APPENDIX B
PATTON MODEL 2094
CABLE RECOMMENDATIONS
The Patton Model 2094 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 2094 , 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 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.
