PRE-INSTALLATION CONSIDERATIONS
Choosing a location: (See Figure 1)
1) Anticipated Range: Plan installation to stay within the
range of the antenna selected. Monitor's standard
antenna (small rubber duck style) can achieve dis-
tances of 5000 ft (1 mile) or greater in ideal conditions.
Longer transmission distances can be achieved with
higher performance antennas.
2) Idealizing Range: The 900MHz frequency band is
capable of propagating around obstacles. However,
optimum performance is achieved when antennas are
positioned in the line of sight of each other. Whenever
possible, select antenna locations that are elevated
and where the signal can travel without being impeded
by large steel obstacles (such as the steel buildings).
An example of an ideal installation is as follows: One
Wireless Communication Interface (radio/antenna) is
on an office roof wired to the control system (i.e.
SiloTrack™system) and the second Wireless
Communication Interface (radio/antenna) is on the top
of the silo attached to a safety railing wired to the
sensors.
3) Cabling effects: Due to the low transmission power of
the radio, it is preferable to keep the antenna as close
to the Wireless Communication Interface (radio mod-
ule) as possible. Whenever possible mount the anten-
na directly to the Wireless Communication Interface
(radio module). In some challenging applications, it
maybe necessary to install a higher performance
antenna that requires co-axial cabling between the
radio and the antenna. The co-axial cable introduces
loss into the system thereby negating some benefit of
the better antenna. In these applications, keep the
coaxial cable as short as possible. Monitor's standard
length is three feet (perhaps just long enough to reach
past/through a metal barrier). It is always preferable
to use the hardwired medium (RS-232/RS-485) to span
the distance from the control system/sensors to the
Wireless Communication Interface (radio module) than
to use extended lengths of coaxial cable to span the
distance between the Wireless Communication Inter-
face (radio module) and the antenna.
The SiloPatrol®inventory monitor “smart” sensors (Refer
to Bulletin 343A) can be used in conjunction with the
SiloTrack™Inventory Management PC-Based Software
(Refer to Bulletin 343B). Communication between the
Model SMU “smart” sensors and the SiloTrack software is
accomplished via 2-wire RS-485 communication format.
The SiloPatrol Wireless Communication Interface can be
used to replace the RS-485 wiring between the “smart”
sensors and the PC. With reliable and affordable tech-
nology, the SiloPatrol Wireless Communication Interface
can be used to lower the cost of installation and to over-
come obstacles that make hardwiring impractical or
impossible.

MECHANICAL INSTALLATION
Communication Interface (Radio Module) Mounting:
1) Desk Top: The unit is packaged such that it can simply
rest on a desktop next to the control system (i.e.
SiloTrack).
2) Wall mount: A universal mounting plate supplied with
each Wireless Communication Interface can be
attached to the back of the enclosure with the two
screws provided. Secure plate to the wall using the
holes in the mounting plate that best suit the installa-
tion. Do not modify the enclosure in any way as its
weatherproofing and the internal electronics may be
compromised. Instead, make any modifications to
mounting plate.
3) Rail mounting: (See Figure 2 & 3) It is anticipated that
the Wireless Communication Interface will be mounted
to conduits or railings located on the top of the silo.
The universal mounting plate supplied with each unit
can be attached to the back of the enclosure with the
two screws provided. Determine the piping diameter,
source suitable conduit clamps (not provided due to so
many possible sizes) then clamp the mounting plate to
the conduit/railing. Various hole patterns are provided
in the plate to permit optimum clamp sizing. Do not
modify the enclosure in any way as weatherproofing
and internal electronics may be compromised. Instead,
make any modifications to mounting plate.
4) Cable entrance positioning: In outdoor applications,
mount the box with the conduit openings facing down-
wards. If installing with conduit, be sure to provide a
drip loop (i.e. a section of conduit that is more then 6"
lower then the box, with a means to disperse any accu-
mulated water in the conduit so that water does not
pour into the box). Likewise, if installing with cable and
the cord connectors provided, position a drip leg in the
cable (i.e. a portion of cable that is more then 6" lower
then the box so that water will tend to run down and
away from the box entries).
Antenna Mounting: (See Figure 4)
1) Direct attachment to Wireless Communication
Interface: The standard antenna (rubber ducky style)
from Monitor has a right angle fitting that attaches
directly to the side of the Wireless Communication
Interface (radio module) enclosure. Once screwed in
place, the antenna can be rotated as desired.
