Advanced Troubleshooting - Datavideo KMU-300 Instruction Manual

 DHCP：Disable
 Static IP：X.X.X.Y；the first three decimal numbers must be the same as your router or
switch. The number Y must be a number not used by any devices connected to the
network.
 Subnet Mask：255.255.255.0
 Default Gateway：Z.Z.Z.Z；same as the gateway IP of your router or switch.
Note: Some router may require special gateway IP setting; instead of the standard
192.168.1.1. Therefore, you should check the network properties on the PC before
switching to the fixed IP mode.
For example, some routers have a gateway IP of 192.168.1.254 and as a result, the default
gateway and primary DNS fields on the NVS-31 MARK IV must also be configured to
192.168.1.254.
 Primary DNS: Same as the default gateway IP, which, if causing issues, can be changed to
8.8.8.8 or 8.8.8.4 (Public DNS provided by Google).
 Click the "Apply" button to save the network settings.
 Reconnect the PC and the NVS-31 MARK IV to the network.
 Restore the PC's original network settings.
 Shut down the KMU-300; wait for approximately five seconds before turning the KMU-
300 back ON.
 You should be able to access the NVS-31 MARK IV through the fixed IP address.

Advanced Troubleshooting

If you still are unable to connect, please try the following:
 Use the ARP table to search for the encoder's MAC address; the device's MAC address is
on the print label at the bottom of your HS device.
 MAC address starts with 00:07:36:03:xx:xx.
-
Device's MAC address starts with 00:07:36:07:xx:xx (KMU-300 and KMU-300 only)
 On the command prompt (terminal on MAC OS), enter "arp -a" then press enter key to
display an ARP list. See if the NVS-31 MARK IV is successfully connected to the network.
 Execute services.msc，and on the right column of the "Services" window, locate "DHCP
Client" then click "Restart".
