Rev 5 User Manual - 6 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
The time and expense of running wires often makes it difficult to
monitor parameters that have an economic impact on your plant
operation, but the Switch Input Transmitters allow you to quickly and
accurately monitor those devices at a fraction of the cost, which
gives you bigger and faster returns on your instrumentation
investments.
The Transmitters communicate in a secure, digital protocol over a
band of frequencies from 902 MHz to 928 MHz. This data
communication technique has been the backbone of the military’s
secure communications protocols for many years. These devices
require no wires, permits or licenses, and they are easily set up and
installed right out of the box.
You can use this device for long term monitoring in remote
locations, for short-term data gathering on process conditions, or to
quickly test the economic viability of a new installation.
The purpose of this Guide is to help you install and maintain your
Wireless Dual Discrete Input Transmitter. Before setting up and
installing the Transmitter, please setup and configure the Base
Radio.

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
If the “RF OFF” message is being displayed on the Transmitter LCD,
perform the following:
• Set the RF CHAN setting equal to the Base Radio’s RF
Channel.
If “NO RF” is being displayed on the Transmitter LCD, check the
following:
• Is the Transmitter set to the above listed configurations?
• Is the Base Radio on?
• Are the Transmitter and Base Radio set to the matching
configurations? (See Section 5 of the Transmitter and Base
Radio User Guides)
• Are the Base Radio and Transmitters unable to communicate
due to obstructions or distance? (See Section 3.1.1 Transmitter
Positioning).
Warning! If the Transmitters have been running for an extended
period of time with no signal from the Base Radio (the Base
Radio is off or not present), the Transmitters will only search for
the Base Radio every one hour or so. Turning the Transmitters
off and back on will cause them to begin searching
immediately.

3. Installation
This section discusses both the mechanical and electrical areas of
installation.
3.1. Mechanical Installation
In this section, mechanical installation instructions are discussed for
the various setup capabilities of the Switch Input Transmitter.
The Honeywell Wireless Dual Discrete Input Transmitter is a rugged
device, but it provides much better performance if installed with
careful consideration, as noted in this guide. It may be utilized in any
dry contact switch input service so long as care is exercised to
prevent exposing the switching elements to excess stress or
temperature. Installation practices have a lot to do with these
service parameters and the life that you can expect from your
Honeywell Wireless Dual Discrete Input Transmitter.
Give careful consideration to the environment where you will be
installing your instrument. Avoid installations that expose the device
to excess temperature, high vibration, considerable shock, or
exposure to dripping condensate or corrosive materials. Also avoid
installing the device in an unserviceable location.
Most often these problems can be avoided with some thought at the
time of installation. The practices noted below are generally
recommended, but they can only act as a guideline and cannot
cover all possible variations. The final installation must be made at
the discretion and approval of the user. You must be the judge of
the actual installation.
Dimensioned mechanical drawings for aid in mechanical installation
are located in Section 8: Technical Specifications.
3.1.1. Transmitter Positioning
Correct positioning of the Transmitter will ensure the best
performance of the device. When planning the positioning of the
Transmitters there are a few parameters that must be paid attention
to:
• The top of the Transmitter should point in an upward fashion.
The bottom of the Transmitter should NOT point directly at the
Base Radio and the Transmitter LCD should point away from
the Base Radio.
• All Transmitters should maintain an approximate spacing of at
least six feet apart from one another. Should you need to put
Transmitters closer than six feet, please see Section 3.1.1.1
entitled “Technique for Close Positioning of Transmitters”.
• The line of sight range between a Transmitter and Base Radio
is 2000 feet at the 19.2K baud rate setting. Note that this range
is reduced by the amount of RF Noise present, obstructions,
and the material properties of the obstruction.
Rev 5 User Manual - 11 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
• Only place the Transmitter in ambient operating temperatures of
-40°F to 185°F (-40°C to 85°C).
Figure 3-1, shown below, gives examples of incorrect setups
according to the previously mentioned parameters.
Figure 3-1: Examples of Incorrect Transmitter Positioning
Because there are so many setup possibilities we cannot cover
them all. A correct setup would make sure that the above warnings
are heeded, and that the Transmitter and Base Radio are capable of
communication. The RF Placement Test section will help you to
determine if you have selected the correct installation points and
orientations for your application.
Warning! During installation do not apply force to the
instrument housing or antenna. Use a proper wrench for all
installations. Failure to use correct installation procedures can
cause damage to the Transmitter.
3.1.1.1 Technique for Close Positioning of Transmitters
Transmitters may be placed closely together by carefully following
this procedure. If this procedure is not followed, the communication
range of the Transmitters will be significantly reduced and the
Transmitters may eventually lose communication with the Base
Radio entirely. This procedure is easy to implement, but please read
carefully for a full understanding.
The Base Radio synchronizes with the Transmitters in synch groups
of 7,organized by their RF ID numbers. If you want to place two
Transmitters closer than 6 feet, make sure that you have set them in
Rev 5 User Manual - 12 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
different groups. Note that this only applies to Transmitters that are
communicating with the same Base Radio. The groups are defined
in the following table:
Group RF ID Range
1 1-7
2 8-14
3 15-21
4 22-28
5 29-35
6 36-42
7 43-49
8 50-56
9 57-63
10 64-70
11 71-77
12 78-84
13 85-91
14 92-98
15 99-100
For example, if two Transmitters are placed one foot apart and
ou can also ensure that closely spaced Transmitters maintain
ither way, following this process will keep the Base Radio and
the first Transmitter has an RF ID number of 027 that means it is
in the 4th group (22-28). The second Transmitter must have an
RFID number that is in another group (less than 22 or greater
than 28). Setting the RF IDs of two closely spaced Transmitters
so that the RF ID numbers are greater than 7 apart ensures that
the Transmitters are in different Base Radio sync groups. This
allows the closely spaced Transmitters to properly receive their
synchronization signal from the Base Radio and maintain their
proper communication and range.
Y
their synchronization with their Base Radio by simply assigning
each of the two closely spaced Transmitters to talk to a different
Base Radio.
E
Transmitters properly synchronized for long-term
communication.

