TP Cable Termination for Ethernet Communication

It is vital that your Ethernet cable be the correct cable type and that it be properly terminated
with the correct pinout. Ethernet links use Category (CAT) 3, 5e, or CAT 6, unshielded
twisted pair (UTP) or shielded twisted pair (STP) cables, terminated with RJ-45 connectors.
Ethernet cables are limited to a length of 328 feet (100 meters).
The cable can be terminated as either a patch cable or a crossover cable (see figure 5) and
must be properly terminated for the application:

USB Ext port — Connect the Annotator 401 to an USB Extender Receiver via a
shielded twisted pair (STP) cable.
Pair button and status LED — Press the button to pair the Annotator with a USB
Extender Receiver (see Pairing/Tying the Annotator 401 to the USB Maxtrix
Controller on page 11).
Reset button and status LED — This recessed button initiates three levels of reset on
the Annotator. To initiate the different reset levels, use a pointed object such as a small
Phillips screwdriver or stylus to press and hold the button while the switcher is running
or while it is being powered up (see
LAN (Ethernet) port — Plug a network cable into this port to connect the unit
to a network (via a switch, hub, or router) or to a single computer (see

Remote RS-232 port — Connect a host device, such as a computer or control
system, to switcher via this 3-pole captive screw connector for serial RS-232 control
