The Niobrara BB85 is a small DIN rail mounted breakout box intended to simplify connection between a Modicon® style RS-485 port with an RJ45 connector and a 2-wire or 4-wire RS-485 network.
The BB85 makes linking a CNOE, CNOS, CUCM, QUCM-O, QUCM-OE or a Momentum™ RS-485 Serial Option Adapter to a network of POWERLOGIC® devices easy; there is no need to install a modular plug. The RS-485 terminal block uses the pinout familiar to POWERLOGIC users (see diagram below).
A Niobrara MM0 RJ45 straight-through cable is supplied with the unit to connect the QUCM, CUCM, CNOE-800, CNOS-001 or other device to the BB85. The POWERLOGIC or other RS-485 network is then connected to screw terminals having the pinout familiar to POWERLOGIC users.
Niobrara can provide cables for other RS-485 pinouts and connectors to utilize the BB85; contact the factory for details.
Below is a pinout diagram of the BB85 showing standard POWERLOGIC cabling on the terminal block:
