes.
If you have a dynamic IPv4 address, can you get a static IP address or set up a DynDNS (dynamic domain name
l
system)?
You can use a static IP address or set up DynDNS, which works by assigning a persistent host name to the instru-
ment, to overcome the problem of changing IPv4 addresses.
Is your ISP blocking any instrument ports?
l
✐ Note: The instrument uses ports 80, 443 and 8700 to 8720. It is not possible to change these ports. There-
fore, remote connection is not possible if your ISP blocks any of those ports.
What you will need:
An instrument that is connected to the network (either by Wi-Fi® or Ethernet)
l
Access to the settings interface of your network router
l

How to Connect Remotely via an IPv4 Address

Use the NAT (network address translation) capabilities of your router to forward the ports of your instrument so that
you can connect to it remotely.
A general procedure is as follows:
✐ Note: This procedure applies to static IPv4 addresses and dynamic IPv4 address using DynDNS.
1. Look for the port forwarding option on your router.
If you do not find it right away, look for advanced options.
2. Create port-forwarding rules.
Port-forwarding rules link the IP address of the instrument to ports that it uses so that when you send a request
to the instrument's network from another network, the router knows to which device to direct the request.
