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. The default setting is
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. The default setting is 600.

Monitor Mode at Bootup

This option allows you to disable all entries into Monitor Mode during startup, except for
the 'xxx' sequence. This prevents entry using yyy, zzz, xx1, and yy1 key sequences
(only during the bootup sequence). The default for Monitor Mode at bootup is N (No).
