Technical Support.PRODUCT DESCRIPTION

The Patton Model 470 Series ATM balunsallow 75 ohm coax

hardware to communicate with 100 Ohm, 120 Ohm, or 150 Ohm twisted

pair equipment. The Model 470 Series presents a ready solution to this

termination mismatch. Supporting ATM data rates to 155.52 Mbps, the

Model 471/471/472 convert 75 Ohm signals and vice versa to 100, 120,

and 150 Ohm twisted pair, respectively.

Model 470: 75 Ohm to 100 Ohm CAT-5 Single 8-Pin RJ-45 Jack,

Model 471: 75 Ohm to 120 OhmCAT-5 single 8-Pin RJ45 Jack,

Model 472: 75 Ohm to 150 Ohm IBM Data Connector (2 Twisted Pair)

CONFIGURATIONCONFIGURATION

The Model 470 Series are pre-set to work in most applications

without additional configuration. The only parameter that is user-

configurable 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.

or IDC (150 Ohm)

TX ShieldJP2RJ-45 Shield, IBM IDC Shield

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 470 Series 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 two pins on the right (for JP1) and from the

2 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.

INSTALLATION

The Model 470 Series is easy to install and requires no AC power

or batteries for operation. After making any necessary configuration

changes (see above), simple plug in the modular and coax cables as

indicated on the case. The pin/contact configuration of the 100/120

Ohm RJ-45 and 150 Ohm IDC modular connectors is shown below:
