RS-485 Repeater Communication Kit
Electronic Technician Assistant (ETA)

  RS-485 is the most common communications standard for DDC controllers; however, it is limited to 32 unit loads and 4,000 feet. Extending the network beyond 32 unit loads or 4,000 feet requires repeaters.
  The RS-485 Repeater Communication Kit provides all the functions for one repeater and remote RS-485 network, plus it comes in a self-contained, easy-to-apply and cost effective assembly. The kit also aids in troubleshooting because LEDs indicate when power is applied and communications are present.
  The RS-485 Repeater Communication Kit includes:
  • One RS-485 Repeater (RPTR) module which connects two RS-485 segments together. Data from one segment repeats to the other segment and vice versa. Each RPTR module allows an additional 32 unit loads and 4,000 feet;
  • A 350 mA voltage converter (VC350) to provide the higher current necessary for flawless communications;
  • A Single Repeater Back Plane (SRBP) to mount the RPTR module and provide pluggable connectors for power and three RS-485 cables;
  • A four inch long piece of 2.75" snaptrack to easily mount the entire assembly.
