M550/M650 Solar Marine Light Remote Programming
NexSens M550 and M650 Solar Marine Lights purchased with CB-Series data buoys will most often arrive pre-programmed for use. However, the IR remote may be used to change configuration settings using the codes provided in the table below. Note that activation commands need to be sent with the remote facing the side of the beacon. If no response to the below commands is elicited, try changing the angle of the remote with respect to the beacon.

Beacon Commands
| Command Type | Remote Input (M550 Beacon) | Remote Input (M650 Beacon) |
| Activate Remote | Hold PWR button for 2 seconds | Hold PWR button for 2 seconds |
| Unlock Code | N/A | PWR 753 √ (must be sent before the first command) |
| Power On | Hold PWR button for 4 seconds | *Set desired flash code |
| Power Off | Hold PWR button for 6 seconds | PWR 000 √ |
| Check Battery Status | PWR 810 √ or i | PWR 810 √ |
| Check Battery Response | 3 flashes – Good (>70%) 2 flashes – Charge (14-70%) 1 flash – Low (<14%) | 10 flashes – Good (>4.2V) 7 flashes – Charge (3.9-4.2V) 5 flashes – Low (<3.9V) 4 flashes – Bad (Replace) |
*For the M650 beacon, the effective intensity setting determines which flash codes will be sustainable given the solar recharge capability. For example the 066 Flash Code will not be accepted with the default 25cd intensity setting and must be reduced to at least 15cd for it to be applied. Once the intensity is reduced via the display interface at the base of the beacon it will be possible to then set the code.
Solar Marine Light Manuals & Quick Start Guides
Different flash codes may be programmed if desired. Reference the manuals below for a complete list of available flash codes and instructions for setting the code. Reference the quick start guides for confirming beacon battery status and mounting to NexSens CB-Series data buoys.