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
3.2. Testing Communications
Remember, proper placement of the Transmitter will optimize
your RF communication range and capabilities. Perhaps the best
test to perform before mechanically mounting the unit is a quick
hand-held test. There are two types of tests you can conduct: the
RSSI (Received Signal Strength Indicator) Diagnostic and the
Link Test. The RSSI Diagnostic measures the strength of the
signal at the Transmitter. The Link Test measures the throughput
of data sent to and from the Transmitter. The Link Test may be
conducted from the Transmitter, Base Radio, or through WMT.
The RSSI Diagnostic should be conducted first to determine if
the Base Radio is communicating with the Transmitter. Then the
Link Test may be performed to test the validity of the installation.
To perform these tests you should have a good idea of where
the Base Radio will be placed (for more information see Section
3 of the Base Radio User Manual). Place the Base Radio in the
desired area and power on. Make sure that the Base Radio and
Transmitter are on the same RF Channel and Baud Rate (See
Section 5). You may also have to increment the number of
Transmitters with which the Base Radio is communicating (See
the Base Radio User Manual Section 4.3).
Once both the Base Radio and Transmitter are set up to be on
the same network, make sure communication is established by
looking at the Transmitter LCD for the ‘RF OK’ message in the
Read-Only Sequence (see Section 4.2.1).
After communications have been established, go to Section 3.2.1
for the RSSI Diagnostic or Section 3.2.2 for the Link Test.
3.2.1. Transmitter RSSI Diagnostic
The Transmitter should be placed in RSSI Diagnostic mode to
determine the signal strength at the location of the equipment to be
monitored.
The RSSI Diagnostic, located in the Transmitter’s diagnostic menu,
displays the RF signal strength in one of seven ranges. The signal
strength is displayed on the LCD using a combination of ‘>’ and ‘_’
characters. Full signal strength is displayed as “> > > > > > >” while
minimum signal strength is displayed as “> _ _ _ _ _ _”. If the
Transmitter is not communicating with the Base Radio (i.e. NO RF),
all underscore characters will be displayed (“_ _ _ _ _ _ _”).
The RSSI is measured every time the Transmitter receives a
message from the Base Radio. The signal strength of the received
message from the Base Radio is calculated during this time. The
actual signal strength in dBm for each range is shown below:
Rev 5 User Manual - 14 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter

