APPENDIX B
PATTON MODEL 2715
CABLE RECOMMENDATIONS
The Patton Model 2715 has been performance tested by Patton technicians using
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 2715 , please keep the following guidelines in mind:
•Always use twisted pair
•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. Use the above data rate/distance table as a general guideline only.
