The CCU-721 gateway provides utilities ease of installation and integration, as well as a user-friendly front panel interface for field personnel.
Overview
The Cooper Power Systems CCU-721 carrier control unit acts as a gateway to Cooper Power Systems power line communications and offers advanced communication algorithms. The CCU-721 carrier control unit is linked to the master station by a dedicated voice grade communications line. Coax cable assemblies are used to couple the distribution bus to the primary coupling assemblies. The CCU-721 carrier control unit directs communications initiated from the master station to power line communications devices.
The CCU-721 carrier control unit can also operate in a stand-alone mode for time synchronizations or operate using an expanded protocol (IDLC) which can coexist on a channel with properly configured SCADA RTUs.
Features
The features of the CCU-721 carrier control unit are:
· A weatherproof enclosure for indoor/outdoor mounting with all the controls on the inside of the enclosure
· Power switch control
· Circuit breaker control
· Front panel HMI interface control
· A dual 120 VAC receptacle
· Interfaces with up to four distribution buses
· Handles one-way or two-way Cooper Power Systems power line communications
· Internal time base
· Support of optional internal processes and algorithms
· Internal Cooper Power Systems power line communication command generator and decoder for use by internal algorithms
· USB Serial port for on-site testing
· Plug-in circuit boards for quick servicing
· Ethernet port for easy communications setup
· Transmit/receive indicators for diagnostics
Capabilities
The capabilities of the CCU-721 carrier control unit are:
· Translation of message from the master station to
Cooper Power Systems power line communication message protocol.
· Communication error checking using BCH code and
CRC code detection methods.
· Ability to accept up to 32 master station request commands in a queue to permit independent communication on both the data link to the master station and the Cooper Power Systems power line communications system.
· Time tagging of each request as it is added to the queue to help determine when it will be processed.
· Requests that are handled on the basis of priority and time. Items of equal priority are treated on a first- infirst-out basis.
· Internal automatic time synchronization algorithm with both continuous and event triggered operation.

CCU-721
Applications, Mounting and
Connections for a CCU-721 Carrier
Control Unit
Applications
The CCU-721 carrier control unit interfaces between the master station and transponders located in the service area of a distribution substation. The master station initializes the CCU-721 carrier control unit’s local algorithms, monitors the actions of those algorithms, and can directly request the CCU-721 carrier control unit to perform power line communications.
Mounting and Connections
To order a CCU-721 carrier control unit , select the style by choosing the
Cooper Power Systems power line communications frequency.
For outdoor installation, the power cord can be removed and an outdoor cable inserted through the strain relief in the bottom of the CCU-721 carrier control unit’s cabinet.
The CCU-721 carrier control unit is ready for wall mounting out of the box and can easily be configured for pole mounting with no other necessary hardware required. Simply mount the CCU-721 carrier control unit in the desired location, ground the enclosure, and supply 120 VAC to the CCU-721 carrier control unit .
