HMI Panel Instruction Manual
1.0 Introduction
1.1 Description
The SmartWireless™ Human Machine Interface (SW HMI) panel is a read only remote display unit
designed to operate with Detcon’s RXT-300 wireless transceivers. It consists of an SW HMI module
which provides an operator interface to an RXT-300 network and displays real time status of all configured
network devices up to a maximum of 32 devices. Devices can be sensors, alarm stations, repeaters and
other remote displays.
The SW HMI panel utilizes a non-intrusive magnetic interface operated by a small programming magnet
and displays the real time status of devices on a backlit LCD. In normal operation, the SW HMI panel
provides real time display of device number, gas concentration, device tag and the status of other field
devices like Detcon’s Smart Battery charge levels, network RF signal quality and various fault diagnostic
conditions affecting either an individual field device or the network in general. The front panel LED
indicators provide the status of a device’s three alarm levels (Alarm 1, Alarm 2 and Alarm 3) and fault.
Command functions such as alarm test and radio silence are included as well as additional features such as
alarm inhibit, alarm reset and alarm silence (acknowledge) functions.
The SW HMI module is available in a choice of two enclosures. The first enclosure type is the Model SWHMI-32-N4X which is housed in a NEMA 4X water proof enclosure and has a built in power supply that
takes in 110/220VAC and outputs 24VDC. External DC power (11.5-30VDC) can also be provided by the
customer to power the remote display if AC power is not available or desired. This unit provides DIN rails
which are used to mount the power supply and terminal blocks. The required RXT-300 wireless
transceiver and custom terminal board (8-Position) will need to be purchased separately for this enclosure
type.

Figure 1 SW HMI Panel N4X Enclosure
The second enclosure type is the Model SW-HMI-32-N7 which is housed in a NEMA 7 explosion proof
aluminum panel enclosure. Due to this enclosure type, the unit’s internal space is limited and cannot
support a built in power supply or DIN rails. It comes preassembled with an RXT-300 wireless transceiver
and derives its power from a Smart Battery Pack enclosed in an aluminum condulet with a custom terminal
board, all installed on a custom mounting plate. The SW HMI’s advanced design takes advantage of a low

1.2 System Operation
The heart of the SW HMI is the non-intrusive magnetic interface with backlit LCD display. The display
receives real time data from RXT-300s using RS-485 Modbus™ RTU protocol. The SW HMI includes a
primary Modbus™ interface (COMM1 Master) used to receive concentration and status directly from the
RXT-300 transceiver (Slave) being monitored. A secondary Modbus™ interface (COMM2 Slave) is also
available which is used for communication with another remote display where the SW HMI is seen as a
slave device. The SW HMI panel only monitors the network and does not perform the actual polling of
sensors and processing of alarms. It only provides the user a visual status of the system including fault
conditions and managing of alarm events such as alarm inhibit/reset/silence. Wiring of an external manual
switch is also available to act as an Acknowledge/Reset button. This switch comes preinstalled for the
N4X enclosure and is optional for the N7 enclosure (See section
3.3 Optional Remote Alarm
Reset/Acknowledge Switch (N7 Enclosure)).
1.3 RXT-300 Wireless Transceiver
The wireless function of the SW HMI panel is made possible by Detcon’s RXT-300 wireless transceiver.
This transceiver transmits signal data such serial Modbus™ and can support up to 32 devices. It operates at
2.4GHz and conforms to non-licensed radio frequency appliance usage around the world. Wireless
network integrity and security is accomplished using direct sequence spread spectrum wireless mesh
technology. Wireless applications can be as simple as a single field device communicating with an SW
HMI panel or any number of field devices forming a network of subscribers. Every device in the network
is capable of functioning as a router and repeater for all other devices in the network. This means that
subscribers can “hop” through neighboring devices to communicate with each other thereby widening
network access points. This unique and innovative technology is designed to create a robust network that
automatically routes around congestion and line-of-sight obstacles while improving throughput as
subscriber device density increases. The RXT-300 also provides a network wide control processing
capability. Refer to its instruction manual for more detailed information.