2) Attached through coaxial cable to Wireless
Communication Interface: Higher performing anten-
nas (Monitor's extended range antenna or similar) must
be connected to the Wireless Communication Interface
(radio module) enclosure with a coaxial cable. Since
the cable restricts the effective range of the radio sig-
nals, it's recommended that the cable be kept as short
as possible. In these cases the antenna should be
mounted to a supporting structure using its own mount-
ing bracket. Then the cable can be connected as a
bridge between the antenna and the side of the
Wireless Communication Interface enclosure.

ELECTRICAL INSTALLATION
Permanently Connected Equipment:
Disconnecting devices shall be included in the system
installation. The disconnects shall be within close prox-
imity of the equipment, accessible to operators, and
marked appropriately as the disconnect for the associated
circuit. Assure the disconnect ratings are appropriately
sized for the circuit protected (See Specifications).
Circuit Separation:
Two cable entry locations are provided to aid in maintain-
ing separation of “hazardous live” (typically mains volt-
ages such as 115VAC and 230VAC) and limited circuits
(typically control voltages less than 30Vrms or 42.4VDC
such as the data communication signals). However, since
the Wireless Communication Interface's single wiring
compartment can not absolutely protect against physical
contact between multiple circuits, it is required that all
wiring used must have an insulation rating of 300v mini-
mum, and a temperature rating of 176˚F (80˚C) minimum.
Protective Earthing:
Each Wireless Communication Interface is provided with
a "protective conductor terminal" which shall be termi-
nated to the local earth ground potential. This terminal
shall be used to eliminate shock hazard in the unlikely
event of internal insulation breakdown. Select wire size
that can carry in excess of the sum of all circuit's maxi-
mum amperage.
EMI Optimizing: (See Figure 5)
Ferrite beads are provided for installation in the wiring to
minimize affects of EMI. Wrap the large ferrite bead with
the incoming power wires (including protective earth con-
ductor) two to four full turns through the bead’s core.
Wrap small ferrite bead with incoming data wires (RS-232
or RS-485) two to four full turns through the bead’s core.
Position each bead immediately inside the cable entrance
of the enclosure.
Power Input:
1) 115 or 230VAC Source: (See Figure 6) Verify the
intended voltage supply is compatible with the voltage
configuration indicated on the electronics and the
external nameplate. Standard mains supply voltage
(115VAC or 230VAC as ordered) can be connected to
the unit's L1 and N terminals.
2) 12VAC Source: (See Figure 7) A dedicated, isolated
12VAC supply voltage can be connected to the +L and
-L terminals. This feature allows for a more convenient
means to power the unit without the concerns of sup-
plying high voltage. This source could be a wall trans-
former or flange mount transformer, with 12VAC output,
5~10VA rating (reference Stancor #STA-4112A (wall,
plug-in) or Stancor #P-8392 (chassis mount)).

Data Communications:
The Wireless Communication Interface can receive data
communications through one of two wiring media: either
RS-485 half-duplex or RS-232. Before wiring, determine
which data communication wiring medium is to be tied to
the Wireless Communication Interface and proceed as fol-
lows (Refer to Setup section for further explanation).
1) RS-232 Connection (if applicable): (See Figure 8) A
single network SiloTrack/PC system can be connected
directly to the Wireless Communication Interface using
the PC’s RS-232 serial port. RS-232 is intended for
use in office environments where interconnection dis-
tances are short (less than 12 feet) and where heavy
electrical circuits (motors, contactors, etc.) are not
present. The interconnection must be done point-to-
point (no multi-dropping or networking) with a 3-
conductor cable (such as Belden 9533 or Alpha 6303).
Determine the type of connector on the PC, source a
suitable mating connector (See Table 1) then intercon-
nect as described in Table 2.

a) The wired circuit connecting the control system
(SiloTrack)and the Wireless Communication
Interface,
b) The wired circuit connecting the second Wireless
Communication Interface and the sensors (SMUs in
the field).
Each wired circuit operates most effectively when the
interconnection has only two ends. “T”s should be
avoided whenever possible. Observe polarity when
making the communication interconnection (D+ and
D-). Attach the cable shield to the "SHD".
