Patton electronic Asynchronous, 1012ARC Cable Recommendations, Wire Gauge Capacitance Resistance

APPENDIX B

CABLE RECOMMENDATIONS

The Patton Model 1012ARC 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.

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	24	26
Up to 38,400	6.0	3.5	2.0

To gain optimum performance from the Model 1012ARC, 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 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.
