DM Agent Network Range List
Add devices to the Network Range List by specifying the IP address, host name, IP range, or simply importing the device list.
After adding the device IP Address/hostname, you can search them to check if they are discoverable.
Follow the order below to add and discover devices.

In the Network Range List screen, click the Add 
button to specify device's IP address or host name.
-
One hostname: If selected, enter the hostname of a device.
-
One IP Address: If selected, enter the IPv4 of the device.
-
Specify IP Range: If selected, enter an IP address in From and To then specify the Subnet Mask.
You also have the option to import the device range list in CSV format. Click the Import 
button to upload the file. Here is a sample import/export file format.
Line 1:"From","To","Subnet Mask"
Succeeding lines:"10.85.7.1","10.85.7.255","255.255.255.0"
Line 1 must have the text "From","To","Subnet Mask", then write the IP address range in the succeeding lines.
If you want to input one IP Address, add the following line: <IP Address>,,,
If you want to input a hostname, add the following line: <hostname>,,,
You can also download the list of IP Address ranges by clicking the Export 
button.
Check the “Trust All Certificates” to allow the DM Agent tool to bypass the certificate check and remove the security SSL/TLS that provides the encryption of data during the communication.
If you decide to uncheck this setting, ensure that the device “Permit SSL/TLS Communication Settings” is set to “Ciphertext/Clear Text”. If this setting is not possible, you must install the printer device’s certificate in the Windows CA root to the machine where the DM Agent tool is running to allow the communication.
To discover the devices, click [Search] at the bottom of the list grid.
The search will display a pop-up dialog with the number of devices that are found, not found, and not supported. All devices that were found are displayed in the list.
Devices that are 'not found' and 'not supported' are not displayed in the list. However, you can see them and the reason for the failed discovery by clicking the [Discovery Log].
The device activity log will look like this: <date and time>, <device IP address/hostname>, <action performed>, <result and reason of the discovery>
For example: 2024-05-02 12:04:03, 10.10.20.21, Device Discovery, Failed: -- init -- Device not reachable.
The example above shows that the device discovery of device 10.10.20.21 failed because the device was not reachable.