2) RS-485 Connection: (See Figure 9) The RS-485 pro-
tocol permits network interconnection of multiple
devices such as the control system (SiloTrack), sen-
sors (SMUs), Auxiliary Output Enclosures (AOEs),
Remote Display Units (RDUs) and Wireless Communi-
cation Interfaces. Devices on this “network” are inter-
connected in a daisy chain, multi-drop configuration
using a 2-conductor shielded cable (such as Belden
9322 or Alpha 6302). Order of connection is not impor-
tant (i.e.the Wireless Communication Interface can be
connected between SMUs if necessary). The Wireless
Communication Interface creates a “wireless link” that
replaces a section of the RS-485 wiring. This break in
the wiring results in two wired circuits:

SETUP
Initial Setup: (5 setup selections required before use)
1) Radio channel: The SiloPatrol®communication sys-
tem only allows 16 sensors per network. In single net-
work (16 or less sensors) applications, a single radio
channel is sufficient. All Wireless Communication Inter-
faces expected to be on the same network of 1-16
SMUs must be set on the same radio channel. The
rotary switch (See Figure 8 or 9) will select the RF radio
channel that you wish to operate on (selections 1-7,
others are invalid). In applications with greater than 16
sensors, multiple networks are needed. When multiple
networks are required and Wireless Communication
Interfaces are used, different radio channels are need-
ed for each network to assure data from one control
system network does not collide with data from a dif-
ferent control system network. (Note: For clarity and
convenience, when using a SiloTrack system, it may
be desirable to match the radio channel with the net-
work number. This should not be confused with the
SMU sensor address.)
2) Master: (See Figure 8 or 9) This selects the medium
that the control system (SiloTrack) will use to commu-
nicate to the Wireless Communication Interface. A
jumper clip is provided for selection. Position jumper
clip on the two pins associated with one of three possi-
ble selections:
RS232: Select this if the signal from the control system
(SiloTrack/PC system) is delivered to the Wireless
Communication Interface via RS-232 medium. This
implies that the Wireless Communication Interface is
on the control system side of the “wireless link”.
RADIO: Select this if the signal from the control system
(SiloTrack) is delivered to the Wireless Communication
Interface via the “wireless link”. This implies that the
Wireless Communication Interface is on the sensor
side of the “wireless link”.
RS485: Select this if the signal from the control system
(SiloTrack/PC system) is delivered to the Wireless
Communication Interface via RS-485 medium. This
implies that the Wireless Communication Interface is
on the control system side of the “wireless link”.
3) Slave: (See Figure 8 or 9) This selects the medium
that the slave sensors (SMUs) will use to communicate
to the Wireless Communication Interface. A jumper clip
is provided for selection. Position jumper clip on the
two pins associated with one of three possible selec-
tions:
RS232: Not used (never an appropriate selection for a
slave).
RADIO: Select this if the signal from the sensors
(SMUs) is delivered to the Wireless Communication
Interface via the “wireless link”. This implies that the
Wireless Communication Interface is on the control
system side of the “wireless link”.
RS485: Select this if the signal from the sensors
(SMUs) is delivered to the Wireless Communication
Interface via RS-485 medium. This implies that the
Wireless Communication Interface is on the sensor
side of the “wireless link”.
4) RS485 load: (See Figure 8 or 9) This switch is used to
terminate the RS-485 link to achieve maximum com-
munication reliability. If no RS-485 communications is
to be used, simply turn “off” this switch. If there is to be
RS485 communications, then you must determine if
the Wireless Communication Interface is physically on
the end of the RS-485 wiring circuit. If so, then the load
switch should be turned “on”. If the Wireless Commu-
nication Interface is not at the end of the wiring circuit
(i.e. two wire pairs branch off in two different directions)
then this switch should be turned “off”. This evaluation
should be conducted for every device on the RS-485
network.
5) SiloTrack Timeout: When using the Wireless Com-
munciation module, the SiloTrack “Timeout” must be
set for 200ms. Time out is defined as the amount of
time between each SMU query by SiloTrack. The
default for SiloTrack is 100ms. To accommodate the
time required for the “radio link”, change setting to
200ms as follows on Windows-based PCs:
a) “Click” Start
b) “Click” Run
c) Open REGEDIT (type in); “Click” OK
d) Select/expand following folders by “clicking” on +
symbol
- HKEY_CURRENT.USER
- Software
- Monitor Technologies
- STCOMDRIVER
- Communications
e) “Click” TIMEOUT (within Communications)
f) Change “Value Data” to “200” (decimal).
g) Close registry editor
h) Reboot computer to engage new TIMEOUT
Indicators: (See Figure 10)
(Four provided for reporting status)
1) Power: The green POWER indicator will light when
power is applied to the unit.
2) Query: The red QUERY light strobes when the control
system (SiloTrack) is querying the SMU sensors. This
is normally a continuously repeating action occurring
about every 1/4 second.
