AN021 - RS-485 with a Power Bus over a 4-Wire Cable
- Summary :
Many companies use RS-485 with a 4-wire bus design - with 1 twisted pair wire
for RS-485 and 1 heavier wire pair for a 12 or 24vdc power bus. The creative
use of isolated RS-485 repeaters offers great flexibility in fitting the
bus system to the actual cable trench and trunking layout present on site.
