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
NOTE: When wiring the RS-485 terminal block connector, be sure to use the smallest connector provided. TB1 is
smaller than the other terminal blocks and will only accept the smallest terminal block connector provided.
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.
Earth Ground
• Single conductor, AWG 18 wire (or a larger gauge)
1
Keri Systems Proximity Readers
•
six conductor, shielded, stranded, AWG 24 wire (Belden 9536 or a larger gauge)
• four conductor, shielded, stranded, AWG 24 wire (Belden 9534 or a larger gauge) for the MS-4000 only (there is no
beeper or LED in the MS-4000)
• see Table 2 for maximum cable lengths
1. Ground wire is green with or without yellow tracer.
