(1) First of all, please make sure that the network connection between the terminal and the Host PC is working. A terminal can be connected directly to the Host by an Ethernet cable, if their IP addresses are in the same range. (If the terminal and the Host are not in the same IP address range, the Host will not be shown in the Host List detected by the terminal. In this case, you need to specify the IP address of Host in the Setting Up page of the terminal. )
(2) Please check if the Ethernet cable connected to the terminal is OK. When the connection is OK, the power light of the terminal will stay constant lit. If the light flashes, it means the cable connection is not OK. Then, please check the cable and connection till the light stays constant lit.
(3) Please check if the IP address of the terminal is properly configured. In default, the IP address of terminal is set to be dynamic from DHCP server. If it shows that IP address is not assigned, this means the terminal could not find the DHCP server. In this case, you need to assign manually static IP address to the terminal within the same IP range of Host PC. And make sure that the IP address has not been taken by other PC or terminal.
(4) Please check if the NetPoint Management Center is running normal on the Host PC. This program will start automatically when the Host PC has been powered up. It will prompt up a window which can be minimized to the right of Task Bar. If this program is not running, this means npsgr.exe is missing. You need to re-install NetPoint.
