APPENDIX B
CABLE RECOMMENDATIONS
The Patton Model 2500RC Series operates at frequencies of 20kHz
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.
To gain optimum performance from the Model 2500RC 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 above data rate/distance
table as a
general guideline only.
