Modem Connection - Global Water GL500-7-2 Manual

VIII.

Modem Connection:

Access to the GL500 can be made through dial-out to a remote modem by clicking
the "Modem" option. The connection from modem to logger requires an RS-232
serial modem, USB modems are not supported as an interface to the logger. Also,
some switch settings must be made to the remote modem and an initialization string
may be required to properly configure the host modem.
Two baud rates are supported 9600 and 19200. Should you experience difficulty
establishing a reliable connection at 19200, use the slower connection speed. Note
that due to the slower baud rates and the additional handshaking performed during
modem communication, The Global Logger software will operate significantly slower
than during a direct connection.
The Global Logger software will remember the last 4 numbers dialed and has a
provision for using a stored text file (.txt extension) for initialization of the host
modem using standard AT commands. Some experience may be required to
configure your modem but a sample command file and some useful tips follow.
Select the modem's COM port
