APPENDIX B
CABLE RECOMMENDATIONS
The Patton Model 1060RC operates at frequencies of 100kHz or
less and has been performance tested by Patton technicians using
twisted-pair cable with the following characteristics:
W
ire Gauge Capacitance Resistance
19 AWG 83nf/mi or 15.72 pf/ft. .0163W/ft.
22 AWG 83nf/mi or 15.72 pf/ft. .0326W/ft.
24 AWG 83nf/mi or 15.72 pf/ft. .05165W/ft.
Using or simulating cable with the above characteristics, the
following data rate/distance results were obtained by Patton during
bench tests:
Data Rate (Bps)
Gauge (AWG) / Distance (Mi)
19 22 24
57,600 2.5 1.8 1.3
38,400 3.7 2.3 1.7
19,200 5.1 3.4 2.4
9,600 6.7 4.6 3.7
4,800 9.4 6.6 5.3
2,400 11.5 9.3 7.6
1,200 14.0 12.0 9.6
To gain optimum performance from the 1060RC, 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.
• Environmental factors too numerous to mention can affect the
maximum distances obtainable at a particular site. Use the above
data rate/distance table as a
general guideline only.
