4.0 MDL-Remote™ Application
AEC enhanced the MicroDataLogger data acquisition system (MDL) by adding
remote access capabilities. Remote access allows MDL users to automatically
retrieve data from loggers using a phone line and download data to a computer while
the equipment is still installed in the field. The ability to easily and quickly access data
from a remote site is the main benefit of this enhancement.
Designed to integrate seamlessly with MDL units, sensors & accessories, and MDL-
DataManager software, the new remote system includes the following components.
! MDL-Modem uniquely equipped for the MDL system to transfer data via phone
line.
! MDL-Smart Port that allows connection of up to 5 loggers per modem.
! MDL-Remote extended length cable for connectivity from the MDL to the Smart
Port or Modem.
! MDL-DataRetriever software automates data retrieval and splices collected data
into one “.log” file. (MDL-DataManager software does not provide automated
data retrieval or data splice features.)
MDL-Remote
Operation
MDL-DataManager and MDL-DataRetriever software can be used to remotely
configure and download data from MicroDataLogger units through the use of a
modem, and can also be used with a modem and Smart Port to enable remote
communication with up to five MDL units with a single modem. Once the software is
configured, remote communication with MDLs is nearly identical to local
communication over a local serial cable.
If a Smart Port is used, you can communicate with up to five MDL units, although you
cannot communicate with all of them at once. You must individually select which
MDL you wish to communicate with by selecting the desired Port ID in the MDL
Options dialog, discussed below.
To use the MDL-DataManager software to communicate with a remotely installed
MicroDataLogger unit, follow these steps.
While you're at the remote data collection site:
1. Install the MDL and sensors in the remote location.
Install the MDL and sensors. If you intend to leave the MDL in place for an extended
period of time, be sure to plug the MDL into a battery charger (CHARGE-02). This
will ensure that you can repeatedly download the logger without encountering a
battery failure. It also allows you to store data at high frequencies with no concern
about discharging the battery.
2. Configure the MDL for your application using MDL-DataManager software
version 4.0 or higher. (optional)
While you are at the remote site, it is good practice to configure the MDL to ensure
that all sensors are connected properly and that the readings are reasonable. You
can also perform this initial configuration remotely over a modem, but if there are any
problems with the physical setup of the loggers, you won't be able to fix it until you
take a trip out to the site. So to avoid disappointment, configure your loggers before
you leave the site!