3) Reply: The red REPLYlight will strobe when the Wire-
less Communication Interface sees a response from
the SMU sensors. This will only occur when sensors
with valid addresses are connected.
4) Error: The red ERROR light will flash when:
a) An illegal radio channel was selected (other than
1-7)
b) An illegal master/slave combination has been made.
This could be if the same medium was chosen for
both the slave and master or if radio was chosen for
a medium, but a radio was not installed
c) A check sum error was detected

Fuse Replacement:
The fuse incorporated into the Wireless Communication
Interface SMU PCBs is not intended for operator replace-
ment. A qualified technician can replace the applicable
fuse according to the following specifications. If neces-
sary, consult the factory for additional technical assistance
or for return of the Wireless Communication Interface.
115VAC
F1: 5x20mm, 0.125A Time Lag (Slo-Blo), 250VAC
LittelFuse #218.125
Bussmann #GDC-125mA
230VAC
F1: 5x20mm, 0.063A Time Lag (Slo-Blo), 250VAC
LittelFuse #218.063
Bussmann #GDC-63mA
Preventive Maintenance:
The Wireless Communication Interface is virtually mainte-
nance free. In typical applications, once the apparatus is
properly setup, it will operate without any further attention.
The electronics are housed in a weatherproof enclosure.
In addition the PCBs are conformal coated with a silicone-
based material to further prevent electrical influence by
condensation. The electronics should periodically be
observed for any signs of contamination caused by
improper enclosure protection (i.e. insure cover is fully
engaged, and that wire entries are properly sealed.)
Cleaning Requirements:
In the event that the antenna is fouled by external con-
tamination, reliable communication of the RF wireless sig-
nal may be degraded. In these cases, clean antenna with
a soft damp towel.
MAINTENANCE
Support Functions: (See Figure 10)
1) RUN/TEST switch: This slide switch determines mode
of operation:
RUN: For normal operation of the Wireless Communi-
cation Interface, set switch in this position.
TEST:Use this selection for testing the radio link
between Wireless Communication Interfaces. Testing
can be conducted with or without connection of the
actual control system (SiloTrack) or sensors (SMUs).
At the Wireless Communication Interface on the control
system (SiloTrack) side of the “wireless link”, set the
switch to “TEST”. At the Wireless Communication
Interface on the sensor (SMU) side of the “wireless
link”, leave switch in RUN position. This will force the
control side radio module to emit a test signal to the
radio. When the sensor side radio receives the signal,
it will reply back to the control side with a confirming
test signal. The visual effect of a good link is when both
units indicate a QUERY blink, followed immediately by
a REPLY blink. This will cycle about every 0.5 sec-
onds. If the REPLY does not blink, then wireless link is
bad. The error light will flash briefly if a test signal is
received, but does not have a proper check sum, thus
indicating that the content and integrity of the signal is
suspect. (Note: for a valid check of the radio link, only
one Wireless Communication Interface on the sensor
side of the “wireless link” (with same radio channel
selection) can be active/powered during testing. Apply
power only to the sensor side Wireless Communication
lnterface that you wish to test.)
2) RESET switch: This push button switch will induce the
Wireless Communication Interface to re-initialize the
entire system's operational software.

PROBLEM: SiloTrack™occasionally displays a “COM
error” for a specific vessel
CAUSE/SOLUTION:
1) This error is caused by the inability of SiloTrack to
continuously receive a return response from a
SMU. Brief dropouts of communication can be
expected in wireless radio links, especially during
periods of severe weather. If dropouts are unac-
ceptable, see alternate suggestions below.
2)Confirm that there are no other Wireless Communi-
cation Interfaces on the control side of the “wire-
less link” set to the same radio channel.
3) Verify proper termination of the RS-485 wiring.
4) Consider altering radio installation positions for
best line-of-sight, highest elevation, and no
obstructions (especially metallic).
5) Consider installing a higher performance antenna.
PROBLEM: SiloTrack continuously displays a “COM
error” for a specific vessel
CAUSE/SOLUTION:
1) This error is caused by the inability of SiloTrack to
ever receive a return response from the SMU. This
can be caused by a variety of issues, many not
related to the Wireless Communication Interface.
2) Verify the SMU's sensor address corresponds to
the SiloTrack node (channel) number.
3) Verify that each SMU on the network has a unique
sensor address selection.
4) Verify electrical power is connected to the SMU.
5) Verify polarity of the communication connection.
6) Verify proper termination of the RS-485 wiring.
7) Verify RUN/TEST switch on each Wireless
Communication Interface is set to “RUN”.
