Next,

Push

the knob to go to the data entry screen shown here:

Turn

the knob so that the word

Backspace

at the bottom of the

screen is highlighted. Now, each time you

push

the knob one

character will be deleted from the existing IP address entry.

Push

the knob repeatedly to erase the entire IP address field, or

as much as is required.
Once the field is empty,

turn

the knob to select digits (and the

delineating decimal point) to input the desired IP address. The

addresses in these fields always consist of four groups of three-

or-fewer digits with the groups separated by decimal points.

Once the IP address has been entered manually,

turn

the knob

so that the word

Save

is highlighted, then

push

the knob to

commit the address to memory. If the word

Save

is not visible,

this means that the entry has incorrect syntax and must be re-

entered. If a valid address is not entered and saved, the menu

will time out in a couple of minutes and revert to a previous

valid IP address or to:

0.0.0.0

Manual data-entry must then be repeated for the other

IP Set-

tings

fields:

Gateway

Subnet

and

DNS

. Entries in these fields will

be dictated by existing network protocols, depending on how

the server or router is configured. Your Network Administrator

should know all about this; it is not within the scope of this

manual to provide a tutorial on network setup. Sufficient to

say that DHCP operation is the preferred mode.

COMMUNICATING FROM OUTSIDE THE LOCAL NETWORK

To address your DAVID IV from outside your Local Area Net-

work (LAN), you must open a port on the network router. This

is required, for example, when your unit is being addressed and

controlled over the Internet.
To make it easy to remember, we picked a default port number

of 719, the formal model number of the DAVID IV. This may be

changed from the

IP Settings

menu, however. Your router must

be configured for ‘port forwarding,’ using Port 719 to forward

both TCP and UDP traffic to the IP address specific to the

DAVID IV.
Should you need to address two or more DAVID IV units from

outside the local network, each must be associated with its own

router port. Use the

IP Settings

menu to change default Port 719

to alternate port numbers for multiple DAVID IVs.
