TCP Keepalive time in seconds

This option allows you to change how many seconds the unit waits during a silent
connection before attempting to see if the currently connected network device is still
on the network. If the unit gets no response, it drops that connection.
TCP Keepalive time in s (1s – 65s; 0s=disable): (45)? _

ARP Cache timeout in seconds

Whenever the unit communicates with another device on the network, it adds an
entry into its ARP table. The ARP Cache timeout option allows you to define how
many seconds (1-600) the unit will wait before timing out this table.
ARP Cache timeout in s (1s – 65s; 0s=disable): (600)? _
