APPENDIX B

PATTON NETLINK-T1™ MODEL 2720

CABLE RECOMMENDATIONS

The Patton Model 2720 Series has been performance tested by

Patton technicians using twisted-pair cable with the following charac-

teristics:

Wire Gauge Capacitance Resistance

19 AWG 83nf/mi or 15.72 pf/ft. .0163 Ohms/ft.

22 AWG 83nf/mi or 15.72 pf/ft. .0326 Ohms/ft.

24 AWG 83nf/mi or 15.72 pf/ft. .05165 Ohms/ft.

To gain optimum performance from the Model 2720 Series, please

keep the following guidelines in mind:

•

Always

use twisted pair wire—this is not an option.

• Use twisted pair wire with a capacitance of 20pf/ft or less.

• Avoid twisted pair wire thinner than 26 AWG (i.e. avoid AWG

numbers higher than 26)

• Use of twisted pair with a resistance greater than the above

specifications may cause a reduction in maximum distance obtain-

able. Functionality should not be affected.

• Many environmental factors can affect the maximum distance

obtainable at a particular site.
