The TDS2020CM2 Compact Flash and PCMCIA adapter sits on top of a TDS2020F board to form a datalogger module.
With this module you can quickly build tailor-made data collection systems with removable memory that can be read by a personal computer. It is an ideal way to save time and money designing custom loggers.

How much data can I log?
The TDS2020F computer card carries a TDS2020CM2 PCMCIA piggyback adapter. Add removable Flash-ATA, Compact Flash, RAM or hard disk memory cards as appropriate to the application. The amount of data you can collect is limited only by card capacity, currently over a gigabyte.
What can I log?
l Analog inputs of 6,10, 12 or 16 bit resolution
l Digital states, up to 39 of them
l GPS location, altitude, speed, direction |
l Date and time
l Humidity, temperature & dewpoint
l Count of input pulses on up to 8 channels |
l Frequency of signals on up to 8 channels
l Microseconds to months logging intervals
l Serial data from RS232 (or USB or Ethernet with accessories) |

Getting data into a personal computer or laptop could not be easier.
On recovery of the module from the field put the disk or RAM card into a PC card slot and, without any special software, copy your data to a file in the PC. Alternatively recover data to a parallel printer, or send it through a serial port, perhaps to a modem or over a telephone or radio link. See Modems |
Unlike PC solutions, the emphasis is on low power
The storage card is electrically disconnected most of the time. It is not even in standby: it consumes nothing. The software is written so that the card powers up as infrequently as possible. Between data readings the system itself may be put into standby so the Data Logger Module will consume less than 200µA most of the time.
The module can take up to 41,000 samples/sec from the A to D under interrupt and still leave enough processing power for the foreground program to drive a keypad and display. Eight times this rate is possible with no foreground program. The computer and card memory board both work on 6 to 16V making the pair particularly suitable for battery-powered portable applications.
The system can be programmed to wake up from standby to collect data at specified intervals from 30 times per second to once a year. |