Figure 3 Terminal Board
The available battery pack for the SW HMI panel N7 assembly is Detcon’s plug-in Smart Battery Pack
which provides an output of 12VDC and allows the assembly to be remotely mounted without the need for
any cables because of its wireless operation (See
Figure 4). If installed, the RXT-300 transceiver will
detect the battery and will continuously query the battery pack for remaining battery life. The battery pack
consists of rechargeable Lithium-Ion batteries and is equipped with integrated safety electronics that
include fuel gauge, voltage, current and temperature monitoring circuits. This “smart” circuitry
continuously monitors the battery’s condition and reports critical status information to the wireless
transceiver via the Modbus™ registers. The battery pack is designed to plug onto an 8-pin Beau connector
on the terminal board and should not be exposed to outside elements without being housed and protected.
Only Detcon products specifically designed to utilize these battery packs should be used. Operating
periods before recharge will vary based on devices attached along with the transceiver and the usage of
those devices, but can be as long as 2-3 months and battery life can be up to 5 years before battery pack
replacement is required. Improper use of the battery pack may be hazardous to personnel or the
environment and will void the warranty.
SmartWireless HMI Panel Instruction Manual Rev. 1.0 Page 3 of 20
HMI Panel Instruction Manual
Figure 4 Smart Battery Pack
NOTE: The SW HMI panel can also be powered by a customer provided external DC power
source on connector J5 of the terminal board with a voltage range of 11.5-30VDC.
1.5 Quad Battery Charger (Optional)
Detcon’s Smart Battery Pack can be charged as needed using Detcon’s optional Quad Battery Charger
which can charge up to four battery packs at one time. The Quad Battery Charger comes with a plug-in
AC/DC adapter that plugs into a standard 120VAC outlet for power. The DC end of the adapter plugs into
the DC power jack of the charger providing 24VDC. The Quad Battery Charger has four charging ports,
each with 8-pin Beau connectors for battery pack connection. The ports and connectors are keyed to
prevent incorrect positioning and connection. Each port has its own “FAULT” LED indicator and
“CHARGE” LED indicator and will display either a red light or green light depending on the status of each
battery being charged. Charging times will vary depending on the charge state of each battery pack, but a
full charge of a depleted battery pack can take up to 24 hours.
Figure 5 Quad Battery Charger
When first powered on and with no battery packs connected to the charger, all the LED indicators on the
Quad Charger should be green. When a battery pack is seated into a charging port, the “CHARGE” LED
will change from green to red indicating the battery pack is not sufficiently charged. Once fully charged,
the LED will change from red to green and the battery pack is ready to be used.
The “Fault” LED should remain green indicating that there are no problems with the battery pack or
charging port. If the “Fault” LED turns red with the battery pack connected, then there is a problem or
issue with the battery pack and it should not be used and be removed immediately. If the “Fault” LED
SmartWireless HMI Panel Instruction Manual Rev. 1.0 Page 4 of 20
HMI Panel Instruction Manual
turns red without a battery pack connected to the charge port, then there is a problem or issue with the port
and that port should no longer be used.
Battery packs can remain connected to the charger even after a full charge indication (Green “Charge”
LED) is shown due to the protection circuitry of the battery pack which prevents any overcharging issues.
1.6 Solar Panel (Optional)
Detcon also offers an optional solar panel to be used in conjunction with the Smart Battery Pack. It
provides 24VDC output and connects to the J5 connector of the terminal board. This option enables
continuous operation of the HMI panel and charging of the battery pack eliminating the need for external
recharging. It is an ideal choice for virtually any area with sufficient daily average sunlight. Since the
solar panel is considered and external power supply, a special conduit installation will be required.
If the optional solar panel is installed, consideration should be given to position the panel where the most
sunlight is available. The solar panel can be mounted remotely to allow for maximum sunlight exposure.
If necessary, a sunshade can be used for the HMI panel assembly to help reduce its operating temperature.
Figure 6 Solar Panel
1.7 RXT Wireless Configuration Tool (Optional)
The RXT Wireless Configuration Tool (WCT) is an optional device designed to configure Detcon’s RXT300 transceivers. The WCT is used to configure and change the wireless channel on a collection of RXT
transceivers and to configure RXT-300 wireless networks which interface with the SW HMI panel
assembly.
The RXT WCT is a lightweight and powerfully equipped device with a 10.1” touch panel widescreen LCD
for display and user input. It interfaces with a USB wireless radio that enables communication with
wireless radios of the same type installed in RXT-300 transceivers allowing for their configuration. It can
be powered by 100-240VAC with the supplied AC adapter or operate off of the internal rechargeable
battery for up to 8 hours on a single charge. Refer to its instruction manual for more detailed information.

