PRODUCT DESCRIPTION

The Patton Model 462 and 463 G.703 baluns allow 75 ohm coax

hardware to communicate with 100 Ohm and 120 Ohm twisted pair
equipment. The Model 462 and 463 present a ready solution to this
termination mismatch. Supporting G.703 data rates to 8 Mbps, the
Model 462 convert 75 Ohm signals and vice versa to 100 ohm twisted
pair. Model 463 operates up to 34 Mbps and bi-directionally converts 75
ohm coax to 120 ohm twisted pair.

Model 462: 75 Ohm to 100 Ohm CAT-5 Single 8-Pin RJ-45 Jack,
Model 463: 75 Ohm to 120 Ohm CAT-5 single 8-Pin RJ45 Jack,

CONFIGURATION

The Model 462 and 463 are pre-set to work in most applications
without additional configuration. The only parameter that is user­configurable is shield connection between the 75 Ohm coax and twisted
pair interfaces. The diagram below shows how the shield is connected
between the modular jack and dual BNCs. Removing the jumper
breaks the connection.

Coax BNC (75 Ohm

Jumper RJ-45 (100/120)

TX Shield JP1 RJ-45 Shield, RJ-45 Pin 3
TX Shield JP2 RJ-45 Shield, RJ-45 Pin 6

The factory setting leaves both jumpers JP1 and JP2 in place, thus
passing both shield connections through. To break one or both of the
shield connections, follow these instructions:

1) Insert a small flat blade screwdriver into the slot on the side of
the Model 462 and 463 case and twist. The case will pop
open, exposing the PC board.

2) Holding the PC board with the modular jack facing left,
located jumper JP1 toward the top of the board and JP2
toward the bottom of the board. Remove the desired
jumper(s) from the three pins on the right (for JP1) and from
the three pins on the left (for JP2) to break one or both shield
connections. NOTE: do not lose the jumper(s).

3) Re-align the case halves and end inserts and snap the case
halves back together.
