APPENDIX B

1090 CABLE RECOMMENDATIONS

The Patton Model 1090 operates at frequencies of 160 kHz or less and
has been performance tested by Patton technicians using twisted-pair
cable with the following characteristics:

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.

26 AWG

83nF/mi or 15.72 pF/ft.

.08347 Ohms/ft.

To gain optimum performance from the Model 1090 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 higher 
AWG numbers than 26).

• 

Use of twisted pair with a resistance greater than the above 
specifications may cause a reduction in maximum distance 
obtainable.  Functionality should not be affected.

• 

Many environmental factors can affect the maximum distances
obtainable at a particular site.  Use the data rate/distance table
(below) as a general guideline only.