-95 dBm
-95 dBm &
-90 dBm
90 dBm &
-85 dBm
-85 dBm & -
80 dBm -80 dBm
To place the Transmitter in RSSI Diagnostic mode follow the menu
map shown in Figure 3-2. Note that the RSSI menu is under the
DIAGNSE menu and not the CONFIG menu.
Figure 3-2: Menu Map to RSSI Mode
Now that the Transmitter is in the RSSI mode, bring the Transmitter
close to the equipment you wish to monitor. Look at the LCD; notice
the ‘>’ will constantly fluctuate. One should estimate an average
value based on these fluctuations. The ideal signal integrity is seven
arrows.
Once you have verified that you are receiving a signal, you should
check to make sure the Transmitter is communicating properly with
the Base Radio. To do so, exit the RSSI by pressing ENTER, and
then navigate to EXIT? of the diagnostic menu and return to the
Operations Sequence shown in Figure 4-1 in Section 4.2.
If you see a NO RF message, then you do not have satisfactory RF
communication with the Base Radio. If your application allows,
move the Transmitter to a different position and check again for
communications. If your application only allows you to mount at this
particular point, you may want to try a slower baud rate setting for
an increased range.
Note While using a slower baud rate increases communication
distance, it also increases the minimum transmit time. See Section
5.2 for a list of the fastest transmit rates for each baud rate. This
may not be suitable for your application.
One final solution is to reposition the Base Radio. However, this
may affect communications with previously installed Transmitters,
and if so, may require the use of a second Base Radio for your
application. To select a better spot for the Base Radio, see Section
3.1.1 of the Base Radio User Manual.
Rev 5 User Manual - 15 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
3.3. Link Test
The Link Test measures the wireless link performance of a
Transmitter running in its normal operating mode. Messages are
sent from the Transmitter to the Base Radio at a predefined
interval called the Transmit Rate (see Section 6.1). Each
message contains data for the previous time period (since the
last transmit). The Link Test looks at the wireless performance
going in both directions, from the Transmitter to the Base Radio
and vice versa, and comes up with a rating. The result that
appears on the display shows the determined link strength.
In order to perform this test, the Transmitter must be
communicating on the same channel and baud rate as the Base
Radio. See Section 5 to configure communications.
The Link Test may be conducted from the Transmitter, Base
Radio, or through WMT. Running the Link Test from WMT is
ideal for testing communications for an installation with remote or
hard-to-get-to Transmitters. To conduct the Link Test from a
Base Radio, see Section 3.2.2.2. To conduct the Link Test from
WMT, see Section 3.2.2.3.
3.3.1. Conducting a Link Test from the Transmitter
The Link Test is located in the Transmitter’s diagnostic menu
(see Figure 3-3).
Figure 3-3: Transmitter Link Test
Using the NEXT and ENTER buttons, navigate to Link Test, and
press the ENTER button to begin the test. The Transmitter will
begin to test the link in both directions (to and from the Base
Radio). During this time, the word TEST will appear on the LCD
display. When the test is complete, the Transmitter will display
the quality of the link. Be aware that the Transmitter uses the
configured Baud Rate and transmission rate to perform this test.
The length of time it will take to perform this test is dependent
upon how fast the device is normally transmitting.
Rev 5 User Manual - 16 -
08/06

Honeywell Industrial Wireless Wireless Dual Discrete Input Transmitter
When enough messages have been observed, a link strength
will be shown on the display. >>>>> indicates the strongest link,
while > indicates the weakest link. The Link Test will continue to
be evaluated and the rating on the screen may adjust itself.
Keep in mind that the longer the Link Test runs the more data
the Transmitter will have to evaluate.
The Transmitter installation site should strive to place the
Transmitter in a location where it receives the highest number
possible. A stronger link means less data re-transmits and better
battery life.
3.3.2. Conducting a Link Test from the Base Radio
When the Link Test is conducted from a Base Radio, it measures
the link strength between a selected Transmitter and the Base
Radio. The Link Test data must be configured to match the
communication parameters of the Transmitter from which you
want to test. The Link Test is located in the Base Radio's
diagnostic menu (see Figure 3-4).
To conduct a Link Test from the Base Radio, Navigate to Link
Test, and press the Enter button. Next enter the RF ID for the
Transmitter that you want to test. Then select the Normal
Transmit rate that matches that of the Transmitter. If the
Transmitter is transmitting at a different rate than the one you
select in this menu, your results will be invalid.
Once the Normal Transmit Rate is selected, the Link Test will
immediately start. The Base Radio will begin to test the link from
the Transmitter. During this time, the word TEST will appear on
the LCD display. When the test is complete, the Base Radio will
display the quality of the link. Be aware that the length of time it
takes to perform this test is dependent upon how fast the
Transmitter is normally transmitting.

In the top of the window, you can configure the test to run for a
specified amount of time. The longer the test, the more data the
test will have to do an evaluation. Type the length of time that
you want to run the test and click Begin to start. Once the test
starts, WMT will reconfigure the Transmitter’s Transmit Rate to
the fastest possible for the selected Baud Rate. These rates are
listed in Section 5.2. After the test has completed, it will restore
the previously configured Transmit Rate.
During the test, the communications reliability is evaluated while
the Transmitter is running under normal operating conditions. As
the test runs, a link strength will be shown in the lower right hand
corner of the window. >>>>> indicates the strongest link, while >
indicates the weakest link. The Link Test will continue to be
evaluated and the rating on the screen may adjust itself for the
specified amount of time.
