2.0 Cable Requirements
RS-232 Serial Cable
• four conductor, shielded, stranded, AWG 24 wire (Belden 9534 or a larger gauge)
• 50 feet maximum length (per RS-232 industry specification - greater lengths are not recommended)
RS-485 Network Cable
• two conductor, shielded, twisted pair, stranded, AWG 24 wire (Belden 9501 or a larger gauge)
• 16,000 feet total network length
• refer to the Network Wiring
Application Note (P/N 01824-002) for specific network wiring information
Input Power
• two conductor, stranded, AWG 18 wire (Belden 8461 or a larger gauge)
• 200 foot maximum length for systems using an SB-293 with two readers
NOTE: On long power cable runs, the cable resistance causes a drop in voltage at the end of the cable run. Be sure your
power supply does provide 12 VDC at the end of the cable run.
