Connecting via Rm-1 Radio Modem

Connecting to an Em50R via a Rm-1 is different than connecting
via your USB cable. Keep notes concerning the Em50R name and
radio settings to make the rest of the system configuration easier to
accomplish.
Before you can use the telemetry options of your Em50R, you must
configure the Em50R by connecting it directly to your computer us-
ing your USB cable. Connect using ECH20 Utility or DataTrac 3
and set the Em50R Channel, Subchannel, and Radio Mode. See
the section on Configuring in ECH20 Utility for additional informa-
tion on configuring the Em50 series loggers. The Channel can be
set from 0 to 6 inclusive (default is 0). The Subchannel can be set
from 0 to 65534 inclusive (default is 0). To use the radio logger with
an Rm-1, the Radio Mode has to be set to one of the two-way modes.
If you choose the two-way 6:00-18:00 mode, then connection via the
Rm-1 can only take place between the hours of 6:00 AM through 6:00
PM. We designed this mode was designed to improve battery life by
not keeping the radio on constantly. The other two-way modes can
be connected to 24 hours a day.
After setting the Radio Mode, click the Apply button in ECH20
Utility. Disconnect from the Em50R logger. Now, connect your
computer to the Rm-1 by using a standard 9-pin serial cable. (A
USB version of the Rm-1 is also available.)
Choose the correct communication port in the Connect Via drop-
down menu. For example, if your Rm-1 is physically connected to
your computers COM1 communication port, you would choose "Rm-
1 on COM1 Communication Port" in the Connect Via menu. Click
the "Connect" button.
