Chapter 1. Introduction to Wireless Event
1. Introduction to Wireless Event
The NorthEast Monitoring patch-style DR400 record-
ers come with a Wireless feature that uses Bluetooth
technology to communicate with a paired device. For
event transmission, the communication occurs between
the recorder and a paired NorthEast Monitoring Gate-
way (black box). Wireless transmission is initiated
when the DR400 is in Event recording mode and there
is event data to transmit.
For event recording, the patient takes home a paired
Gateway and places it in a location in the home where a
4G signal is detected and the patient is often nearby.
Once an event is recorded, the DR400 will attempt to
locate the Gateway to transmit the event.
If the patient is away from the Gateway for an extended
period of time, the recorder will continue to try to trans-
mit at regular intervals. Once the patient is back in close
proximity to the Gateway, and a transmission is suc-
cessful, all events in memory will be sent at that time
starting with the oldest.
During a successful wireless transmission, encrypted
event data is sent via the airways through a cell phone
signal to an FTP site identified on the recorder. When
an event file is successfully received at the FTP site, the
DR400 reads the file back, checks it, confirm it for
accuracy and will delete the event(s) from its memory.
Once on the FTP site, the Event Decoder utility down-
loads the event file to a local temporary location and
deletes the file from the FTP site. The Event Decoder
will then decrypt each file and place it in a designated
location for LX Event. Once the data is received, you
are able to access this data via the Incoming Files
screen in the LX Event utility.
2. The Gateway Transceiver
After being paired with a recorder, the Gateway is sent
home with the patient for automatic wireless transmit-
ting to the receiving location.
The Gateway Kit includes:
•
Gateway (part number NEMP00458)
•
Antenna (NEMP00451)
•
AC Adapter (NEMP00453)
As per FCC rules section 2.1091, only the antenna sup-
plied is to be used and that the antenna must be in a
location where it will be at least 20 CM (8 inches) from
locations where any person will commonly be located.