8) Verify that SiloTrack TIMEOUT is set for 200ms.
9) Verify that SMU software is revision V1.01 or
greater.
10) Proceed to the following PROBLEM/SOLUTIONS
pertaining to the Wireless Communication Inter-
face. Continue to proceed down the items until
problem is solved. Some may not apply.
PROBLEM: The green power LED does not light
CAUSE/SOLUTION:
1) This error is caused by the lack of power connect-
ed to the Wireless Communication Interface.
2) Verify electrical power is connected, that it is the
proper voltage as indicated on the nameplate, and
that the magnitude is within the specified limits.
3) Verify status of fuse F1. If blown, examine the con-
nections and environment in an attempt to deter-
mine why fuse blew before replacing.
PROBLEM: The error LED flashes
CAUSE/SOLUTION:
1) This error is normally caused by improper setup of
key selections. In some cases the flash may signi-
fy that the wireless data link is being influenced
(See above regarding “occasional” COM error).
2) Verify radio channel selection (Only 1-7 are valid).
TROUBLESHOOTING
3) Verify the master/slave selection settings. These
settings can not be identical.
4) Verify that the radio module is installed. If a radio
is not plugged into the main PCB, a “radio” setting
for master or slave will not be accepted.
PROBLEM: The query LED is not strobing
CAUSE/SOLUTION:
1) This error is caused by the Wireless Communica-
tion Interface not receiving the commands from the
control system (SiloTrack). Identify if the Wire-
less Communication Interface in question is on the
control side (SiloTrack) or sensor (SMU) side of the
“wireless link”. Then:
Control side of “wireless link”:
2) Verify electrical connection and polarity between
SiloTrack and Wireless Communication Interface.
3) Verify that the "master" selection on the Wireless
Communication Interface matches the communica-
tion media (RS-232 or RS-485) used to deliver sig-
nals from the SiloTrack to the Wireless Communi-
cation Interface.
4) Verify that the "slave" selection on the Wireless
Communication Interface is set for “Radio”.
Sensor side of “wireless link”:
5) Verify that the Wireless Communication Interface
on control side of “wireless bridged link” is indicat-
ing “query” by a strobing LED. If not, check steps
2-4 above then continue.
6) Verify that the radio channel selections made on
the two Wireless Communication Interfaces form-
ing the “wireless link” are on the same channel
number.
7) Verify that the “master” selection on the Wireless
Communication Interface is set for “Radio”.
8) Verify performance of the “wireless link”. It is possi-
ble that the radio installation position and/or the
antenna performance are insufficient to successful-
ly achieve a wireless link. See above regarding
“occasional” COM error. The RUN/TEST switch
(See Setup) can be useful in determining if a suc-
cessful “wireless link” can be established.
PROBLEM: The reply LED is not strobing
CAUSE/SOLUTION:
1) This error is caused by the Wireless Communica-
tion Interface not receiving responses from the
SMU sensors. IMPORTANT:Before proceeding
with these steps, make sure the “query” LED is
strobing on both Wireless Communication Inter-
faces performing the “wireless link”. If not, proceed
with steps as described above “query LED is not
strobing”.
2) Verify that the “slave” selection on the Wireless
Communication Interface on the sensor side of the
“wireless link” is set for “RS-485”.
3) Verify electrical connection and polarity between
the Wireless Communication Interface and the
SMU sensors.

General Safety:
CAUTION! It is essential that all instructions in this man-
ual be followed to ensure proper operation of the equip-
ment and safety of operating personnel. The use of this
symbol is used throughout manual to highlight important
safety issues. Please pay particular attention to these
items.
Electrical Shock Caution:
Certain Wireless Communication Interfaces are powered
with HIGH VOLTAGE. No operator serviceable parts are
inside. All servicing is to be performed by qualified per-
sonnel. Each Wireless Communication Interface is pro-
vided with a “protective conductor terminal” which shall be
terminated to earth ground potential (See Electrical
Installation). This product's design complies with
EN61010-1 overvoltage category II and pollution degree
2. When installing certain high performance antennas, it
is critically important that the antenna not come in contact
with overhead power lines. Doing such may put operators
at risk of electrical shock that may be harmful or fatal.
Electromagnetic Compatibility (EMC):
The Wireless Communications Interface contains trans-
mitter module FCC ID: OUR9XTREAM. This enclosed
device complies with Part 15 of the FCC Rules. Operation
is subject to the following two conditions.
1. This device may not cause harmful interference
2. This device must accept any interference received,
including interference that may cause undesired
operation.
