Introduction
The SMN-890 SmartNODETM RFID Receiver is an integral component of
the SmartSense Wireless Vital Signs and Location Tracking System. The
system is designed for wireless and automated measurement and
recording of patient vital signs and for location tracking of patients and
high-value assets.
The SMN-890 will periodically transmit IR beacon signal. This beacon
signal consists of unique location ID. This location will be received by tags
which are in range. IR signal are much localized which give better location
tracking determination.
TM
The SMN-890 SmartNODE RFID Receiver is a LAN-enabled receiver for
receiving data transmitted by the SmartSenseTM series of wireless sensors
and monitors. The receiver uploads data received from the sensors to the
SmartSenseTM database via its built in Ethernet LAN interface.
In a typical installation, the receivers are to be installed at strategic
locations in the hospital in a manner to meet the specific coverage
requirement of the application. The receivers being Ethernet LAN capable
lend themselves well to deployment using standard Ethernet LAN
equipment and infrastructure.

7.1 Ceiling Mounted
7.1.1 Soft (Mineral Wool) Ceiling Board
1.
In general for soft (Mineral Wool) ceiling board, 2 mounting
plate are used. The 2 mounting plates should be affixed using M6
(3/8” inch) type metal screws up to the length of false ceiling
material.
Figure 10: Side View of a Mounting Plate
24
2.
Once the mounting plates are fixed to the ceiling, the SMN890 should be pushed and then it is slid into the plate to place to
mount the reader properly.
3.
A hole should be made in the ceiling for the LAN cable to
drop out from the ceiling into the Receiver. This cable will be
interfaced to the Active RFID Receiver using a standard TCP/IP
port available on the back of the Receiver using a standard RJ-45
connector. It is as shown on figure 11 below.
Figure 11: SMN-890 mounted on soft board ceiling using 2
mounting plate
25
7.1.2 Gypsum Ceiling Board

used. The mounting plate should be affixed using proper wall plug
for gypsum ceiling board.
2.
Once the mounting plate is fixed to the ceiling, the SMN-890
should be pushed and then it is slid into the plate to place to mount
the reader properly.
3.
A hole should be made in the ceiling for the LAN cable to
drop out from the ceiling into the Receiver. This cable will be

26
7.2 Wall Mounted
1.
Typically, a wall mounted Active RFID Receiver requires
three holes on the wall surface to mount the base of the wall mount
bracket by using wall plug type 10mm with 14-18 screw size.
Figure 13: Wall mounting bracket
2.
The length of the screw depends on the strength of the wall
that can hold the Active RFID Receiver that weights approximately
600 grams.
3.
A ceiling-to-wall conduit fitting should be laid until the base
of the wall mounted bracket to install LAN cable and from there it
should be linked up to back of the Receiver using a standard RJ-45
connector. It is as shown on figure 14 below.

9. Assemble of External Magnetic Lock
This section illustrates the method to assemble external magnetic
lock with SMN-890S.
1. Unscrew the SMN-890 front case.
2. Connect the wire as shown on figure below. Make sure the both
contacts have been tightened properly.
30
10. IR Detection Operating Principles
IR signal is line of sight and cannot penetrate through wall. Thus, it
is accurate in room base level tracking. IR signal tend to bounce
from blocking material (IR reflector) such as concrete wall, table and
etc. These IR reflectors will act as secondary IR source and help to
scatter the IR signal to any direction in a room. As a result, an IR
receiver, from any direction, in a room will be easily to pick up IR
signal. Below examples illustrate the placement SMN-890 in each
scenario to achieve best IR reception result.
SMN-890
1. The SMN-890 should be placed at centre of a room so that it
can achieve larger IR coverage area.
2. Try not to place SMN-890 facing the door way in order to
reduce IR spill out from a room.
31
11. Trouble Shooting Guides
1. How to know if SMN-890 is connected to the network
successfully?
Try to ping SMN-890 assigned IP address using command prompt.
If it is connected to the network, ping action should be successful.
If it still fails, check the LAN cable and make sure it is working.
Figure 15 below illustrates the example of pinging the network
device.
Figure 15: Ping network device.
2. Why SMN-890 cannot power-up by POE switch?
Make sure the switch’s ‘Power over Ethernet’ feature is enabled
for all the ports.
3. How to I verify if SMN-890 able to contact with server?
By using the web browser, try to browse the SMN-890 Web. As
shown on ‘figure 3 on Page 10’, SMN-890 web will show the latest
server uploaded date time if it is able to contact with server
successfully. The last uploaded date time should not be more
than 4 minutes behind current date time.
32
4. I can ping SMN-890 but SMN-890 seems not able to contact with
server. What should I do?
Try to ping the server IP to make sure the server is contactable in
network first.
If the server is able to ping, open the SMN-890 ‘server settings
configuration page’, make sure server IP address and port are set
correctly. If only one server is used, make sure the 4 server IP are
set to same value. For the changes of setting to take effect, click
‘save’ button then reboot the device by clicking the ‘reboot’ tab.
‘Figure 6 on page 13’ shows the ‘server settings configuration
page’.
If SMN-890 is still not able to contact with the server, check the
firewall settings of the server. Make sure the server port is not
blocked by firewall.
5. How to know if SMN-890 able to receive data from the sensor?
When SMN-890 receives data from sensor, the UHF Led will
blink. It is shown on ‘figure 2 on Page 6’. Besides, you can open
SMN-890 statistic web page. The SMN-890 will show how much
data has been received since it is power-on.
If SMN-890 cannot receive any data, make sure the SMN-890 RF
frequency is set correctly and there is a tag within its coverage
range.
6. Why SMN-890 Led keep blinking once it is power-up?
Once SMN-890 is power-up, its Led will keep blinking to indicate
SMN- 890 now is in boot loading stage. When it is boot loaded
successfully (after 10 seconds), the Led will stop blinking.
7. Why the Green Led on SMN-890 front side keeps blinking?
The blinking of this green led indicates SMN-890 is transmitting
IR signal. The blinking frequency indicates the SMN-890 IR
transmitting frequency. As thus, the green led will not blink if
SMN-890 IR transmission is disabled.