4.0 Initial Start-up
The HMI display will power up as soon as power is applied. There is no external power switch to the unit.
NOTE: Before applying power, check to make sure that all the wiring connections and
external devices are installed correctly.
NOTE: Applying power with devices hooked up incorrectly may cause damage to the
equipment.
When power is applied to the unit, the unit will boot up and display the firmware version and proceed to
sync with the network if a previous configuration exists. The firmware information will be shown as:
DETCON INC
SMARTWIRELESS HMI PANEL
VERSION #.##
If a previous configuration does not exist, the user will be prompted to auto configure the network from the
HMI display. After the unit has been configured, the unit will begin normal operation. If the unit has been
configured properly, the unit will display the current status of the devices that it is connected to. Reference
section
5.3.1 for more information on auto-configure.
NOTE: The RXT-300 wireless transceiver interfaced to the HMI display must be properly
configured prior to HMI configuration.
5.0 System Operation and Configuration
The setup of the wireless network is critical for proper operation. All RXT-300 transceivers in the network
must be configured properly to allow the HMI to communicate with them.
5.1 Operator Interface
The operator interface of the HMI unit is accomplished via four internal magnetic switches located above
the unit’s backlit LCD display behind the glass cover. The four switches offer a non-intrusive interface and
allow for complete configuration of the HMI. These switches are labeled: PROG, “u” (Up Arrow), “v”
(Down Arrow) and ENTER. The ENTER switch also doubles as a RESET/ACK switch from the Main
Display only (Not in Menu Mode). With reference to the Menu Flow Chart (See
learn how to navigate the menus and make changes.
The magnetic programming tool (See
defined as a momentary contact (hold) on a switch marker (⊗). For momentary contact, the programming
magnet is briefly held above the switch marker (⊗) and then removed. This action will be referred to as a
“swipe” for the remainder of this manual.
Figure 16) is used to operate the magnetic switches. Switch action is

5.1.1 PROG Switch
From the Main Display, the PROG switch enters into the Main Menu. Once inside the Main Menu, the
PROG switch acts as an “Escape” switch that moves backwards in the menu flow chart.
NOTE: While in Main Menu mode there are no updates to gas readings and hence no alarms
will take place.
5.1.2 “u” Up Arrow Switch
This switch moves the user up the Main Menu flow chart. It is also used to change selected entries
within menu selections in the upward direction.
5.1.3 “v” Down Arrow Switch
This switch moves the user down the Main Menu flow chart. It is also used to change selected entries
within menu selections in the downward direction.
5.1.4 ENTER and RESET/ACK Switch
This switch has multi-purpose uses. The ENTER function is used to accept selections within all menu
screens. The switch is also used to execute the Reset and Acknowledge functions. The Reset function
releases all latched relays if they have cleared the alarm/fault condition. The Acknowledge function
will disengage any silenceable relays that are in a currently active state. This is typically used to
silence alarms once the end-user has assessed the alarm condition. The RESET/ACKNOWLEDGE
function of the switch is only applicable from the Main Display and not while in Main Menu mode.

