GigaLog

GigaLog is a data logger for up to 2 Gbytes of data using CompactFlash memory cards.
With GigaLog any embedded system can log its data easily, for a very long period, and readable by a PC.

GigaLog automatically recognizes CompactFlash memory cards, their size, formats the disk, creates a MSDOS compatible file system, and creates files to store the data into it. When switching power on, or changing the memory card, new data will be appended to the files. Stored data can be read on a PC using a simple CompactFlash adapter. The memory card appears as a removable disk to the PC. All data from the RS232 is in a single file, analog data in another file on the disk.

Storing data from 8 analog or digital inputs
Gigalog E has 8 inputs. Gigalog F has 16 inputs. Each input can be configured as analog, digital, or counter. Gigalog samples these inputs regularly and stores them on the disk in a file.

Storing incoming data from RS232
All data coming in from the serial RS232 interface will be stored on the disk in a file. A data frame from the RS232 is any consecutive data until there is a gap of at least 0.5 seconds. GigaLog can be configured to add a time stamp (yyyy:mm:dd hh:mm:ss) in front and/or at the end of a data frame.

Remote Control (Gigalog F)
GigaLog F can be completely controlled by a modem: Verify state, change configuration, disk handling, upload logged data. Each input has a min and a max threshold. When the input violates a threshold, an alarm occurs. An alarm may toggle a relay, write a message into a disk file, call a centre using a phone, or send an SMS, using a GSM modem. You may define a command macro, that calls a centre, or sends an SMS each hour, day, or once a week.

A LED on the board shows that GigaLog is storing data on the disk. When the LED is off, data is safe, you can remove the CompactFlash card.

GigaLog is available as board or in a housing to be mounted on a DIN rail.
GigaLog includes all tools to write your own firmware: C compiler, debugger, firmware source, documentation.

GigaLog stores 8 analog inputs:	2003:07:24 11:56:30:315 109 789 833 1020 911
Incoming data from Rs232:	machine error 51
GigaLog adds optional timestamp	2003:07:24 11:56:30 machine error 51

When the data frames follows a certain format, PC utility program Gigadata (included) can be used to visualize the data on the PC.

GigaLog completely programmable in C
To customise the board, you may write your own firmware in C, and download it into GigaLog.
Delivered with the board: IDE under Windows, C compiler, library for the board, debugger, firmware examples.
