Fortunately, your unit provides a way for you to make the two signals occur at the
same time on the selected image. The adjustment range provides both positive and
negative levels of delay with 0 being the default.
9.3.5 Still Image Store / Testcard Source Menu Items
This item is only available for units supporting Still Image Stores (SIS) or Testcards
(TC) – which are the same thing, but may be named differently depending on your
unit.
Used to select the image from memory to use as a source for the SIS / TC source
currently selected. Dedicated software can be used to upload user-defined images
– see our website.

Items associated with the Adjust ethernet group
(Please note that not all units have this sub-menu.)
Your unit can be remotely controlled via its RS-232 serial port, but some units can
also be controlled via a Local Area Network using the Ethernet connector. This
provides TCP/IP communications to and from the unit using a custom protocol.
In most networks, all computers and other electronic equipment will have a
dedicated connection to a network hub or switch, with each item having its own ‘IP
address’ (Internet Protocol address). This is the unique set of numbers that
identifies the item on the network.
The network itself is usually segmented into a number of sub-networks. Small
offices will generally just use one sub-network, with larger ones running many sub-
networks that are linked together across a sub-network bridge. Sub-networks are
split up by assigning different ranges of IP addresses to the different sub-networks.
The ranges are defined by the ‘sub-net mask’.
In very simple setups with 2 pieces of equipment (e.g. a computer and one other
piece of equipment), it is possible to link the two together using just a cable (which
must be a cross-over cable). However, this setup is rare.
Where only a single sub-network exists (as in the majority of cases) it is vital that:
1. All equipment has different IP addresses.
2. All IP addresses are part of the same sub-net.
3. All equipment has the same sub-net mask.
In most situations the computer will already be attached to a network, and therefore
its IP address and sub-net mask will be easily accessible (e.g. in Windows XP you