Houston, Texas
Figure 17 Front Panel User Interface
NOTE: The controller automatically times out of Main Menu mode and returns to the Main
Display after 15 seconds of inactivity.
NOTE: The RESET/ACKNOWLEDGE function is applicable from the Main Display only.
5.2 Main Display Functions
The Main Display is a 1¼” x 6” backlit LCD that has 4 lines by 40 characters. The HMI will group sensors
separately from all other devices displaying sensors first, then all other devices by their configuration order.
In normal operation, the configured sensors will be displayed up to 4 at one time. The LCD then refreshes,
SmartWireless HMI Panel Instruction Manual Rev. 1.0 Page 13 of 20
HMI Panel Instruction Manual
displaying the next 4 sensors and so on. The HMI will then proceed to display all other devices on the
network such as alarm stations, repeaters and other HMIs including itself up to 4 at one time, until the LCD
cycles back to the first 4 sensors and repeats the process. When the HMI is in alarm, the display will stay
on the group with the device in alarm. If two or more devices in different groups are in alarm, then the
display will cycle through all the groups with alarms. The user can manually advance to the next device
group using the arrow switches. This is considered normal operation and each device’s information will be
shown as:
XX> YYY “Device Tag” “Device Status” ZZZ%
XX Represents the corresponding device number as defined by its configuration order.
YYY Represents the gas concentration value for sensors. All other devices will display
“- - - - - -”.
Device Tag Represents the alphanumeric name given to the device during configuration for which only
the first 15 characters are displayed. If the device is in any gas alarm condition, this field
will display “IN ALARM #” for that device. If any device is in fault, this field will display
“IN FAULT” for that device.
Device Status Represents the status of the device. For Smart Battery powered devices, this field will
display the charge level as DD:HH:MM corresponding to days, hours and minutes
remaining of the battery life. If the battery life is greater than 45 days, then the charge
level will be displayed as a percentage. For alarm stations, this value will always be a
percentage of the charge level. If an external DC source is used, “DC POWER” will be
displayed. This field can also display “COM ERR” if any RXT is not communicating with
its appropriate device or “OFFLINE” if the HMI is not communicating with an RXT.
ZZZ Represents the network RF signal quality as a percentage.
Four LED indicators on the front panel show alarm and fault alarm output status. The LED’s represent
ALM 1 (yellow), ALM 2 (yellow), ALM 3 (red) and FAULT (blue) and are labeled respectively.
5.3 Menu Functions
The HMI unit setup is accomplished through the MAIN MENU. The MAIN MENU consists of 7 menu
items:
1) AUTO CONFIGURE SYSTEM
2) RESPONSE TIMEOUT & INTERPOLL DELAY
3) RF SILENCE & INHIBIT TIMERS
4) ALARM TEST MODE
5) SYSTEM DIAGNOSTICS
6) DISPLAY SETTINGS
7) ABOUT SYSTEM
The PROG switch is used to enter the menu mode of the unit by swiping a programming magnet over the
corresponding marker “⊗”. Once in the menus, all Modbus™ polling stops. Sensor values are not read
and alarm outputs are not updated. If the HMI is in alarm when the user enters the menu, it will stay in
alarm until they exit the menu. Upon entering the MAIN MENU, the LCD will display:

Use the down arrow “v” switch to move to the next menu item or use the up arrow “u” switch to move to
the previous menu item by swiping the programming magnet over the corresponding markers. Swiping the
PROG switch again will return the unit to normal operation. When the appropriate Menu Item is found, the
ENTER switch is used to enter that menu item by swiping the ENTER marker.
NOTE: The HMI automatically times out of Main Menu mode and returns to the Main
Display after 15 seconds of inactivity. While in Main Menu mode, there are no updates to gas
readings.
NOTE: The LCD has a backlight that will automatically turn off after a user-defined amount
of inactivity. The LCD backlight will come on automatically as soon as any magnetic switch is
activated. This is a feature designed to save on power.

5.3.1 Auto Configure System
The AUTO CONFIGURE SYSTEM menu is used to automatically configure the HMI panel when a
properly configured wireless network is available. When this feature is activated, the HMI will search for
RXT-300 wireless transceivers in the configured network by polling their Modbus™ addresses. Upon
entering this menu, the LCD will display:
AUTO CONFIGURE CHANNELS
RXT ID:161
SYSTEM CONFIGURED
[RE-CONFIGURE]
The RXT ID number is the Modbus
option of re-configuring the network by performing a one second hold on the “ENTER” marker. The
controller will automatically search for available RXT-300 transceivers and configure the HMI panel.
NOTE: The RXT-300 wireless network must be set up and configured properly using the
Wireless Configuration Tool prior to performing an auto configure.
NOTE: The number of activated devices can be less than (but not greater than) the
controller’s maximum input capacity. The maximum input capacity is 32 devices for Model
SW-HMI-32.
NOTE: An auto configure must be performed each time the network configuration is changed.

