APPENDIX B
PATTON MODEL 1060 CABLE RECOMMENDATIONS
The Patton Model 1060 is designed and tested to communicate
over twisted-pair cable with the following characteristics:
Wire Gauge Capacitance Resistance
19 AWG 83nF/mi or 15.72 pF/ft. .0163Ω/ft.
22 AWG 83nF/mi or 15.72 pF/ft. .0326Ω/ft.
24 AWG 83nF/mi or 15.72 pF/ft. .05165Ω/ft.
Using the above characteristics as a baseline, we estimate the
distance limitations for the Model 1060 to be as follows.
To reduce the potential of difficulties in the field, we recommend that
the cable used to connect the Model 1060s have a capacitance of no
greater than 20pF/ft., and that the wire be no thinner than 26 AWG.
The Model 1060 is designed to withstand normal environmental noise
and conditions. However, other environmental factors too numerous to
discuss may affect proper operation.
The distance table above should
be used as a general guideline only.
