Connection is made via the Ethernet port on the front of the unit. 
If the EFX48 is remotely monitored via SNMP or web page via the Ethernet port 
ensure the network cable is restored to the unit after local work with a Laptop/PC is 
concluded. It may be a requirement to inform the operations team to advise of works 
being performed before any communication connection is removed. 
 
“Direct Mode” is used to simplify a Laptop/PC connection to the 
EFX48. This mode serves an IP address to the Laptop/PC from the 
EFX48. Once the networking cable between the EFX48 and 
Laptop/PC is removed, the EFX48 will disable “Direct Mode” and 
revert to previous “Address Type” i.e. either IPv4 or Auto. 
 
 
►  To connect to the EFX48 using a Laptop/PC 
•  Whenever a network connection is initially established – i.e. from power up and/or from 
when the network cable is inserted and the EFX48 has an “Address Type” of Auto then the 
EFX48 will expect to receive an IP address from a DHCP server. 
•  If ”Direct Mode” is selected and if there is no other DHCP server available, then the EFX48 
will supply an IP address to the Laptop/PC.   
•  Unplug any networking cable already connected to the unit. 
•  Select the following menu on the EFX48: Settings > Network > Direct Mode 
•  Press and hold the 
enter
 key. If PIN protection is configured, wait for the Pass Code page to 
appear and enter the 
Access PIN
. 
•  Navigate using either the Left or Right keys to set Direct Mode to Active. 
•  Connect a standard networking cable between the Laptop/PC and the EFX48. 
•  Use a web browser to access the URL https://192.168.1.10/. 
 
If the EFX48 has been configured for ‘standard’ (insecure) access, use ‘http’ instead of 
‘https’ in the above URL. 
 
•  When complete, remove the networking cable and restore any network cable previously 
installed. 
 
“Direct  Mode” is a temporary mode which is terminated as soon as the network link is 
broken by disconnecting the cable and cannot be permanently selected. This is to ensure 
that the DHCP server functionality of the EFX48 unit does not interfere with the 
operation of any other DHCP servers on the network.