5.3.2 Response Timeout & Interpoll Delay
The RESPONSE TIMEOUT & INTERPOLL DELAY menu displays the values for response timeout and
interpoll delay of the HMI panel. Upon entering this menu, the LCD will display:
SET MODBUS TIMEOUTS:
RESPONSE TIMEOUT :500
INTERPOLL DELAY:100
Response timeout is the amount of time in milliseconds the HMI display will wait for an RXT-300 to
respond to a poll request. Ten missed poll responses will result in the device being declared in COMM
ERR. The range of values for the response timeout is 100-1000 milliseconds. The recommended value for
the response timeout is 500.
Inter-poll delay is the minimum amount of time in milliseconds the HMI display waits before sending out
another poll request to the next device. The range of values for the inter-poll delay is 10-255 milliseconds.
The recommended value for the inter-poll delay is 100.
NOTE: The values shown are pre-programmed to 500 and 100 respectively and should not be
altered unless directed to do so by Detcon Factory Personnel.
5.3.3 RF Silence & Inhibit Timers
The RF SILENCE & INHIBIT TIMERS menu allows the user to initiate RF (radio) silence over the whole
network as well as inhibit functionality of alarms in the network. Radio silence terminates communication
between all the RXT-300 transceivers in the network. The inhibit function disables all alarm and fault
outputs on the network. Upon entering this menu, the LCD will display:
SmartWireless HMI Panel Instruction Manual Rev. 1.0 Page 16 of 20
HMI Panel Instruction Manual
RF SILENCE & ALARM INHIBIT
RF SILENCE | INHIBIT:##:##
TURN: ON | OFF | START
# | # |
Select the function by swiping the magnet over the markers of the up or down arrows to move the arrow
prompt “→” to the desired location. A swipe over the “ENTER” marker will activate the selected function.
RF SILENCE is used to prevent the radios from possibly interfering with other RF devices on site (such as
remote detonators). Once set to ON, it will stay on until the user turns it OFF. The values below ON and
OFF represent the number of RXTs that have RF silence turned ON or OFF respectively. If any of the
RXT-300s in the network do not enter RF silence, the HMI panel will display the message:
NOT ALL RXT-300S ENTERED RF SILENCE,
DO YOU WANT TO CONTINUE?
YES NO VIEW
Selecting YES will proceed with implementing RF silence for the selected RXTs. Selecting NO will cancel
the RF silence function. Selecting VIEW will display all the RXT-300s in the network by their MAC
address and their corresponding RF silence status. NORMAL indicates RXTs that are not in RF silence
and RF SIL indicates RXTs that are in RF silence. In RF silence, the sensors are not monitored and no
alarms can be activated.
The INHIBIT TIMERS mode is used to momentarily disable alarms in the system when calibrating sensors
to prevent the alarms from firing. It has a timer range from 0-60 minutes. Once the timer value has been
entered in minutes and seconds, select START and all relay outputs on the network will be disabled until
the timer reaches 0 or is manually stopped by the user.
5.3.4 Alarm Test Mode
The ALARM TEST MODE menu allows the user to simulate alarm conditions and verify relay contacts.
Upon entering this menu, the LCD will display:
ALARM TEST MODE
OFF
A swipe over the ENTER marker will toggle the alarm test mode ON or OFF. When turned ON, the alarm
test mode simulates alarm conditions by incrementing all active device readings from 0 - 100% of the range
in 5% increments. When full scale is reached, the readings will decrement back to 0 and the unit will exit
the test mode. The test mode can also be terminated at any time during the test cycle by turning OFF the
alarm test mode. As the readings cross their respective alarm set points, the relays will fire according to
their configuration.
5.3.5 System Diagnostics
The SYSTEM DIAGNOSTICS menu performs function tests for the LCD display, the panel LED’s and the
external reset switch, if one has been installed. Upon entering this menu, the HMI panel will automatically
initiate a function test that displays every pixel of the 4 line, 40 character LCD display. The unit then
performs a function test of the LED drivers by activating all four LED’s. After the LED test, the unit will
initiate a test for the external reset switch which lets the user know when the reset switch is pressed. The
user will be prompted to “PRESS ENTER KEY TO CONTINUE” meaning a swipe of the ENTER marker.
SmartWireless HMI Panel Instruction Manual Rev. 1.0 Page 17 of 20
HMI Panel Instruction Manual
This will end the system diagnostics test and the display will revert back to the SYSTEM DIAGNOSTICS
menu.
5.3.6 Display Settings
The DISPLAY SETTINGS menu allows the user to customize the brightness, contrast and backlight
duration of the display. Upon entering this menu, the LCD will display:
DISPLAY SETTINGS
BRIGHTNESS: ### BACKLIGHT OFF: ##:##
CONTRAST: ###
These values can be changed by swiping the magnet over the markers of the up or down arrows to move
the arrow prompt “→” to the desired function. A swipe over the ENTER marker will select the function
indicated by the arrow prompt “→” and the value can be changed by swiping over the markers of the up or
down arrows. Another swipe over the ENTER marker will save the selected value. Values for brightness
can range between 0 and 100 in increments of 10. Values for contrast can range between 30 and 100 in
increments of 10. Available values for the backlight timeout function are OFF, 10 seconds, 30 seconds and
1-5 minutes. The backlight timeout is the amount of time the user has before the LCD backlight will turn
off while in the Main Display due to inactivity.
5.3.7 About System
The ABOUT SYSTEM menu displays system information such as the HMI firmware version, the HMI
hardware version, the microcontroller firmware version and the RXT-300 firmware version and device
image. Upon entering this menu, the LCD will display:
