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
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.
