and IP Address.
PINGER IP SETUP SCREEN
The IP address for the Pinger is input from this screen. The Pinger
comes programmed with a default address of 192.168.42.1. The Pinger
IP address is changed as described in the Data Entry section.
POWER DOWN SETUP SCREEN
The Pinger will automatically turn off after the time selected in the
Power Down Setup screen.
Settings available are five minutes, fifteen minutes, thirty minutes and on
(must be turned off manually). Press the SAVE function key to store the
selected setting.
SUBNET MASK SETUP SCREEN
To Ping an IP address in a subnet different than the subnet of the
Pinger, requires that the Subnet Mask be entered and “ON” and the
appropriate Gateway IP address has been entered. Mask “ON” and
OFF” is selected with the Up/Down Cursor key. The Mask is entered
as described in the Data Entry section. A zero in the first field is an
invalid mask entry and the Pinger defaults to 255 when the mask is
saved.
NOTE: Subnet Mask and Default Gateway IP address may be found by
going to a computer on the subnet where the Pinger will be used, open
the Windows Control Panel, open the network icon, open the LAN Icon,
select TCP/IP Protocol and then select properties.
GATEWAY SETUP SCREEN
The IP address for the default Gateway (typically a router or a
server) is input from this screen.
Pinger MAC SCREEN
The Pinger MAC address is displayed in this screen. The MAC for
each Pinger is unique and can not be changed. See Note in DHCP.
