VTX-WM1 Installation Guide v1.2 5

Installation

Preamble:

The process of installing web monitor cards

into VTX ampliers is straightforward. If cards

are being tted to multiple ampliers installed

in one or more equipment racks, each rack will

need to be provided with internal CAT5 wiring

and an Ethernet switch. The Installation section

of the manual describes in turn: i) tting and

testing cards in the ampliers; ii) networking

principles and iii) overall conguration.

Installing the VTX-WM1 card

1. Turn off the VTX ampliers into which

the cards are to be tted and unplug their

power cables. If the ampliers are tted in

a rack enclosure, disconnect all rear cables

from one amplier at a time, and remove

it from the rack. Place the amplier on a

at surface.

2. Remove the amplier’s top panel. Retain the

screws (eleven) and the transformer bolt.

3. Locate the rear panel blanking plate, undo

the two screws securing it and remove

the plate. Retain the screws.

4. On the amplier’s upper rear PCB

(Remote Vol PCB, PC331012), locate the

jumpers J109, J209, J309, J409, J110, J210,

J310 and J410. All of these (total 8) should

be removed. (Refer to pages12 &13 of the

amplier manual for full details of amplier

jumper locations.)

Remove these jumpers

5. Plug in the four screened cables

terminating in 4-pin connectors as follows:

6. Connect all the ying leads before locating

the card in place. First, plug the two

7-way ribbon cables (from J805A and

J806A on the VTX-WM1 card) to J805B

and J806B respectively on the amplier’s

main (lower) PCB. These are located just

in front of the four large capacitors; the

ribbon from J805A should be plugged into

J805B (the left of the pair, looking from

the rear) and that from J806A to J806B.

7. The remainder of the VTX-WM1 card’s

ying leads connect to the amplier’s

upper rear PCB. Plug the 14-way and

6-way ribbon cables at the right-hand end

of the VTX-WM1 card (from J801A and

J802A respectively) into Molex headers

J801B and J802B on the upper rear PCB.
