NTAS/SOFS MET BLOGR24 Commands - Firmware Ver 5.xx with internal SBD Iridium Support

See BLOGR24 OPERATIONS document for instructions on how to hook up the comms link to your PC.
Refer to Latest Version Information for reference info on latest firmware version numbers.
Ver 5.xx is based on NTAS/SOFS MET LOGR53 Firmware Ver 4.2x with internal SBD support.

MET Logger always comes up running and logging in fixed configuration - see 'default' config below.

BLOGR24 UPGRADE NOTE - The BLOGR24 hardware consists of a single PC board in the same form factor as the earlier LOGRIF PC board (which was part of a two board set with the VMLOGR53 CPU PC board). It will fit the same chassis used previously, and all wiring connectors on the new BLOGR24 PC board are the same and in similar positions to the older LOGRIF PC board.   I.E. the BLOGR24 is a drop in replacement for the older two board set.

SDHC NOTE 1 - Firmware Ver 5.xx has been tested using SanDisk SDHC cards of 2 GB, 4 GB, and 8 GB on WHOI BLOGR24 Rev A buoy logger boards.

SDHC NOTE 2 - SDHC cards MUST be initialized using the I command choice in the SDOK command menu. SDHC cards may be read on a PC and will contain 3 files: a BLOGR24.ID file, a BLOGR24.INF file, and a BLOGR24.DAT file. Refer to SDHC Storage Format for details.

NOTE for loggers with ATTACHED REMOTE COMMUNICATION CAPABILITY (e.g. external Iridium Comms (ICC) unit): ALWAYS verify that the Comms system is operating correctly before final deployment.   For the first 60 minutes after powerup, the logger can be STOPped by an incorrectly programmed Comms system. After the first 60 minutes, and if the Comms system power is controlled by the logger, no STOP command will be accepted by the logger while Comms system power is ON. This offers some protection from accidently disabling the logger remotely. Of course, if Comms system power is independent of logger control, be very careful!

NOTE for loggers with INTERNAL IRIDIUM SBD CAPABILITY: Firmware supports hourly messages of ASIMET MET data and WMO-compliant MET data via an NAL Research 9602N Iridium modem attached to P21 on the BLOGR24 board. See Iridium SBD message Format for internal Iridium SBD message format.
