Sample initialization text file:
This is for reference and applies to an external US Robotics modem only.
ATM1 ; speaker off when connects
AT&B1 ; fixed serial port rate
AT&D2 ; normal DTR
AT&H1&R2 ; h/w flow control
AT&I0 ; disable s/w flow control
AT&K0 ; disable compression
Connect 19200
AT&M4 ; normal error control
Select the COM port for your modem
and the baud rate. Type in the phone
number or select it from the list of pre-
stored numbers. If necessary, click the "Use Initialization File" box and use
the browse button to search for the initialization text file for your modem. Click
"Connect" and the software will dial out, showing the status screen shown above.
Once a connection is established, "Connect" will appear for a few seconds along with
the baud rate of the connection. After connecting, the normal Global Logger screen
will appear and operate exactly as if a direct connection was made. All options and
features work the same but at a reduced communication speed.
When connecting the WL16S Data Logger to an external modem, a special cable is
required. Wiring diagrams are provided at the end of this manual and pre-wired
cables are available from Global Water.
The remote modem is configured by setting DIP switches. They should be set to
auto-answer on, DTR Normal, carrier detect normal and smart mode. Global Water
can provide external modems and interface cables at an additional cost if requested.
Contact our sales department for more information.
It may not be necessary to use an initialization string to configure the host modem
but if problems arise the modem should be set with software handshaking off (Xoff),
DTR normal, fixed baud rate, compression off and error correction on. This
configuration is done by building an initialization file using the standard AT
commands and loading it into the connection screen.
