7. Edit the Ping Information

of the line to a specifically addressed remote unit over
the ethernet. Receipt of a response validates the IP
addresses at both ends and indicates that the remote unit
is operating.

rent ping field values will be displayed. The prompt
line at the bottom of the screen lists the hot keys for
each field. (Fig. 15) The field meanings are given in
Table G.

Timer settings allow you to balance network traffic
load vs. alarm response times.

from the E)dit menu.
b. Type in C to change the cycle time, T to change the
try time or F to change the fail time. (See Table H
for a description of each field.)
Note: The smaller the CYCLE number, the sooner
you will find out about failures, but low numbers
also increase the traffic on your LAN.
c. Press <Enter>.
d. When you have changed all fields that need changing,
press the escape key <Esc> twice to return to the
system submenu.
Note: The FAIL time should be set to several times
the CYCLE time to allow multiple PINGs before a
