Mini 3120 and 3150 Power Line EVB Evaluation Boards
Summary
The Mini 3120 and 3150 PL EVB Evaluation Boards will not communicate on a LONWORKS network until you enable or disable the CENELEC access protocol. The access protocol is a European-standard protocol for controlling access to a power line used for communication. It is required for PL-20 devices in most of Europe, but is not required or typically used outside of Europe. All PL-20 devices on a power line channel must be the same mode. A Model 28005 MiniGizmo I/O Board is required to enable of disable the CENELEC access protocol on a PL EVB — this board is included with the Mini EVK but is not included when you order standalone evaluation boards. If you are installing the evaluation boards in the Mini EVK, see Step 3 of the Mini EVK PL-20 Quick Start Guide for instructions. If you are installing a standalone EVB, use the steps in the following solution.
Solution
1. When you power up the new EVB, LED1 flashes to indicate that the EVB is in CENELEC configuration mode. LED8 indicates whether the CENELEC access protocol is enabled or disabled—if the LED8 is on, the CENELEC access protocol is enabled.
2. Enable or disable the CENELEC access protocol by pressing SW8 until LED8 indicates your desired selection.
3. Press SW1 to confirm your selection and exit CENELEC configuration mode.
You only need to follow this procedure once per board—your selection is saved in non-volatile memory. See Chapter 8 of the PL 3120/PL 3150 Smart Transceiver Data Book for more information about the CENELEC access protocol
Alternative Solution
You can also solve this problem by replacing the PROM on the PL 3150 EVB with a PROM containing a custom application image that you create with the Mini EVK or NodeBuilder® software. For this solution, see the Mini EVK User’s Guide or the NodeBuilder User’s Guide for instructions on how to create a custom application image.
