your thumb and forefinger. Keep the jacket clamped in this retracted
position until the fourth step.
2. Pull the twisted pairs to the one side and untwist them back to the
edge of the vinyl jacket. Smooth the kinks out slightly by pulling the
conductors through your fingers.
3. In the correct color sequence, pull one wire at a time, straight out,
clamping it in place between your thumb and forefinger. If a wire
must cross the others, make sure it does it inside the jacket. Make
sure your color sequence matches the other side and it does not
reverse. If you are rebutting a cable, verify color code. The twisted
pairs must be positioned correctly.
4. While holding the wires in the correct order, release your clamped
thumb and forefinger enough to allow the retracted jacket to slip
back. You still need to maintain enough pressure on your thumb and
forefinger to hold the jacket and wires flat but the individual wires
should stay in the correct order without holding them with your other
hand.
5. Cut the exposed wires to the correct length and slip them into the
RJ-45 connector as you release your clamped thumb and forefinger.
Crimp and test the cable.
6. Care must be exercised that the shield is not left pulled back inside
the wire jacket. We also recommend that the drain wire is soldered
to the side of a shielded style connector. Our tests show that a drain
wire that is only crimped and not soldered will make an intermittent
connection at best.
WIRING THE MATRIX TO A COMPUTER
WIRING FOR SERIAL CONNECTION
The serial connection to a PC is provided by the DB-9F connector
labeled “RS-232” on the rear of an Eclipse Omega or Median matrix, or
the DB-9F connector labeled “PC” on the front of an Eclipse-32 matrix,
or the 3.5mm jack socket labelled “RS-232” on the front of an Eclipse
PiCo.
Note: Shielded cable should be used.
The PC runs the Eclipse Configuration System (ECS) program. To
configure the serial port, refer to the Eclipse Configuration System
Instruction Manual (part 810299Z).
To connect a computer to the matrix, run cable from the matrix’s serial
connector to the computer’s serial port. The maximum recommended
length of the cable is approximately 10 feet (3 meters).
A computer has either a 9-pin serial port or a 25-pin serial port. Figure
4-1 shows the wiring for a 25-pin port. Figure 4-2 shows the wiring for
a 9-pin port.
