Configuring the Encore 61000 DataNode for Modem Communication
The Encore 61000 DataNode can be configured to communicate with the Encore Series
Encore 61000
DataNode
Software running on a computer (or 5502/5504 InfoNode) using analog or land-based
modems (versus GSM/GPRS wireless modems). For communication to operate
properly, a compatible modem would need to be connected to the serial port on the rear
panel of the 61000, as well as to the computer (either internal card-based or external
modem). The recommended modem for the 61000 is a 61MDM, which is a 56kbps
modem.
The 61000 can collect a large amount of data, depending on how it is set up and on the
NOTE
amount of event activity. Data size of 10Mbytes per day is not unusual. Downloading
this amount of data from a number of 61000 units through analog modems may not be
practical in larger systems, since download time multiplied by the number of units may
exceed the polling rate. A 56kbps modem will typically download maximum of 3-
5kbytes per second, which requires approximately an hour to download a day's data.
The number of waveforms per event and the number of journalled parameters should
be limited in such applications.
Configuring the Encore 61000 DataNode for modem communications consists of five
Procedure
major steps: setting up the modem for use with the 61000 unit; configuring the
computer to set up 61000 for modem communications; configuring the 61000
communications for modem operation; setting up the dial-up network for the computer;
and 61000 DataNode setup in Encore Series Software. Follow the instructions below to
configure the system for modem communications.
STEP 1: Set up the modem for use with the 61000 unit.
1.1 Connect the modem to the computer's serial port with a "straight-through"
serial cable.
1.2 Use HyperTerminal to connect to the modem with the following settings:
HyperTerminal Settings:
1.3 Turn off the ECHO function by typing ATE0<cr>.
1.4 Turn on the RTS/CTS hardware flow control by typing AT&K3 <cr>.
1.5 Save the changes to the modem's setup memory by typing AT&W<cr>.
