NPort 5000 Series User Manual
Accessible IP Settings allow you to add or block remote host IP addresses to prevent unauthorized
access. Access to the NPort is controlled by an IP address. That is, if a host’s IP address is in the accessible
IP table, then the host will be allowed to access the NPort. Three setting types are described below:
• Activate the Accessible IP list
Operation modes are NOT allowed for IPs NOT on the list. IPs that are not on the list will not be granted
when communicating with NPort via Operation mode
• Apply additional restrictions
All device services are NOT allowed for IPs NOT on the list. Services will not be granted for IPs that are
not on the list. Please note that all IPs will still have access if the IP list is empty, even though the
function is enabled.
Tip: For exact IP identification, the netmask needs to be 255.255.255.255.
• Only one host with a specific IP address can access the NPort
Enter “[IP address]/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).
• Hosts on a specific subnet can access the NPort
Enter “[IP address]/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
• Any host can access the NPort
Disable this function. Refer to the following table for more details about the configuration.

Firmware Upgrading Compatibility Check
At times, Moxa needs to change the components within the NPort, which means the driver in the firmware
needs to be updated. However, the firmware cannot always contain all the versions of driver in one file;
therefore, in some occasions we need to separate the firmware for the older and newer versions of
hardware. Before you decide to update the firmware to a newer or older version, please make sure that the
firmware is compatible with your NPort hardware version. In most of the cases, if a firmware does not
specify for particular hardware version, it is supposed to support all models in the series and for any
hardware revision. If you are not sure, please refer the product website to check for instructions or refer to
the table below for specific cases, or otherwise, please consult your region’s technical support for
confirmation.
