Gateway - Socket Technical Manual
Chapter 2. The Gateway Transceiver
an outlet on a circuit different from that to which the
receiver is connected. - Consult the dealer or an experi-
enced radio/TV technician for help
This device complies with Part 15 of the FCC Rules
and Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference, including interfer-
ence that may cause undesired operation of the device.
The Gateway
The Gateway is a
transceiver (transmit-
ter + receiver) that
communicates with
the wireless recorder.
The Gateway sends
the encrypted data via
a wireless phone net-
work to the receiving
location. Both the
recorder and the Gate-
way are able to trans-
mit and receive data to
ensure that encrypted
data arrives at its
desired location.
The Gateway comes with a power cord and antenna that
need to be attached into the front of the Gateway. The
antenna should be in an upright position. When located
in the patient’s home, the Gateway should be located in
a central location. If the patient is away from the Gate-
way for an extended period of time, like going to work,
the transmission will take
place when they return.
The Gateway has three
lights. The third light
(right-most), is the wire-
less connection indica-
tor. When initially
plugged in, this light will
flash red at a very high
rate. After that, if the
light is blinking between
3 to 4 times in a row, there is an acceptable wireless
connection. If it only blinks two times in a row, there is
a questionable connection with the cellular network,
and the Gateway should be moved to a better connec-
tion. If the light only does a single blink, there is no
connection at all to the wireless network.
The middle light is the recorder indicator. It will turn
red when the recorder is communicating with the Gate-
way. This may occur when pairing the recorder with the
Gateway or when ECG data is being transmitted.
The green light on the left, indicates that your Gateway
is getting a reply from the receiving station. This will
flash very quickly when communicating externally.
Data Security
For Wireless transmission via the Gateway, data is
encrypted using symmetric 256-bit encryption key on
the recorder and is sent in data block. One or more
blocks can be sent at a time. Once the data is received
via the Event Decoder, the encryption key will be used
to decrypt the data into a readable format. The Key ID
is visible on the both the recorder and the Event
Decoder. The two Key IDs must match in order for files
to be transferred and decryption to take place.
